Biamping my RTi12s and CSi5, too much power? [Archive]

So Ive got my RTi12s biamped with almost 450w going to it using two Parasound Amplifiers (One is a 5channel HCA5250, other is a 3channel HCA2003). Then I got the CSi5 doing the same thing, same amps so its also getting 450w. The surrounds are only getting 250w from the 5channel Parasound amp, which is more than enough for the FXi5s.

Do you think Im going to blow that CSi5? I know they recommend upto 200, but never really understood why they put biamp posts on it if it can only handle 200, Both my amps push more than 200 a channel. Ive thought about getting a larger or more powerful center, but I dont think Polk makes one to handle 400-500 range. Plus Im not looking for some other brand as all my speakers are polk (with the exception of my 2nd sub, sunfire true mkiv 10s).

Now I have run the rig full tilt before I biamped by front/centers with the Parasound 5250 which puts out 250x5, and so far the CSi5 been good, no distortion, sounded clean all the way to full power. Just wondering what yall think.

Overkill is good. Your sending your speakers good clean power. Just know your limits with the volume knob.

Well thats good to hear. Yea I definitely know the limits and dont plan on running it at deafening levels, but I love sending clean power (instead of AV Receivers sending it).

So you think swapping out the CSi5 for say the LSiC? I see the LSiC doesnt really accept anymore power than the CSi5 does from their ratings. But at the same time I was worried about throwing the LSiC in there and how it may not match well with the RTi12s.

Stick with the csi5 it's timbre matched with your rti 12's.

Dixit, remember that the majority of the time you will not be sending anything close to 200w to the speakers. But as leroy said with the center ch having much more of the sound track than other channels do not get carried away with the volume level.
