So nice o got it twice

This thing slams. I got one to add to a pair of mma124's and loved it so much I had to get another. I am running somewhere between 500-700 watts rms to it in a 25hz tuned enclosure. This sub SLAMS for a budget build.

Decent sub for the money, slams hard. Probably a little bit overrated power wise. Have it hooked to a power acoustic rzr Coil gets warm after a couple minutes at full tilt.

Good for the price.

Decent sub for the money, slams hard. Probably a little bit overrated power wise. Have it hooked to a skar 800.1 @ 2ohms. Coil gets warm after a couple minutes at full tilt.

Great budget sub

I have 2 of these on a JP8, roughly 1000 wats real power. They sound good and get loud, but the lowest notes do tr reproduce quite as well as I had hoped. I upgraded to NVX and they reach down much better on thw lowest lows, despite not yet being broken in. I will upgrade the amp to a JP13 after the break-in period. For the $250 I paid for the pair, they can't be beaten. At the current asking price of $350 for a pair, they are just OK.
