If you've heard LAB subwoofers...you've pretty much heard these. They're very similar, just setup as a push pull / slightly wider / have heat sinks for the speakers. These pictures are them fresh after completion (paid a professional woodworker to fabricate them). They could use a fresh coat of paint (have the bed liner I'll give you).
Looking for $600 each, which is a STEAL.
Pros:
VERY loud for the wattage you throw at them
Sounds absolutely fantastic (VERY low distortion because of the horn design AND the push-pull config)
Free plans available online (the more you add, the lower they go and louder they go).
Cons:
Nobody knows them (resell market slim...just imagine how much these cost to build)
Large (If you're looking for powered QSC cabinets...this is the wrong speaker)
That's about it. They're amazing and If i did sound more, I'd be keeping them. Just getting out of the game.
