Altec 816; Outstanding Cab Design for approx 80 HZ to 1200 HZ. The 4 I had came with "thin" curved horn sides so I added extra wood and Boat Resin on back side. I loaded Them with EVM 15L Proline. Very good build job on Your new Project. Old School is Real Cool.     VECTORSONICS

I know this is really old but I have a friend that wants a retro system and I think these would be good with a 511B  horn on them some current drivers and a sub that matches them with a slot port on the bottom to match, what i cannot find is the radius of the horn that detail is missing from all the plan I can find. Does anyone have a detailed plan or know the radius, thanks, Mike

We have some of these cabinets, run them 80-250hz loaded with Eminence Delta. Fantastic lo mid section on top of scoops and below Turbosound TSE111 copies.


I find the sound starts to get abit muddy above 250hz. hope that helped

That 816 cab is beautiful... We never saw it's mate though :(
 
I have a question for all; the box handles take up cubic volume; is it an amount of volume that matters or is it negligable? I have seen authentic cabs with and without handles and it struck me it might make a difference.
 
JBL was the speaker of choice in my region when I worked in Rock n Roll production back in Ottawa, Canada during the 80's and 90's; Altec was never on our menu so I didn't obsessively memorize the specs of every Altec component as I did with JBL back in the day. As a result I don't know the difference between the 816a, 816b, 816c and 816VI. (have I listed them correctly?)
 
Could one or more of those variations have been adjusted to accommodate the box or metal bar handles?
 
tv00 mentioned Martin 215's. I remember those back brakers fondly. In the 80's we used martin stacks loaded with JBL. We stacked 215's 6 high and 3 wide per side at medium stadium shows and we used scaffold to stack them higher at largher shows; it took three people to hump number 5 and 6 and when we stacked them higher we had three guys on the ground and two or three in a scaffold on large air filled tires so we could hump them twice and then push the scaffold along to the next stack. We also used Martin 212's for mids and custom boxes for our JBL 2380/2445 highs and 2370/2425 very highs. We also had Martin 115's but they were only rented to customers and the 215's were reserved for our shows.
 
Later we switched to the SR series. It seemed like we could pack a lot more wood into the trucks but they weren't nearly as good as the Martins.
 
Anyway, back on point; I intend to build 816's (to be used as mid/bass but not bass) and I want them to be as road-ready as possible so I want them to have box handles but I also want to be able to sleep at night; I really have to know how much effect those box handles will have on the sound or I'm going to lose sleep over it forever... Hope someone knows.

Sorry, that's a good question!

Hd15 is nice, but i would probably do some kind of straight horn, important is to get the horn mouth to open up wide enough to spread the waves, and then it will get long.

I just got a nice pair of martin audio 215 for just £200 that I'm looking forward to play around with!

I'm not sure I'm the right one to answer this question!-search this page and several others for answers, this site where you are is good for new designs which i would recommend and this site is better for older: http://hornplans.free.fr/plan_site.html

I think the Altec is far too heavy, like most modular boxes are, I have jbl / SA 4512, -they're heavy!
