Having a bit of a re-config of my system and need advice on power requirements for speakers to maximise performance. What's got me thinking is a fellow AVF member suggested my LCR are under driven and would benefit from more power to improve dynamic range etc, even at lower volume? He also suggested XTZ's power rating is quite conservative.
See below more info on my present set up for initial advice. Note, I do need all channels driven by external power amps as I am about to introduce 2 x MiniDSP ddrc88BM's to try out Dirac.
So my question is, given that I may well be going to a 9.1.4 config (wides will be XTZ M6's), so will need an extra 2 channels of amplification what wattage rated power amps should I be looking at and should bi-amping the LCR be a consideration? Or am I over thinking it and what's in place is good enough?
Typical listening volume max -12dB.
All speakers crossed over with subs at 80Hz, so subs handle all the heavy lifting in the bass/sub bass region.
Distance from the LCR to the MLP is approx. 10ft.
Set up. (7.2.4)
200w per channel; all channels driven; into 8 Ohms.
300w per channel; all channels driven; into 4 Ohms.
110w per channel; all channels driven; into 8 Ohms.
170w per channel; all channels driven; into 4 Ohms.
Thanks in advance.
