About Black Hole 5
One of the main contributing factors in the clean output of a sub is a solid non-resonant enclosure. Solid granite walls, sand filled walls, heavy bracing and heavy damped walls go a long way to provide clean output. Most of all colorations come from the enclosure itself. If you lay your hand on it while it is playing and feel vibrations pounding through the walls of the box then your sub is no longer reproducing the music it has become another driver (in this case a transducer of minimal excursion).

Adding bracing and lining the walls with damping material can do wonders for cleaning it up. However all of that stuff takes up air space. You then have to counter that by adding more damping material like poly fill, fiberglass insulation, open cell foam panels, etc. This slows down the air flow in the box and makes the woofer act as if it is in a larger box.

BH5Space
Black Hole 5 (BH5) does take up space. At least the damping and barrier layers do, but the foam layer counters that and the end result is that the woofer sees about the same air space as it did before. Now BH5 has a damper and a suspended barrier layer. The damper controls the resonance of the panel that it is stuck to as it is a very inert and non-resonant material. It also has a barrier layer suspended in the middle to convert pressure into heat. It is a sound barrier and it helps to keep sound waves from passing from one side to the other. This works great for applications like subwoofers!

For subwoofers, Black Hole 5 is the way to go. You will find that your efforts are well worth the investment, including your time, as your sub will sound cleaner and tighter than you ever thought it could.
