I am not the biggest Eminence fan, but I admit this speaker has really impressed me. It is loud, clean, light and has a very "punchy" bottom range. It has a peak in the upper mids, but I flattened that out by running an inductor in series. Now it sounds almost HiFi-like and works fine as a PA. In fact, this speaker has much cleaner and better reproduction than my Yamaha Club Series 12" PA speakers!
I upgraded my EBS ProLine 210 with the Deltalite II 2510s, and my 210 then became as loud as the normal 410. The 210 easily took all the output from my MarkBass LMII without sounding bad or bottoming out. And I have used them for over five years now, and they still sound and look like new. Top product!
