Depends on the desired SPL. 65 watts is actually a good amount IF it could put that out will all channels driven. I suspect it can't. But note that you can play fairly loud with just one watt of power - the main need for lots of power is on peaks.
Seems a bit underpowered to me, assuming that it can't do 65x5 all channels driven ( leaving me to wonder how much real power it has.)
