Question regarding which cabinet to build

[bfsjr]

I recently inherited two 414-8B Altec woofers, two 811B horns, two 806-8A compression drivers for the two aforementioned horns, and two N801-8A High Attenuation Divided Networks. These came out of some old either A7 or A8 cabinets.

I would like to build two Model 19 cabinets for these speakers since they are in pristine condition.

Could anyone offer me any advice as to which cabinet I should build for these speakers and crossovers?>

Hmm, the 414 is a 12” driver while the M19, A7, et al, use a 15"/16” 416 series driver, so which do you have?

Yes you need to find out for sure if they are 414's or 416's.. If they are 414's you will need to have duals IMO.Like the 9844 monitors.

I am definitely correct about the speakers so I do have the two 414-8B's, 12" drivers with the 12" speaker. I assumed they had come out of an old A7 cabinet but I'm not absolutely sure of that. I came to that conclusion from what I could find on the internet.

I would appreciate any suggestions you may have about what type of speaker enclosure I could mount my listed speakers and crossovers in.

Since the 414 simply doesn't fit an A7 (or an A8) they came from something else. The could have even been in home made cabs as Altec sold them for that purpose. Each parts could be bought as a separate piece.
I would recommend a sub if you only have one 414 per side.

Something like a 620 might do:

Of course you have to cut appropriate holes for speakers....

[GM]

OK, then the cab alignment usually depends on what sort of performance you’re wanting from it and/or whatever size/shape constraints you have with the largest net internal volume [Vb] normally being the 843 and of course you would use the single driver baffle ‘B’: http://www.lansingheritage.org/image...ure/page11.jpg

So, is either the 620 or this one good enough to suit your needs or…………?

Thanks for the input and I am going with the Malibu 843B cabinets since I have only two of the 414-8B's, one for each cabinet.

You're welcome! Hope you continue the thread showing build updates, etc..

You could always pick up another pair of woofers if that's an option for you.
