I should be receiving my new 11 channel LSiM speakers from Polk next week. (Very excited!) I currently run an 11 channel home theater LSi system. My main question is whether I'm living dangerously feeding the same amount of power to the LSiM speakers. I'm currently running 3 Emotiva power amps (XPR-5, XPA-5, and XPA-3) for my LSi home theater speakers. The front and front wides are Lsi-25's, taking an effective 600 watts per channel (at 4 ohms) from the XPR-5. The balance of my channels are running off the two XPA amp outputs (300 watts at 4 ohms).
Key question: will the LSiM 707 fronts and 705 front wides I'm getting be able to handle the 400 watts per channel (at 8 ohms) from the XPR-5?
Secondarily, I also have a Sherbourn 7-350 intended to run the four LSi-25's, together with a current pair of A9's in the bedroom, after they are switched to that location. But I have flexibility to try and optimize output, mainly emphasizing the home theater set up which is where I will do most of my listening.
If the answer is "yes, as long as you don't go crazy with the volume, those Emotiva amps would work in the LSiM HT", then my next question is can I push even more power using the XPR-5 for the towers and the 7-350 for the other seven channels in the HT?
I would highly value any advice based on real-world experience.
Here are the full HT speaker assignments:
Fronts: LSiM 707's
Front Wides: LSiM 705's
Front Highs: LSiM 703's
Center: LSiM 706c
Surrounds: LSiM 702f/x's
Rears: LSiM 703's
Subs: Dual SVS PB-12-Plus
