What is the best HEAVY METAL speaker?

I am lucky enough to have loudspeakers that Van Halen RUSH Dio Metalica Tesla Judas Priest etc all played through live. I repurposed these horns into modern loudspeakers so when I listen to metal it's just as it should be heard. Through horns that the artists actually used in concert.

Cerwin Vega speakers and heavy metal may be the perfect match. 

I was cranking out Albert King w/ Stevie Ray Vaughan "IN SESSION" today at party volumes on my Klipsch Forte powered by a 40 watt tube amp and getting down with it.

Do the ATC 150s I sold Mettallica count?

I've got a pair of ATC 110s and it's hard to imagine anything better for loud, amplified music.  They can play very loudly without distorting.  I doubt anything can compete with their combination of high volume, low distortion, and excellent in-room behavior. 

I also think they make a tradeoff that other companies should make.  They don't use the port to lower the -3 db bass frequency.  They let the bass roll off slowly starting at a higher frequency.  It means they don't excite room nodes as badly as a typical ported, -3db at 30 hz speaker.  It doesn't make for good marketing but practically speaking, it's better if you want top quality bass and don't want to mess with equalization.  I think it actually increases dynamics, the punch is great, and if you want more bass get a sub to fill in anything you want.
