Ground Zero GZIB 3.250SPL boxed subwoofer (3x250 mm).

Ground Zero GZIB 3.250SPL boxed subwoofer 10" (3x250 mm).

GZIB 3.250SPL includes new GZIW 10XSPL subwoofers.
Do you want a subwoofer that plays lowest lows with authority and hits hard with higher notes? It is now possible to buy completely built. 
And in an enclosure that definitely does not take your whole trunk. 
This enclosure with three drivers has an excellent sound quality, bass response goes very low and higher notes are also played with precision and kick. 
And still you can fit this box to almost any family wagon and hide it under the curtain. And you still have space left in the cargo area. 
We recommend to get an amplifier that can deliver about 2000 watts to 1 ohm load to get all the joy out of this fabulous box.
