I need help from the brain trust here. I've combed the internet, searched the archives here and made some phone calls all without finding what I think I'm looking for.
In the course of my work I've come across a set of components that look to be Westlake but the more I've studied it things don't quite add up.
Starting as a built-in pair of high power 2-way monitors they had been modified and then abandoned. I'm looking to put them in new cabinets and build new passive crossovers.
Here's what we have:
4 Gauss 4583A 8Ω 15" woofers
2 TAD 4001 16Ω drivers
2 solid oak Westlake Radial horns.
While the original baffles have the circular cutout where you would normally find an L-pad an also the location where a terminal strip once was those had been removed and there is no trace of a passive crossover. So they were converted to bi-amping at some point. Also, while the baffles had T-nuts for mounting the woofers with JBL style clamps, the Gauss woofers were mounted with screws. Lastly, the holes in the mounting mounting flanges for the compression drivers would fit 1/4"-20 screws even though the TAD drivers mount with small M6 screws.
All of that makes me think the original configuration was gutted and replaced at some point. Also, if these were original to the building they were in then they were installed before the TAD drivers were even made.
So I'm looking for a baseline passive design. The gauss specs I can find recommend crossing 800Hz or lower and TAD recommends 600Hz minimum. Enclosure with be ~11 cu. ft. with 2 3X6 ports or equivalent which should give pretty good response to ~36-38Hz.
I had toyed with the notion of adding a midbass driver, but these are not the right woofers for that approach so 2-way it is...
Any thoughts? Input on a bassline 2-way passive network?
