What speakers play the loudest cleanly ?

I own the Legacy Focus. I own the Pass labs X 350.5 and I had a Krell KSA 250.
Both Amps could be driven with ear splitting sound if I wanted to and I did not hear any distortion.
The legacy has 3-12" woofers they can take anything you thro wat them.

I will nomiate Kef. They are very clean and clear all the time. I play mine very softly, just above a whisper and you can still make out every detail. At the same time, I've run mine in the 90 dbs and they are spot on. Not a bit of distortion. This is one of their best traits. I would have to agree with a number of the posters that in this same family would be Revel and Tannoy in my experience. One of my favorite things to show people about Kefs is how the speaker form is entirely unaffected by how loud these speakers get. You can place a nickel standing on edge, on the top of the cabinet and play as loud as you'd like and the nickel won't fall over.

Was just thinking of this old thread as I sold my Klipsch RF-83's recently. Anyone else want to chime in?

OHM Walsh. I've owned various models since ~ 1981 and run them both indoors and out. Nothing phases them! Not even my current 500w/ch Class D amp. They just deliver whatever you throw at them.

Once circa 1985 or so, I ran my old Walsh 2s on a farmhouse porch off my old 80w/ch Tandberg receiver for a grad school party going on in a field 50-100 yards away and let it crank like never before. I was shocked. Was that my system or a live group performing on that farmhouse porch? The best sound I had heard ever out of a stereo system ( up to that time).

Also, for small monitors, my Dynaudios go loud extremely well. I believe Dynaudios in general probably do.

Dynaudio...
