I have a couple of these WT-644s

[katana2112]

I have 2 1cuft boxes and 2 BFM Autotubas(all empty), would these be any good in either? Any thoughts as to what kind of woofer/subwoofer I can build? Im a woodworking novice but I have all the tools.....Any feedback appreciated.

Perhaps modelling them in winISD would be a good idea?

I expect 1 cuft for a driver like that would be too small, though adding a Linkwitz Transform would get more bass out (at the expense of max.SPL - still, they have enough excursion to go pretty low).

If you have the stuff already, why not try it, experiment with stuffing and things like that?

Hi,

Agree, 1 cu.ft would be good for use in a car ,f-3dB ~ not below 60 Hz but this driver is IMO very well suited for T-TQWT applications :

Ah yes, Hornresp. I still find it amazing that you can (seemingly endlessly) roll out various plans for various drivers, Bjorno. I got a graph out of it. Once.

Anyway, I seem to remember that Logitech uses this woofer (maybe a SVC version) in their Z5500 set-up.

I like the look of the horn on the left I just havent had enought time to figure out the workings of hornresp yet.....
