Looking for new speakers for large audio room

Get the used pair of Egglestonworks Vigintis for sale here on Audiogon (no, they are not mine, but I do own a pair).  They are $19,900.

With moderate power (300 wpc), I have never, ever felt the need for a subwoofer-- pitch perfect bass-- that you can feel when it's part of the music, and very pleasant dynamics and balance overall.

Fremer really likes them too, and Mikey, well, he can be fussy.

might I suggest klipsch jubilee active

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.
