The speakers really sound amazing. By far the best speaks I have ever owned. I would put them against the new Reference 1 any day. I prefer the soft dome tweeter on the older KEF’s. You are really good man!

You know Chef, I don't think I gave you enough credit 

These speakers are absolutely wonderful, hard deep bass, crisp, sharp mid's, treble that is infinite, clean & clear. So I just wanted you to know is that now I've had some time to sit back & enjoy my L-150A's Thanks Again Loudspeaker Chef.

Installed them, and they sound outstanding! I have had them a long time (since 1976), and I think this is the best they have ever sounded!

Thanks very much!

I just wanted to give credit where credit is due. Man Chef you sure do make an excellent x-over. Just got my L-112's back from the shop, completed & sounding sweeter than fine wine. Boy do your x-over's make a huge difference.
