On the Tangband 8", http://www.tb-speaker.com/detail/1208_03/w8-740c.asp would it appear that these would work well in my buddy's VW van? He has a big wooden box under the back seat, if I had to guess I would say that it was about 6 cubic feet or more? It is a storage box, but we put 6x9's into some existing holes, and it has room for a pair of 8's, also. The seat flips up, which gives access to this box, would a layer of foam tape around the edge help? What specs do you need to look at to determine if a sub will work decently free air? I did a few searches, still came up short. Thanks!

If I recall, the Tanbang 8 has very small box requirements and so I think that it wouldn't work well in a free-air application (especially of that volume). Why not make part of the storage box the enclosure?

Looking at the sub's QTS, you could run an AP setup...

Thanks for the info, I thought about doing a box within the box, not a bad idea. AP is not really in the budget, though.

looking at the ts, probobly a small vented would be best, definitley not ib

Thanks for the help, Defro, I think .75 sealed is reommended, 1.2 vented.

Yeah, put it in a sub 1 cube box. I found that out the hard way with my TB.

Get Tb speakers from Speaker City .

as a general rule, subwwofer with a qts of less than.30 will yeild the best results in a vented box or 6th order bandpass, but not sealed and definitley not ib, i,ove the description of teh speaker, magnetic voice coil, nice [img]graemlins/headbang.gif[/img]

I didn't know that you sold them. Defro, thanks for the info, I was wondering what the general rules were, for box design. Chadxton, what kind of a box did you have yours in, did you blow the sub?
