more speakers for rcvr? is this a good idea?
I have put 1 set of 12" cerwin vegas on front, 1 set cv 12" on surround, and have the cv matching center on center. It's a rxv650 I have and I can put another set on rear surr and another set on prescence. I wanted to but 2 sets of matching bookshelf (4 of them) and put one on rear surr, and one on prescence. This means the reciever will be driving 9 speakers at once...isn't that too much for a reciever...like I know if I put all four 12" on front (a+b) then it'd be driving a 4 ohm load and if I drove them hard it'd be too much for the amp so how the hell could it drive 9 speakers safely. If I buy those 4 bkslf speaker + another set of 12" 3-ways for spkr b output, I could put them all on and drive the unit with 11 speakers...Isn't that crazy that it would allow me to do that...isn't that way too much for the amp...even 7 speakers properly set seems like it would push it too much,in 7 chnl stereo espcly. Anyway's what's the deal with these prescence out's what the heck does prescence do and why put prescence if it just means more stress on the unit...If I turn the bass down will it help the unit to function when using more than 5.1 because I think the bass requirement stresses the unit. What would happen if I tried to watch top gun with bass and treble high and used fr sur rrsur ctr prsnce (no spkr b), in other words using those 9 channels at levels like 25db and louder with levels turned up for high iompact movies or techno rap music...Would I blow up the amp? Would I blow spkrs, would it distort. Why let me hook up 11 or 9 speakers and then say I could only use half or less the volume...Why isn't their any warning about that...what about using 11 12" or rather11 15" woofers and then turning it to +15...Why doesn't the instr mnl warn not to over load the receiver like that...why is pluto the furthest star?...why isn't pluto a star? what is a semibeigplutonubularsuperconductingsupercolliderde sktopmodularwindowdashboard3of4starbuldozingdinomo rphorobotplantfoodroboticspacerobotcybergenicrobot icdashboardornament4000sp?

There's a perfect answer/solution to every problem/question...yeah right
Read your owners manuals!
First of all, that receiver uses the same amplifier for the PRESENCE and SURROUND BACK speakers. You then set the receiver to apply priority to one or the other, therefore you would only be running 7 speakers at any one time. I tried that with my RX-V1400 and prefered to not use the PRESENCE speakers. Now on to the A+B speakers. There are, in fact, warnings in your owners manual about impedence. I'm pretty sure that those big CVs you're running are 4 Ohms and I don't recommend running two pairs on your front channel. For now I'd say buy one pair of bookshelf speakers and try them as your PRESENCE speakers for a while and then run them on the SURROUND BACK channels. If you feel that both connections are worth it you can buy another set. Keep in mind that the PRESENCE speakers are intended to be used with the DSP modes.
