40W doesn't sound (no pun intended) like a lot. Have you tested it, objectively or subjectively, to see how it compares to amps on today's AVR's?
No objective testing, but a couple of years ago I did use one Yamaha M-35
surround amp running in 2x 40W
mode to "acceptance test" a pair of Polk R50
floorstanding speakers I was considering for use as either rear surrounds
or front wides
, by temporarily swapping the R50
s for the usual L|R front main speaker pair in one system. As my systems all use active L|R front main pairs, I added the M-35
to drive the R50
s . . . plus I had to tweak the system's crossover point and bass volume settings to accommodate the more limited bass range the R50
s can deliver. I used DVDs of "Wanted"
and "Master and Commander"
for the test.
The Polk R50
s could not match the smooth power delivery and clarity present in the either the Yamaha AST-S1
active speaker pair I normally use or the Klipsch XF-48
active speaker pair I had recently tested on the same system . . . but I never got any sense that the M-35
amp's power handling was a limiting factor at any volume I might consider for home listening.
As we move toward home theater systems with potentially 4|6|8 or more
height speakers, I'm not sure that we need to provide each one with the same power delivery capabilities as the front L|C|R speakers...?! For example:
This 22.x(?) speaker config in use for the NHK-JEITA SHV TV exhibit at CEATEC Japan 2012 last October (apparently a DSP processing variation from the nominal Hamasaki 22.x layout required to compensate for use of a direct view display . . . and the missing ceiling!
) looks like it contains 10 height speakers
. . . 8 "standard" plus 2 more "non-standard" added just to support dialog lift
