Default typo

oh I've been busy.....check em out.
A pair of Fostex 125wks - aprox $120.
New sub box - aprox $40.
The sound is very, very nice.

Now I do need to rebuild the test sub box shown, I was going to go with the keystone shape, PR in the back.

This design has a 1.75db rise at 34hz, according to computer modeling. Now if there was a fellow that was wizard in WinISD, I'd sure like to know if I should go with a slightly bigger box. (existing box 1.16cf, tuned at 33hz)

Dayton 10" PR (not on sale now)
FS 20Hz
Vas 3.88
Qms 2.50
Cms .67 mm/N
Rms 4.89 kg/s
Sd 340 sq. cm
xmax 10mm

You really should learn Hornresp. Those little drivers work well in a small TH.

rouges? Did you mean Redcoats? They were 17th century. Or did you mean ruddy complexioned rogues?

The 8” speaker baffle board would have to be “behind” the 9” outside board.

Also, was considering using Ύ” mdf for the 20” x 24-3/4” sides. The 9” boards would be need to be ½” wider.

Looks like fun, thanks.

Oh Dough,
You are a Doug right?

Really? Whatever keeps the OCD twitch at bay man.

If you think about it the sides are braced every 3"-7", so 1/2" material is more than adequate IMO. You could always build in ply, but no need really. I'd save the good stuff for something down the line once you get a handle on what you want from a TH.

If you get your handle changed it should be Verdana:
HTML Code:

I Just bought 4 of these because of this thread, I would love to see someone design a TH for these, I saw the pictures posted of one using 2 of these, but maybe we can designate a thread for this on its own... The only TH I have built is JBells ss15, I have 4 of them, I would love to make some of these for smaller home parties.

1-40Hz dual driver TH at full output with these drivers is roughly what you get out of a SS15 with a few watts. Why not build the jbell bass sticks with the 55-2421 for a small rig?
