At $2500 (the price of the AT-1s) you have a TON of great options. Listen to as many as you can ... check out speakers from Dynaudio, Revel, Paradigm, Energy, Ascend Acoustics, NHT, JBL, KEF, Tannoy, B&W ... the list goes on and on.

For flat response on and off axis, and ultra low distortion I'd go Revel Performas on the used market. Actually, that's exactly what I did do ... so I'm biased. I went with M22s but they might be a tad small for your room so the F32 would probably be a better fit for you.

The AT-1s may be fine - even great - speakers but 29hz from a $2500 floorstander is not a huge breakthrough. At the $2500 price point, there are just too many options from far more credentialed speaker manufacturers to put it high on my list.
