is the black hole foam kind of like raam's ensolite?
model on the alpine and the Bostons?
The Alpine looks like a 3552, and if that's what it is, I've got one that needs fixed. Good amps though. Does (rated) 35x4 at 4 ohm, like 55 or 65x4 at 2 ohm, and 85x2 4 ohm bridged. It's supposedly pretty underrated, doing closer to 100 x2 at 4 ohm.
Free bump for a great deal on an Alpine. The last time I saw one, it was a mint one at a pawn shop in Newark, and it sold for 129.95

Alpine is 3552 .... Bostons are the tweeters from Pro 60s ...
Here's the info on the Focal Black Hole :
I have quite a few pieces of Focal's Black Hole Foam that I have treated with Fabric Sealer. It will not mold or mildew , nor will it soak up any water. I can cut it to any size, and treat the edges. I used this is my doors behind my drivers , but it can also be used in sub-enclosures , trunks , ect ...
Here's some info on the material from Focal's original web-site :
Black Hole 5 is a complex multi-layer material system that combines three key functions; damping, isolation, and absorption. The overall thickness of Black Hole 5 is 1-3/8", but. Optimized for use in speaker enclosures, as well as any other acoustical dampening installations. All layers are laminated together using a special thermal process, without the use of adhesives or solvents.
Layer 1 - High loss vibration damping material (same as the Black Hole Pad), deadens resonance from the cabinet. It is very strongly bonded to the wall with PSA film for optimum performance.
Layer 2 - Polyester urethane flexible open cell foam ¼ in. thick. Thanks to its special vibration-isolation characteristics, it de-couples the vibrating structure (the cabinet wall) from the rest of the damping system, thus optimizing its performance.
Layer 3 - Barrier septum 1/8 in. thick. Made of limp flexible vinyl copolymer loaded with non-lead inorganic fillers, it acts literally as a dead wall, thus isolating the vibrations in the walls of your cabinet and the vibrations created inside the enclosure from each other.
Layer 4 - Polyester urethane foam 1 in. thick, structurally optimized for acoustical dampening, (specific permeability, density, stiffness, pore size and shape). It is highly effective at "soaking-up" maximum sound energy with minimum thickness.
Layer 5 - Thin diamond pattern embossing, densified with polyurethane film surface. This unique surface layer improves dramatically the performance of the whole acoustical system, especially the lower mid-bass frequencies, (very sensitive range where simple acoustical foam becomes mostly ineffective).

My buddy wants that amp. Give me your paypal addy and you got 35 bux //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
