Speaker recomendation

There's a very nice demo pair of Acoustic Zen Crescendo IIs here now for $12k.  They are an easy load so should work fine with your current amp, but they will certainly reward you for upgrades down the road.  Best of luck. 

The Acoustic Zen are okay speakers and were never worth their original price point we heard them on numerous shows. Also they are not 96db efficient so they are not going to play as loudly as easily to fill up a large room as the Legacy's.

My listening space is 16.5' X 34' w/cathedral ceiling. I built a pair of custom Tannoy HPD 315 (ca 1975 12" dual concentric drivers), that are rated at 94 db sensitivity. I get very enjoyable sound with either a 500 Wpc Class D amp, or a 9 Wpc SET 300B.

You may want to opt for the 15" version for your situation, should you consider them. They treat all genres of music equally well (with the possible exception of Hip-Hop or electronic synth, which I've never heard through them). I used vintage drivers, as I could not afford the current Prestige line of Tannoy, which are beautifully enclosed in fine cabinetry.

Tannoys will reflect improvements made in the gear that drives them, are explosively dynamic when called for (they still scare me at times, even after eight years of listening to them), and are very robust.

Just another avenue for you to consider, and in my mind, a very suitable one for your needs.

Best of luck, regards,

Revel F228be + Anthem STR Integrated.  You’ll have plenty of power, ARC to help tame errant reflections in the room, a beautiful set of speakers that can play louder than you’ll ever need without breaking a sweat and can handle anything from light acoustic jazz to full orchestral recordings to heavy metal with aplomb.  

Plus, with the STR Integrated you get real bass management so if you want to add a subwoofer or two later on it’s plug-and-play easy.  

I just heard Legacy Audio(Focus SE) speakers for the first time. I think they sound really good and represent outstanding value. I would love to hear the Aeris as possible replacements for my speakers.
