50 bucks each doesn't seem that expensive to me. $134 the pair includes shipping. Thanks for doing the sim for this one I think it might be good. I have a pair coming I'll let you know. Jim G.

Fool! My apologies; I didn't see that it was the price for a pair, not singles, and inc. P&P. What's happening to my eyes? That makes it a very interesting option, and I look forward to hearing your impressions.

Best regards
Scott

As per a request for the neophone, here's one.
Line length 128in.
Zdriver 25.75in
Sm (or Sl if you are so inclined) 55in^2.

I'd like to think this driver is a good one, though I doubt we'll know until someone gives it a whirl. Expensive risk. The specs are nice though, which is a good start.

Cheers
Scott

PS, Greg -how are you doing it in the BLH sheet? I'm assuming set a tapered CC from So to the driver centre point, and the throat as the same area as the driver end?

S.

Greets!

Yeah, I hate it when work keeps me from doing the important things in life.

Greets!

Fs is too high for a BIB, it puts the 3rd harmonic dip up where it will be too obvious sounding, so a horn is the only suitable high gain cab IMO.

Greets!

Looking forward to a review since I'm not up for much woodworking anymore.

Gees! You must have given Lady Luck a really good time to find all these goodies!

Yeah, with only a nominal ~91 dB above the cab's passband, 1.5 W won't get the job.

Default BIB question: sm for radio shack 40-1285D

It's 11:30, and I'm overtired - am I reading the mouth area correctly :

330 in ^2 ?

would that be about a foot and a half square?

must go to sleep . . .

thanks guys

Greets!

Sleep? What's that? - Insomniac since ~1950

Yep, correctomundo, though for the horn's expansion to be technically ~correct, you can't use a square mouth.

d1 = SQRT(330*SQRT(2)) = ~21.61"
d2 = 330/~21.61 = ~15.28"
or can be done by using the reciprocal of SQRT(2):
d2 = 1/SQRT(2)*~21.6 = ~15.28"
