Difference Between Ava 15" and 18"?

Silver Member Username: Sx3Illinois USA Post Number: 134 Registered: Mar-05 | Would there be much difference between an 18" Ava in a sealed box and a 15" Ava in a ported box? Each running off a Hifonics BX1000D or BX1500D. |

I am runnning my 15 at 2.5 cu/ft sealed off of about 900-1000 watts and it SLAMS and sound very nice also |

Silver Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 612 Registered: Sep-04 | no... thats what it was going to be... now im building appx 10cuft gross ABC box.... ABC boxes require a lot of sapce... thats why it is so big... they actually limit the excursion of the sub though allowing you to put more power to the sub as long as you dont exceed the limits of the VCs |
