the box Pyrit 212 Sub

Plugged this bad boy into the Behringer iNuke NU4-6000 into one channel bridged (which outputs 3000W@4Ohm) so plenty of power behind it. I couldn't turn up the volume on the amp more than half which I expected, and at that point items were falling off shelves and the cat went into hiding.

Best used with an EQ so you can focus only on the frequencies that give a deep rich bass and the Pyrit doesn't disappoint, have used at multiple parties (150 - 200) people and everyone comments on the sound quality -

I'm using this in conjunction with the Samson Aura 12's (400W RMS), between both they give nice reproduction.

Its a heavy beast with two carry handles, you can 'drag' it yourself (watch your ankles though) but best to have a hand moving it around, I'll be ordering a second one when funds allow.
