Where do I begin? Acoustic suspension woofers can offer what is termed "tight" or "fast" bass. The tradeoff is that acoustic suspension designs tend not to go as low as bass reflex speakers, certainly not as low as a bass reflex speaker the same size. HOWEVER, acoustic suspension can be boomy. The key is the total Q of the driver in the enclosure. Acoustic suspension speakers can be tuned to be transient perfect (0.5Q) all the way to boomy (just about anything over 1.0Q). The problem you fact is that the required size of the enclosure for your woofers will depend on both its Thiel/Small parameter and the desired Q. If you stick with the box you have, you will be VERY limited in your choice of drivers. You will have to find a driver which works for the desired Q in your existing enclosure. This has nothing to do with the drivers presently in the box.

As for the box, there are materials which can break up the back sound wave to some degree. For damping there are compounds like Black Hole 5. But you will be limited by the box which probably isn't terribly well made.

If you are serious about this, do it right. First, you need to know a lot more about speaker design than you do now. Get Dickason's Loudspeaker Cookbook which is the DIYer bible. All the equations you need are in this book.

Next you have to decide to build your own cabinet or have someone build it for you. Acoustic suspension speakers are some of the easiest cabinets to design. This way you can build the cabinet for the woofer you select, not the other way around.

Hope this helps.
