Looking for new speakers for large audio room

More bass and a larger room, keep the Avant-garde speakers and upgraded the subs

Look into D+S tech labs Hathor speakers with built in 1000Watt subs for just under 30K you pick the wood finish, call and talk to Bill Daniels he will probably even come out to help set them up if you ask.

B&W 800 D4 series.   I have the 802's and they're magnificent.  

The majority of these speakers if any at all  listed won’t accomplish what your looking do to based on the size of your room, the only real way to pressurize your room with bass and keeping your Pass amps is to upgrade you subs to larger ones and add room correction to dial it in.

I just bought a pair of KEF Reference 5’s.
so far they have been great!

All the best.
