The high efficiency Class D amplifier modules are based on a proven topology that has been continuously refined over the past 4 years. The amplifier has vast reserves of power for highly accurate, deep bass for your home theater or music system.

216 pounds of subwoofer!
Last time the coupon said "max -$300", but it did the 50% off during checkout no problem.
Sigh.
You used to be able to get this sub as an Open Box for $960 and free shipping.
I don't think you could buy the drivers, plywood and a 2000w amp for that, even if you were building it yourself.

Crucial info was left off this post which is the Dimensions:
L27.6" x W20.0" x H42.3"!
Imo at this price, you're better off going with two smaller subs, with very likely a lot more cash in your pocket to boot!

Yes that was an error, some even reported getting their order cancelled.

Who reported that they got their order cancelled?
What smaller subs can do 116db @ 16hz ?
Or 100 db @ 12hz ?
Like they always say, there is no replacement for displacement.
That should not be a surprise.
No one mentioned measurements.
Are you claiming everyone gets those measurements and it "sounds" exactly the same regardless of where you place the sub, where you're seated and how it calibrated/integrated?
