I can only say what I've done to my Altec project (416/511/802D). The results have been spectacular.

I can only say what I've done to my Altec project (416/511/802D). The results have been spectacular.

My homemade Altec system. Cabinets built from minimum 1.5" thick MDF and covered with striped mahogany veneer. 416 woofers; 511 horn lens; 802D drivers; Beyma slot supertweeters; custom built...
Those are some nice-looking speakers.
And I would second Dave's suggestion about swapping out those 811B horns (rated for 800Hz crossover) for the 511B horns (rated for 500Hz crossover). These...
Welcome back, Mr. Earl. Hope you had a nice trip.

SpeakerDave has it exactly right - these are not factory-made cabinets. The veneer, while quite nice, is not up to the standards of the factory units. That, and the other points you've already noted,...
That cab is beautiful. I think I know the answer to all your questions, but I'll wait for the real experts - where are you, Earl? - to chime in.

Where are you located? Great Plains Audio in Oklahoma City is a first rate Altec/JBL service center. Don't bother trying to email them - calling is the only way you will contact them. Talk to Bill.

HF, that is one of the clearest and most concise explanations I've read about horn mouth area, resonant frequencies, crossover frequencies and other technicalities. I'm bookmarking this post for...
I was wondering about this project, too.
Man, those orange grills would look great!

I don't know the answer to your question, but I'll bet you can test the presence of hidden screws behind the foilcal by using a small magnet pickup tool. Probe across the foilcal, and the magnet...
Hi Stew!
Your first post is a real doozy, I must say. What a discovery you've made.
Honestly, you will get a LOT more information on Altec systems and drivers by posting your questions to the...
Those cabinets are just beautiful, my man! JBL blue is always a standout color, of course, but the veneers are so nice. Kudos on a great job of cabinet building!
Question: are you gluing two...
There seems to be some renewed interest in the A8s in general, and in the 32B horns in particular. I've read a number of articles by folks that much prefer the 32Bs over the 511 and 811 horns. It's...
Me, too! It's a lot of fun watching you build your system and constructing all the cabinets and horns by yourself. Excellent work!
I'm not a JBL user, so I have no idea as to the answer to this...
I wonder why one of your 416s has an aluminum cap? Have you checked the printing on the back of the cones to make sure that they are both original cones? I think the number should be 21184.
I...
That's true in my area, as well. JBL seems to have the club and church markets well in hand. My church has a JBL line array/subs system that is just killer.

True. Big boxes with big woofers sound open, uninhibited, and realistic to my ears. Yes, I've heard some very impressive small speakers, but none that come close to the natural and enveloping...
Good for you, Ed! I don't understand how what you did made the difference, but it did, and that's all that matters. Strange things happen in electronics to me, too, but because I'm an uneducated oaf!...
I'm a fan of corner cabs, and your's looks quite nice. Great price, too!

Baffle step losses, I think.

MCM Fan -
Your crossover build pictured above is very attractive and neat looking. You did a beautiful job. I really like the "frame" you built around the upright inductor. Very nice work!

Hi Ed.
Most folks just use the Dayton Audio poly caps from Parts Express. Last year I ran across a post by a fellow who used the Dayton caps to rebuild his M19 crossovers and posted the process. I...
What RDGrimes said. Physical alignment is nothing more than what the name implies: the various drivers are positioned on the cabinet so that their voice coils/diaphragms are vertically aligned along...
Oh, my! Those L200T3s are some homely-looking rascals, aren't they? Nice components, though. If they were mine, I'd have to build some enclosures worthy of the name. :)
GeeDeeEmm
From the...
I'd just build some 4412-type enclosures with enough extra depth, width, and height to equal the L100T's volume. I'll bet you could do enough adjustment to make them look very similar yet still...
