receiver compatibility

[Enoch105]

I'm new to all this, but I recently read Audioholics home theater system suggestions for the 3,500 budget system.
I have a Yamaha RX 465 bl, and I'd like to buy Audioholics' suggested speaker system [TS2132T-HT from the speaker company]. Will my receiver have enough power to handle this system?

Thank you!!!

Yes, enough power.

you have 105 watts per channel and it should work fine with the Speaker Company speaker system.

The pre-outs on the 465 are only for the subwoofer(normal) and surround speakers which means you cannot add an additional external Amp for the front and center speakers. However, this is of no concern with the HT speaker system you are looking at.

Good Luck!

Thank you!! Again, I apologize for the beginner questions:
What would cause the need for an additional external Amp for the front and center speakers? Is that something dictated by specific speakers or the room/user preference? Also, would that feature be important enough to upgrade the receiver to a higher model? [665 or 765]

Thanks!

amplifier power gives you two parameters to think about. (1) the power to drive your speakers to a reasonable volume level consistent with the size of the room - without going into distortion and "clipping" - both symptoms of an amplifier driven too hard. (2) any power reserves above what you actually "need" for (1) above is often called "headroom". This allows an amplifier to supply clean power when the music source has large swings in music dynamics. Classical music is an excellent example of music with extremely wide dynamic ranges in the recording. Modern pop and rock music is usually compressed into the higher dynamic range of the recording and does not display the huge swings in power demands. When the music source suddenly needs a large draw of power to project the suddenly "much louder" music, the amplifier has the headroom reserve to do it.

You did not mention the size of the room you will use the TSC speakers in, but as long as it is not a huge volume "great room", your 465 should work OK. The Yamaha Vxx5 series is actually not as well powered as the previous Vxx3 series....more features but less raw power. Let us know the size of your room and anything else that might require a little more powerful receiver so we can comment of the V565/V665/V765

It's a basement theater:
7' ceilings; 10' wide; 15' long

I am trying to put together this system for my brother in law who has difficulty accepting that it might cost him more than $1,000 to get "decent" sound.
Right now with the v465 and tsc system I'm at $900, but I can probably convince him to spend a little more if it will get him a significant bump in performance. Thanks!

The size room you mentioned is fairly small and the 465 will work fine. If your friend is concerned about cost, I would stick with the 465; you should not need an external amp.

There are three main reasons an external amp is needed:

(1) Room Size. larger room - speakers tend to be at higher volume that can tax the receiver output. As mentioned by a previous poster you don't want to run at full volume, to provide some head room for large frequency swings

(2) Speaker Impedance. While the impedance of a speaker varies with frequency most speakers have a nominal impedence rating usually 8ohms. Some speakers are 6 ohms and some very expensive speakers are 4 ohms or even 2 ohms. The nominal ohm rating of a speaker affects directly the power required. Power equals voltage times current and current is voltage divided by resistance so P= V^2/R. Simplyfying 4 ohms requires twice the power that 8 ohms does. Many 4 ohm speakers require an external amp.

(3) Speaker efficiency or sensitivity. This is how well the speaker converts power to sound loudness and is measured in dBs. A low effiecieny speaker ( 80 dB or less) requires a lot of power. Most speakers are medium effciency in the randge of 88-90 dB and require average amount of power. High efficiency speakers are those approaching 100 dB and require very little power to create loud sound.

Good luck and have a pleasant day!
