This kind of active subwoofer is oni good for a little bit of bass since its oni 6.5" but if u are talking about going low its quite impossible for such a small subwoofer,on top of that the material use is some kinda metal for the enclosure. Sometime u can even hear voice coming out from the sub too. Frankly speaking I don't like it. Cost wise its just too expensive for such a small subwoofer,for the same amount of money you pay,you can get better subwoofer with lesser money spend.

If you are into pure sq subwoofer,then i will suggest you to get the following subwoofer:

-Seas Lotus SW300 or Seas Lotus SW250
-Phase Evolution Aliante 12 Si Ltd
-Peerless Xls
-Alpine Type X or Type R
etc

Just my 2 cents

aliante ka? sold already now subless boss
