Speaker Advice

[waynezo]

My setup

Home Theater

Mitsubishi 82" DLP
Kenwood VR-4080 Reciever (.003 THD)
BIC PL-66 Acoustech Speakers
2 Audiosource SW15 200 watt Subwoofers
Sony BDPS-570 Blu-Ray Player
HTPC Media Center 7
Terx Amplified Antenna

I am thinking of adding Pl-76 Towers since my reciever has A and B outputs. The PL-66's are in a wall unit about 6' high and they sound great.
I listen mostly to Jazz Vocals and movies, hard classic rock once in a while.
I wonder if adding the towers will make that much difference?
Any advice will be greatly appreciated.

You can't use A & B speakers at the same time, as A & B use the same amps, and you will blow your receiver up. You never run two set of speakers at once it sounds terrible anyway.

Nice Studio! Are you a sound engineer by trade or an advanced hobbyist?

My Reciever has the ability to play a+b at the same time in stereo only. I guess B is meant for another room.
I could upgrade to the towers and use the PL-66's to replace the generic surrounds I have now. Seems like a waste of a good speaker since so little sound comes from the surrounds.

You have the hang of it.

Often the surrounds are only ambiance. However, quite a few movies now put big demands on the surrounds and rears. There are a number of SACDs that put as much demand on the rears as the fronts.

If the 3DAA has its way, all speakers will have to be equally capable. They are developing a new open source codec, with the 5.1 in the core for backward compatibility. They are developing a new mixing system, with coordinates locating any object anywhere in the room. There is a lot of industry backing, and I think big changes will be afoot in a couple of years, on the audio end of HT anyway.

I personally have all speakers highly capable and it pays off.

Thanks for your remarks on the studio. I have been into audio as a hobby for over 50 years. They did for some reason admit me to AES.

that is because they didn't want anyone seeing you dig through the garbage cans out front .

have done it several times with my Yamaha rxv 659 on 5 channel programming without a problem. If it was that much of a problem, why would they allow you to do it? They would obviously provide for A or B only vs A+B.

They shouldn't allow you to do it. They just want your receiver to have a short life so you have to buy a new one. Unless your speakers are 8 ohm throughout the range, and that's just about none, the amp will see an impedance of four ohms, with A + B selected. That is if the speakers are truly 8 ohms, and that's just about none.

If you speakers are four ohms, most, then when you have A + B your receiver's amps will see two ohms. That will blow it.

I've always believed in using identical speakers all around for MC. I had two complete systems like that. An all JBL L212 system i built up from a stereo system, and years later an all PT800 system. Both systems also having multiple subs. That provides the best sound for DVD-A, SACD.
