Home Audio Speakers

does polk audio speakers for home theatre is a right fit?
Will onkyo tx sr 805 with polk audio RM 6880 speaker system will make a decent home theatre set up?

Polk are decent speakers and will work well for home theater.

But there are HUNDREDS of other brands out there. Some are a lot more accurate & detailed. But you are pushing $2,000 per speaker to get the increased accuracy.

Also - newbies often post:

"For $500 - which of these 3 speakers are the best?"

and a fight ensues with no truthful answer.

Dont be this Newb.

Speakers have 'flavor'. What I like and what other posters here like wont be the same. And there is no good way to measure/rate speakers from best to worst.

The safest advice I can give you is that you should take a CD (Not a DVD movie) and try and listen to several speakers, including the Polks you are considering. It should be a favorite CD. If the Polks make your familar music sound good - put them on your short list to buy.

Then leave the store.

Come back in a few days with a different CD and re-listen. Whatever speaker sounds good on 2 different trips - buy them.

Your ears quickly become fatigued. If you listen to crappy AM music on the way to the store - every speaker sounds good. If you listen to a high-end speaker system, then go to the more budget models - they will all sound like crap.

Be aware of this and make 2 visits to avoid over buying.

stores.ebay.com shop.ebay.com This amazing pair of vintage horn speakers was found in Phoenix, AZ by vintage audio collectors and eBay sellers ...

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.

Can somone please explain to me which of these statistics should be lower, and which should be higher for optimal sound quality.

Thanks!

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.

Price: $599.95

Features 0.5-inch silk and polymer-composite dome tweeter in each satellite speakers
Six piece surround sound package that includes 2 front and 2 surround speakers, 1 center-channel speaker, and 1 subwoofer
Satellite and center-channel speakers utilize 3.25-inch polymer-composite cone drivers for distortion-free midrange
Satellite and center-channel speakers can accommodate 6.1 or 7.1 channel systems
Subwoofer utilizes an eight-inch long-throw dynamic-balance poly-composite driver for longer driver excursion and better linearity

Do they somehow run on a different method, or is a speaker a speaker regardless of where it is being powered from, whether it be a cars amplifier, or a home amplifier?

Yes, it's quite a bit different. Home speakers are made for closed boxes meaning they are enclosed in a box to get more dynamic sound whereas car speakers are made for more of a free air environment. Also another thing is most home speakers run at an 8ohm resistance while most car speakers are 4 or 2ohm. I'm guessing you are asking this because you want to put home speakers in your car or car speakers in your house, yes it can be done but it won't sound quite the way it was intended.

I have two infinity floor standing speakers, each has an 8" low range driver. Im curious why the sound, both spl and range, are much like that of my JL 12" w6v2 subwoofer in my car. Ok maybe not spl, ive never experienced my sub putting out more than 1/2 power. They are so different, the 12" being massive, both by competent companies. Why is it that from appearance they are so different, yet in sound they are so much the same?

Essentially, the larger the speaker, the more efficient it is.

A small 4" speaker when fed with a 100Hz tone will sound very much quieter then a 8" or 12", because the bigger speakers cones can vibrate more air particles then the smaller 4" or so speaker can.

Also, bear in mind that the car sub is designed as a sub, most likely with a tuned and ported box, to make the sub box's resonate frequency somewhere in the middle of the bass frequencies - say 60-100Hz or so - making them most efficient(read: loud) at those low bass frequencies, plus car subs are normally driven harder then house subs, to produce more thumping bass from a relatively small sub box.

Your house speakers are more wide-band, in that they tend to try to emphasize all frequencies - bass, vocals and treble.

They get good sound, but require a larger volume box to produce the goods across the whole audio spectrum.

House speakers too are built with the woofer as the top priority, 2nd the midrange speaker, and last is the tweeter.

This is why most modern bookshelf-type stereo speakers(without a separate sub), lack bass, yet some big floor-standing speakers sound great due to the bigger box volume.

Sub boxes only need to work with bass frequencies, and pretty much flatten out any vocals and high-frequencies are almost undetectable to the ear in these boxes.

It's all to do with acoustic tuning of the speaker in question, to the box it is in.

I'm looking to upgrade my stereo system with a new pair of 3-way speakers, everything I see seems to use a dual woofer configuration. My current speakers use a single 12 inch woofer with two horns, one for the midrange, and one for the high end. my main concern is not going "Backwards" in relationship to what I already have, "Rock" solid bass.

they are using 2 smaller speakers vs one larger because they are faster , quicker (sound - cleaner) more acurate .
