Amazing sound- if you can carry it!

Comments about Alto Black 15" Active Subwoofer 2400W:

I have owned lots of subs in all sizes. This might be the best sounding of the bunch. You get a slightly more compact footprint than an 18, and certainly a lower height. But the sound is better than any 18 I've owned, including both the EV and QSC 18. How does it do it? 2 things- tons of power and a massively thick and heavy cabinet. It really proved to me that you can try all the gimmicks in the world with amps, materials, and such. But nothing beats good old fashioned girth! So bottom line is- if you're a mobile guy (or band), find a comfortable cart system to move it. But even picking it up off the cart and into the truck/car/van is a challenge. A better use is in semi-permanent installs. 1 for a small venue, or 2 for a church or larger space would be KILLER.
