How does impedance relate to sound quality in home audio speakers?

I am in need of new speakers for my new home theater system, however as tech savy as I am, speakers are not my forte. The current speakers I run are 8 Ohm impedance, 150W, 91DB Sound pressure, with 36Hz-22Khz range. These are Onkyo Fusion AVs. I need a good pair of slim line speakers, and I have found a few that I like however I am not sure how they compare with my current set.

You want your speakers to handle your system's output power, so you'll need at least 150W speakers.

The 91 dB sound pressure is an indication of the efficiency of the speakers. Higher is more efficient, lower is less efficient. Remember that dB is logarithmic, so a 3 dB change is a factor of 2 (88 dB uses twice the power to sound as loud as your 91 dB speakers).

A key spec of the frequency range was left out, and that is the variation from one frequency to another -- i.e. +/- 3 dB. Ideally, you'd like +/- 0 dB so all frequencies would sound the same with the same power input, but that's not going to happen, so most spec how close they come to the ideal. A speaker with +/- 0.5 dB across the frequency range will sound far more accurate that one that is +/- 3 dB (remember that 3 dB is a factor of 2).

The wider and flatter (+/- 0dB) the frequency range, the better.

Impedance by itself generally doesn't relate to sound quality; you just need to match your amplifier's preference for best results.

But remember that the specs are the manufacturer's specs, not independently certified specs. You'd do well to consult audio review magazines for their test results of the speakers you're thinking of instead of believing the manufacturer's specs. They aren't perfect, either, but they will probably be more objective than the OEM.

There are a number of ways to hide a flat panel television when it is not being used by incorporating the feature into the overall home theater room design. Some use a static image to display a piece of art or favorite family picture. Others use elaborate mounting unites and screens to cover the television when it is not in use. A professionally design theater system can incorporate any idea you have to make the room beautiful both when in use as well as when not.

Below are some display options available for home owners as they consider how they want their flat panel television to be concealed when not in use.

Screensaver Displays

Since many LCD TVs are simple displays like those used by computer users, they can be set to display art and photos when they are not in use. Using a screensaver however does require the television to be on so it is not recommended for long stretches of time. It is best for use during parties.

Customized Art Covers

Custom art overlay options are becoming more common. A specialized piece of art on a canvas can be made to be placed over the screen when homeowners are not using the TV. This is an inexpensive solution that does not require any new wiring or customized mounting.

Many homeowners choose to hang their flat panel televisions above a fireplace. For a traditional flare, a wooden frame can be installed around it, thus turning your television into a mantel piece. Professional installers can also design an automated system that slides a screen cover over the flat panel.

Moving Displays

Pop-up and flip-down displays are the ultimate convenience for home theater owners. At the touch of a button, the screen can be brought up from an inconspicuous piece of furniture or down from the ceiling. This technique is especially useful with flat panel televisions that need to be installed at the foot of the bed; the television can be placed on a motorized lifting mechanism that can move the television up while watching TV before bed and down before you turn off the lights.

Other Considerations

Most home theaters are not comprised of the TV alone. Mounted televisions prove more difficult to integrate into an entertainment system because all the necessary connections need to be run through walls. Wireless technology for these applications is improving but is not yet fool-proof.

Custom home theater installers can offer advice on how to arrange DVD players and receivers to match the subtle look of a hidden flat panel television.

Choosing the right option to hide a LCD TV into a room's design can be difficult. The size and shape of walls or the way they are built can limit the installation options. Place the television in the appropriate spot for viewing, and then start considering installation options.

A car sound or audio system is considered by many people as one of the essential items. A high quality system generally includes an FM/AM tuner, an amplifier, tuner and speakers. In all of these, an amplifier is usually recommended, however it is an optional feature.

Always remember this fact that car audios are not comparable with the system used in homes because a car is small with so many noises and traffic environment all around. So, in such a moving environment it is not important that your system works well. However, before purchasing any system it is very important to search about it. You can simply search through internet to make a best purchase. Check various magazines and reviews about such product to make a wise purchase.

Always try to make deals with well known companies and brands in this regard. Try to make it sure that the company return or exchange components in case these do not suit to your car and requirement. Always try to give priority to the personal tastes. This generally means that many people like country and rock music. For those people stronger range systems are required. On the other hand there are many people who are more interested in classical and light music. For that purpose system with soft and mid ranges are also suitable.

It is better to compare various systems so that you can judge which one really suits to you and your car. Two types of components used in audio system involve in dash and under dash parts. Under dash parts are easier to install. However, remember under dash parts are not so safe and thief can easily slip out these parts. Amplifiers are usually used to set various ranges and tones. These amplifiers are big enough and bulky so these must be installed carefully under a seat or in trunk.

After buying amplifiers remember that you should buy such speakers that can better go with these amplifiers. They must be compatible with each other. So you can purchase both of these components in a single package to avoid any further inconvenience.

I recently purchased a Sharp aquos 42d62u LCD TV and get bad motion blurr on HD sports channels. Any solution

Watching one of the bowl games last night on FOX and it was particularly bad - eventually just tough to watch. Any suggestions??

I own the 64u that has a 4ms response time and have never had any motion blur or ghosting. With your 62u at 6ms you shouldn't be getting any either. I would agree with the others and say it is probably the signal you are receiving. Try another source and see if you have the same issues.

Is this a proper Earth Connection?

Hi all!
I have a home theater system, and was having sort of unwanted humming sound from the speakers (especially from the subwoofer). I've thought that it was caused by the electrical surges of AC . As a matter of fact, I have purchased a surge protector (Belkin Pure AV) in order to filter them. The problem is that the surge protector needs an earth connection to work properly. I opened up the AC socket on the wall, and found out that there wasn't a ground connection there. I thought that the boiler I use must be grounded because it's a necessity for it to work properly. As a solution, I grabbed a wire and hooked it up to the radiator which is connected to the boiler. Then I checked out the surge protector indicator showing that the protection system works properly. So, it works fine, and I got rid of the humming sound mostly. All I'm trying to find out is if the earth connection I made is a correct way, or is it safe?
Thanks.

The ground wire is for excess fault voltage. It carries away mostly static, (your problem exactly). The ground you used for a single outlet should be fine. A surge protector shoots off voltage ( the suppressed voltage rating should be on the surge protector like 330v) to ground. The basic protection of the surge is very high spikes like lightning or a power company fault. But the wire you installed is good for noise on electrical systems. Make sure you put the grounding wire on the green screw that grounds the strap of the outlet. Do Not put the wire you installed on with the white wire on the silver screw. This will cause just the opposite effect and may cause you to be shocked while using the equipment or damage the circuitry.

HOME THEATER-PRO 1 (with before/after pics)

Having the correct equipment when training your dog is essential. It needs to be fit for the purpose to get the best out of your training session. So what is the best equipment for your dog for training?

Whatever equipment you use with your dog, do check it regularly. Check:

• for wear and tear.

• that it still fits correctly. This is especially important with growing puppies.

• for signs of chewing, which could weaken it.

Essential equipment for all dogs:

• A normal collar with either a buckle or clip. It should not have any tightening action, such as a choke or half-check chain.

• A lead. A lead of 4-6 foot is ideal. If it is shorter than this, you may find that your dog will pull more, as he cannot get away from the tight feeling. If it is longer, it can be difficult to control your dog. Most people prefer nylon, leather or canvas leads. Chain can be used, but this can be very uncomfortable.

• Some form of poop scoop is also essential each time you take your dog out.

Alternative equipment:

Head collars work on a similar principle to a horse's head collar, in that they control the head. They are extremely useful with dogs that pull, jump up at passers-by and are more difficult to control. It will not teach your dog how to behave, but it will make it easier to control him while you are teaching. Many dogs are not impressed at first and may scratch and shake their heads. Take your time and introduce it gradually, following the manufacturer's guidelines.

Harnesses are favoured by many people when walking their dogs. It means that if the dog does pull, it will not hurt his neck. However, many dogs can pull more strongly with a harness, and dogs who are required to pull, for example, sled dogs and tracking dogs, would wear a harness for this purpose.

For dogs who pull, there are relatively new types of harness available. They are designed to help while teaching a dog not to pull. They work by putting pressure in a different place when the dog pulls, and therefore he cannot lean into it as he does with a collar. An extending or retractable lead consists of a box which you hold, with a line that extends as your dog pulls. There is a brake to stop. These are useful when you are in a situation where your dog can have more freedom, but cannot safely be off his lead. Please be careful - if they are used near traffic, dogs can still be involved in accidents.

A long line, or old washing line, can be useful when your dog can have some freedom but is not safe off the lead, or when teaching a dog to come when called. Some people find it difficult to use as the excess lead can get tangled. Take care with big or strong dogs - consider wearing gloves to avoid rope burn on your hands. It may be beneficial to use under guidance from an experienced trainer.

Poop-scoop, plastic bag etc. Never leave home without these. Even if you don't need them for your dog, you may be able to donate one to another owner!

audio delay in combo dvd stereo receiver to tv.?

Got a newer dlp tv, hooked up my older onkyo combo dvd stereo receiver to it through video line 1 using yellow, red and white rca. Playing a dvd now there is a slight delay from the speakers in tv and the combo stereo speakers. Very annoying if trying to use both tv and stereo audio. The stereo seems to have the delay. My seven year old three lens rear projection samsung did not have this problem as with this samsung. Why does it do this and is there anything I can do about it...

Goldfish is correct and here's why. Because today's TVS have so many different ways of receiving a signal, the audio must be processed 'decoded' before it can be sent or reproduced.The term is latency. When viewing broadcast received by the set itself, the processor can sync the audio and video because the process is all internal to the set. When an external device such as a separate audio amplifier, the audio and video now take separate paths and are sent through separate processors. The processors do not have the intelligence to re-sync the AV.
As for correction, Some service provided receivers " Cable , Satellite and such " offer audio delay in the user menus. If this is not the case you will simply need to experiment with wiring options. The only other option I can think of would be to purchase a audio processor that provides variable delay.

When you are setting up your home theater you need to decide on what is the best way for you to watch. Many people would not have anything other than a projector as it adds to the cinema theme as well as giving you a very good image as big as you want. But many others do not want to deal with projectors and screens and would rather have the convenience of a TV style screen that you just turn on and play the DVD in as you would in any other room but on a bigger screen.

If you are using a projector then it is a good idea to make sure that your room has good thick curtains so that you can block the light from the room. As the image is produced through a projected light then it is best to use a projector in a fairly dark room. With some of the latest projectors they have a light sensor so that if the light is too bright for the image then it brightens the light to make it stronger. You also have to set up a projector for the movie and put up the screen. But it does give you a really good sense of being at the cinema as well as a really good, large picture that is very high quality.

There are some really good plasma screens around now and the cost is dropping. But you still get the sense that you are watching TV. Although if you put it on the wall then it is a lot more like a real screen. Plasmas have an advantage over projectors if you have a small room, as they did not need any space to project an image. Although plasma TV does not have the same movie theater aspect to it as a projector does it is very easy to use and does give you a very good image.

If you want ease of use and a great quality picture and are happy either to have a smaller screen, or you are able to pay for a very big one, then plasma might be best for you. But a projector can give you a really good quality image that is as big as you want and there are some very good projectors that are very cheap. But you also have to set up the screen as well as the projector whenever you want to see a movie. But whatever you choose it is always worth trying it out in the store so that you can see which is the best for you.

Would a HDMI to VGA cable used on a up-converting dvd player still deliver the upconverted quality?

The VGA input is on a 1080 compatible projector.

Only if the device that converts HDMI to VGA is HDCP compliant.

This screen may be a little small for 120 people, 40 x 40 is a little less than 3 1/2 feet by 3 1/2 feet or 40 inches is about 4 to 6 inches wider than the front door of your house.

If you are putting together a home theater system and have already purchased a projector, you are now ready to buy a screen. While a variety of screens are out on the market to choose from, they can be classified into three basic categories.

Fixed Screen

The first choice is to install a fixed screen in your home entertainment room. The advantage of this type of screen is that because it is fixed on the wall, it can cover the wires and cables. To install it, stretch the screen on the wall and use fasteners to keep it in place. If you have speakers, you can put those on the side or behind the screen.

Tripod Screen

One of the benefits of a tripod screen is its portability. You can take it down after use, fold it up, and put it wherever you would like. However, the screen is going to be a lot smaller than a typical projector screen, but will also be less expensive as well. Tripod screens are ideal more for temporary situations such as meetings or presentations, but not necessarily for home entertainment.

Retractable Screen

A retractable screen is the other option you can choose to go with your home theater projector. You can choose to hang it on your wall or from your ceiling. When you aren't using a retractable screen, you can either manually or electronically retract it. This is a more expensive option, but is ideal if you don't want the screen to be seen while not in use or don't have a lot of space in the room.

Consumers today seem to be drawn to the new age of home theater systems that are space-saving such as soundbars and tiny home-theater-in-a-box systems (HTIBs). If you care about sound, and want the convenience of an all-in-one package then the Yamaha YHT-791BL would be the one to choose.

Standard HTIBs typically come with speakers that are very light, but the YHT-791BL isn't a regular HTIB. The two front speakers weigh over eight pounds and stand 13 inches tall. The surround and surround-back speakers are one and the same, weighing over two pounds apiece, and with the more manageable height and width. All of the speakers are two-way and come with a plastic textured finish which assists with keeping fingerprints at bay.

The size of the speakers decidedly helps the YHT-791BL sound great, but keep in mind that they are bigger than many of the other speakers in the HTIB systems. Yamaha YHT-791BL delivers virtually all of the performance of the higher priced home theater system making it a smart choice for audiophiles on a budget.

The YHT-791BL features Yamaha's Parametric Room Acoustic Optimizer (YPAO) automatic speaker calibration system that sets the speakers and subwoofer volume levels, determines the speaker/subwoofer crossover point, assesses the distances from the speakers to the listener, affirms that all of the speaker cables are correctly hooked up, and uses leveling to balance the frequency-response characteristic of all seven speakers.

The strongest part of the YHT-791BL's connectivity is its four HDMI inputs, which should be enough for most home theaters.

If you need multiroom capability, you'll have to set-up a separate based system as the YHT-791BL isn't a multiroom system.

Overall the YHT-791BL is a home theater system with first-class sound quality which has a clean and clear sound due to the two-way speakers. The Yamaha YHT-791BL home theater arrangement is an excellent all-in-one system for the home theater enthusiast on a budget. Primary components include AV receiver, Speaker system, DVD type: DVD player.

You will find additional information, specifications and discount pricing at the Yamaha YHT-791BL homepage.

i purchased a set of Acoustic Audio GX350 speakers but i don't what kind of amp to get.?

They can handle up to 1000 watts. I also want to know the best placement for these in my trunk to maximize sound quality and loudness.
i also am purchasing a set of tweeters, midrange, and 6X9s will i have to purchase two amps or can i buy an amp that can power all of these

if its a hatch fire the subs up towards the glass.
If in a trunk fire to the rear.

Amp really depends on your budget.
for about 1000rms @1ohm on a budget id look on ebay.
If you have some cash to spend id go to a local shop.

Yes, depending on your options you can use Toslink (digital optical -- the little pentagonal connector with the red light), digital coaxial (brown RCA cable) or 5 red/white RCA-pairs to connect BD to HT (home theater).
I'm guessing you mean you have an HTIB (home theater in a box), so Toslink is your best bet. It is a pure digital transmission with zero electromagnetic interference (because it's literally pulses of light, not an electric signal carried over an inducible copper wire).

We all spend a large amount of time and money making sure that the interior of our homes is right. This is because not only do we want to live somewhere that looks nice but is also very practical and comfortable. As a result of this more and more people are opting to put their Samsung TV's for example on wall mounts rather than conventional floor stands. But how do you know where is the right position in a room for your Samsung wall mount to be placed?

In this article we offer some tips that you may find useful that will determine where in a room is the best position to place the wall mount for your Samsung TV.

Tip 1 - When looking for the position where you are intending to place your wall mounted TV then it is a good idea to make a template from card or paper the size of the TV. Then you can temporarily place this in the position that you are considering installing the wall mount to see if it the best position. Once you have put the template on the wall now sit on chairs in various parts of the room to ensure that you can clearly view the TV screen at all times.

Tip 2 - Along with making sure you choose the right location for your Samsung wall mount make sure that you put it at the right height. In the majority of rooms pictures we hang will be set at a height relevant to our eye sight as well walk around. But when it comes to mounting a TV on a wall it will need to be slightly higher. This not only improves the position that you are viewing the TV from but also prevents your neck hurting as you strain to look at the screen.
