I have a beuatiful pair of 416-8A woofers and need guidance for finding or building the proper enclosure.
JBL 4507, QSC 152i waveguide, B&C DE250 HF driver, and Zilch's Z19 crossover....
ZILCH-
you have replied to a post from my brother (amphead4) at audiokarma. he lays out my dilemma and equipment. i am very willing to follow your expertise. i can sell off the tweets, the 811s with the 808a drivers to partially finance the project. I cannot find the QSC 152i waveguides or the cab plans.
Thanks for your help.
I have purchased the waveguides you suggested from QSC.
Keyword "4507" or "4647" will turn up dimensions, possibly both here and on AK. There have been a couple of builds, but most have found them used, often with 2225H woofers in them, which may be used as-is or reconed to 2234/5H.
The factory vinyl can be removed with an iron and aluminum foil -- it just kinda shrivels up and off -- and they may then be refinished or veneered. There's a small (1/2"?) recess in the front to accept a grille, and the same recess at the rear.
152i will fit in the available space on the stock baffle, as I recall, but confirm. I'll have to unpile a bunch of stuff here to verify that myself. It may also be necessary to relocate the 2x4 crossbrace inside to clear the waveguide; nobody's checked that yet....
...more often with 2225Hoften with 2425H woofers in them
Are those 416's for sale ?

No, I am sorry they are not for sale. i have a buddy that's house is full of horns, drivers and coned speakers. if you tell me exactly what you are looking for i can see if he has them.
Mr. Zilch-
I have been looking for technical data for the 152i waveguides have been unsuccessful. If you have the polar patterns, i would love to see them.
Thank you to all.
I'll send you a PM
