24 speakers in each cabinet?

what are these?

Homebrew from someone who got plans for a ''sweet sixteen" array and didn't stop in time?

 

[SleeperSupra]

Wow! Great deal!

 

[mars_volta]

Organ?

 

[nfafan]

That's kewl. Gives me an idea for all those HTIAB speakers I've inherited...

 

[Gazdatronik]

Another vote here for the sweet 24. Most of the drivers are the same ones recommended in the article.

 

[damacman]

Really for that kinda money, I'd be tempted to take 'em home ...

 

[nolasally]

The original kabuki please stand up!!

Organ?

Without question they are organ tone cabinets.

 

[swechsler]

This seems the most likely. Note that there are at least two different types of drivers in there.

Not really relevant but seeing that photo reminded me of something. A long time ago, there was a club/bar that sprung up near where I lived that was a bit off the beaten path. It was near a go-cart track. It featured live music but the house PA involved 16 (I think) 6 X 9 car speakers in each of the slapped together cabinets. It sounded absolutely god awful. That club might have only lasted a couple of months and probably not just because they had a really bad sound system.

I'd jump on those just for the cabinets.

Exactly. I've got access to a pair of "real" Sweet Sixteens. 16 mediocre drivers that don't go low, and don't go high. It was thought that because you had a bunch, they'd somehow come about and do what was required. Approximately 2 years after the launch of the kits and design so you could make your own, they published a follow-up article that stated they were wrong. A complete sonic disaster.

I am more curious in the way so many speakers are wired in series. How do they justify that with the amp needs?
even if they are only 2 ohms each, that would seem to be a huge load for the amp.

Instruct me, please!

 

[Mike Stehr]

If I recall, the impedance goes up when wired in series.
I would take a big guess and would think the drivers are wired in a combination of series and parallel.

I'm assuming just like batteries, groupings of series and parallel to keep the impedance within a usable range.

Hopefully someone on AK has a few hundred to blow on them, a lot of space and a receiver they want to put at risk. Not me LOL

Maybe they are not wired for conventional home use, but for some device such as an organ.

True, they could be 600 ohms or whatever. But just as likely they are 8 ohm and wired in series/parallel. It works well in squares: put 3 drivers in series, then put 3 of those strings in parallel, and you have 9 drivers with a total impedance the same as a single driver, but with 9x the power handling capability. Works the same with 4x4 or 5x5. You actually get a magical boost in output db from multiple drivers, too.
