I have a dual AA Avalanche 18" IB sub that I installed about 3 years ago. I got the drivers new. They have been driven by a Samson S700 amp (350w/driver). The sub has been awesome, but I recently moved and the new HT is in an open loft and the volume of the room has quintupled. Even though I don't need to fill the entire space with sound, I really want to make the jump from two to four 18" drivers. Three years with the same sub is too long... uprgradeitits has hit again! The combo of the S700 and the two Avalanches is really nice. The amp is quiet so it doesn't need to be in another room.
Now, my story with these drivers and amp. For full disclosure, I have never clipped the amp, but I did soft bottom the subs twice (I think). This was 2 years ago when I was testing it out. While watching War of the Worlds during the seen when the first alien thing came out of the pavement in Brooklyn, I had it turned up louder than I ever had and I had a lot of boost dialed in at 20Hz with a very wide band. I don't even know if it was a true bottom, but I watched the subs from the side and they looked to be moving at least 2.5" peak to peak. There was no clank, but a subtle creak indicating they were stressed. Since then, I've listened with the same volume but no extra boost below 20 Hz... never a problem since. Remember this was 2 yeas ago. So, what that tells me is the S700 is a perfect mate when you don't add output that the drivers weren't designed to reproduce. Don't take that as meaning this cannot produce the low stuff... I've had a house curved dialed in that slowly ramps up from level matched to the mains at 80Hz to about 10dB hot at 30Hz. It stays 10dB hot to 20Hz and then slowly drops back to level with the mains at 10Hz. And, none of this included boost... all I did was cut output from the original naked response. With this curve, it sounded phenomenal. When I dialed in more, I just wanted to see what it could do.
Anyways, this IB combo of two Avalanche 18" drivers and the S700 has been phenomenal, but I've moved and the new room is much larger. If I could sell this as a combo I would be thrilled. $250 per driver and $200 for the amp. Buyer pays shipping and insurance. Local purchase would be ideal (Sacramento, CA).
edit: typo... switched 10Hz to 10dB.
