BH 760 specs or photos
« on: July 31, 2019, 12:43:36 pm »

I am building a pair of BH 760 cabs and have them ready to assemble but I am missing the specs for the cutout in the 1/2" spacer for the driver, and the size of the cutout going into the throat of the horn. I do not have the box available in Kansas City to look at in person. Does anyone have specs or photos they could share?

Hi Matt-

I can't help with the direct question but thought I'd leave you with this bit of Live Audio Board history:  the BH760, IIRC, was the impetus for Tom Danley designing and then giving away the LABsub.

Exactly
 
His idea was to show that an "average" woodworker could build a better performing sub from a popular big name brand, for less money.

According to plans in this thread:
https://forum.speakerplans.com/eaw-bh760_topic21659_page3.html
the 1/2" spacer would have a 278.1mm circle, and the offset horn throat cut out is a 140mm square.
The spacer size depends on the actual driver's surround diameter.
If you were to use longer excursion drivers than the OEM drivers, a 1/2" spacer may not be deep enough to avoid surround damage at Xlim.
