Hello Lads,
well this long journey is almost at an end. I need to install some more of the wool felt insulation and finish mounting the 416B's to the front panel

Which brings up the question of...

Hello,
I am using the type 50 Jabo horn which is smaller than the type 55. my horns are 21 inches in diameter.
They were a tad small on my old Altec VOT speakers, but are perfect in these Onkens...

Hello,
Thanks for the praise.
I would have had to ship Baltic Birch in from the East, and that would have put it over $375.00 a sheet. as it is the Apple ply was $175.00 here.

The HF are Altec...

Hello Lads,
For you still watching this thread, I wanted to update you.
The cabinets are almost done, and wanted to share some photos and some thoughts.

I elected to have a cabinet maker build...

John,
That's the conclusion I came to. I set the B's up with the horns and the xovers with a blanket around the woofer, and it sounds great like this, can't wait to get the boxes built.
I just need...

Thanks,
After a lot of footwork and advisement, I am now committed to the 1" Baltic Birch plywood for the cabinets, and I am trying to find the 10 MM wool felt insulation.
I am still trying to...

Hello Lads,
Thanks for the information.
I was able to get a reply from Manuel that did the photo build site at Ispra.Net - Alex Patak Audio

He reports that his build was from 25MM "phenolic...

Stephane
Thank you, but it appears you are using a totally different design with your speakers, you have a double wall with felt between the wall. I am building an original Onken for the Altec 416B...

Thanks Lads,
I guess I will have to bite the bullet on this, as this is going to wind up at around $1200 for wood and labor, might as well spen the other $250.0 for the 1" birch.

So onto...

Stefan,
Thank you,
I have all of them and more, but they do not address the issues I am asking about.
As per insulation other than lamb's felt, 3/4" versus 1" thick plywoof etc.
Thank you,...

Hello Lads,
I had posted before on Altec 515B cabinets, but since then I have changed directions, as I came into a pristine pair of Altec 416B woofers, and have decided on building a pair of full...

Hello,
Thanks for the reply's. These cabinets are loaded with 515B Lows, and came with 288C HF drivers with 311-60 horns.

I have been told they are A-5's by some on this board in another photo,...

Hello Lads,
Can some of you make suggestions for cabinets for the Altec 515B woofer? I have a pair of A5's with Jabo conical horns, and Behringer crossovers running right now, they sound great, but...

Dear Dave,
Thanks for the reply, but I may not have been clear. I did not mean to cut the cabinet in two. I meant to make a separation of the upper and lower portions of the box from inside the box....

Hello,
I thought about that also, the kind of sound deadening that is used as undercoatings. The problem I think, if one is to stick with the original design of the box, and to now use it in a home...

Were not talking Physics lab, which is what annoys me about some postings, science is as much about physical perception as it is about demonstrable and quantifiable, effect. We are talking about end...

Hello Lads,
Thanks for th input, ireegardless to the first response, I had a bunch of foam sheets here that I use for packing gear to sell.
I stuffed the insides of the flares, and found a full 50...

Hello Lads,
I joined the big stupid speaker club, and now own a pair of Altec A7 VOT speakers
My local college got some money in their budget and upgraded their sound system. They auction off all...

Well, after looking at what is going on in my L100, I am beginiining to think this is a wiring problem more than anything, as what I can see without pulling the crossovers out, it does not look like...

Hello again,
well I got he woofer out. the guy before me used those claw based nuts, and they were just spinning around. I had to pry up each corner with pressure and then back off the screws.
I...

Hello,
I was able to swap out the mid range speakers to the good speakers, and the mids are working. So that puts me back to the crossovers. Is there a way to check these?

Also, I went to pull...

WOW, talk about fast. You guys are great. Now can you tell me how do I check the L pads, and are these replaceable, and are they available to replace?

Thanks again,

DOnald Bowman

Hello all,
I am a new kid. I hope you can help with a L100 problem. I have three sets of L100's, two work fine, but the third, I bought at an estate sale, are gettinn no sound from both the tweeters...
