Got a pair? Not enough! Grow another pair! You’re gonna need ‘em! Most people should just stop reading this right now. If you’re slightly demented and want enough bass to crush your skull read on…

The XXX-15 has proven to be the most powerful woofer we’ve ever made. Until now! The big brother is here are ready to cause some serious damage. Tipping the scales at 91 pounds and shipping “freight only” in a wooden crate, SPL competitors can relax if they are part of Team Sounstream. Others beware! The hardest part

about using this beats is mounting it as it takes two people! Don’t even both with cheesy screws, you need nuts and bolts if you want it to stay put.

The XXX-18 is optimized for large vented enclosures. Suggested volumes are included for 4ft3, 6ft3 and 8ft3, but it can go in larger enclosures if desired. Specs are as follows:

Fs 22.9 Hz
Vas 5.504 ft^3
Qms 5.866
Qes .191
Qts .185
QVC Quad 1.2-Ohm Coils with 10 gauge leads – no crappy terminals
BL 19.47
Xmax 30mm
Xmech 45mm – That’s 3.5” of peak-to-peak excursion for you tweaks!
2.83v 99.81dB
Wrms 10,000 watts – Not peak, RMS!

Look, it’s simple… If you want the biggest, baddest stuff on the market, cram a couple of XXX-18 subs and power them with a pair of XXX-15000D amps. Just don’t call us when your brain is splattered all over the windshield!
