Large speaker recommendation

I would look for (what I have, imagine that):

3 way, 15" woofers. Solid directional bass.

no ports, or if so, front mounted only, option to close them.

efficient enough to allow you to try tubes some day.

Your space seems unproblematic, but you never know for sure.

How do you adjust them to your listening space?

Many of the big speakers in the old days had level controls. Even the smaller AR-2ax’s I just restored have level controls.

My 4 L-Pads are wonderfully difficult. However, I get the best response possible. After doing it ’by ear’ for 48 years, I finally bought an inexpensive sound pressure level meter and have a test cd with selectable individual frequencies. So easy, so good!

Even without level controls, the meter on a tripod at listening position, and test tones help you refine locations, and toe-in, perhaps alternate toe-in, one for you in the center, another for two listeners, each off-center.

IMO: Now that they are so inexpensive, speaker makers should add L-Pads again, and include a meter and test cd in the box!!!

Why don't you go with cremonese from Sonus Faber? Once you settle on Sonus faber everything else will sound disappointing to you 

Considering the amplifiers you own you are not restricted om your speaker choice. I'm going to throw out an alternative that I think would be worth considering.

I own a pair of Thiel CS6 speakers driven by a Krell KSA 300S. I've been to two audio shows (AXPONA & Tampa) and I can comfortably say that my system stands up to modern speakers costing in the upper 5 figures. I was pleasantly shocked at how well my system compared with nearly everything I heard. The CS6s get everything right but they particularly excel in imaging. If pinpoint, almost spooky imaging is your thing these speakers fit the bill.

Last I checked there were a few pairs of CS6s for sale for between $2k and $4.5k. For a pretty low cost you could try a pair and see if they perform as well for you as they do for me.

Repair of Thiels is still available through Coherent Source. Rob Gillum worked for Thiel and can repair most Thiel drivers. You can read a review in Stereophile and there is a long thread called "Thiel Owners" on Audiogon.

I rarely recommend these speakers because very few people have the amplifier to drive them. They have low sensitivity and a brutal impedance curve but your MLs were designed for exactly this kind of load.

I would like to thank everyone for your valuable inputs. Many of the speakers recommended here are totally new to me. So I had to google them. The looks are obviously a very personal thing. I narrowed down to a few and started auditioning them in my own room based on the availability from my local dealer. The first ones I auditioned were Wilson Sasha 2 and Revel Salon 2. Just as some of you pointed out, they sound very differently from the Elipsas. Not sure I like the sound but may just need time to adjust. Next up is Rockport Atria II. They also have Focal, Estelon, YG, MBL, most of which are above my budget. Would definitely try a pair of Raidhol and Vandersteen when they become available. Will see....thanks again.
