op you are barking up the wrong tree
your amplifier has more then enough power
changing to greater efficiency loudspeakers wont fix it nor will eq
low levet listening involves the flecher munson curve which dictates the ear is less adept at hearing low bass at lower levels you might think adding a sub would fix tha it wont as a good woofer just adds pressure to the leading and trailing notes of the totems the man sound is just coming from the totems
and an eq is too likely to muck up your tonal balance without offering enough finessee to fix the issue
having heard the totem forests for years you need a warmer fuller sounding loudspeaker with greater mid-bass response
please lk at a pair of Legacy signatures or a pair of Harbeths to completely give you what you are craving.
