I notice many of those speakers have a horizontal array of piezo tweeters across the top. I didn't see the one you've asked about, but I wouldn't expect good performance from anything having a horizontal array of tweeters. Beyond that, I guess you might want to have a listen and see if they'll meet your needs.

The D-49 is a compression driver,claiming to have the following specs; 115dB, 2000 watts max, 120 oz magnet, 1" vc film cloth.That don't look right to me, magnet weight voice coil and power i don't see it adding up. That's why I wanted a responce from someone who has heard them.

Well, I don't want to be a Negative Nellie but I would not believe the power figure at all, not even close. I would also be suspicious of the SPL figure. I suspect the max power level is more like somewhere between 20 and 200 watts, and the SPL is probably around 105dB/W/M when put on a 90x40 horn. Those are specs of good compression drivers, so even if this thing is top notch, the numbers should fall in line.
