Does anyone know anything about IMAX speakers?

[Woofer]

You can probably source the manual for that amp in order to see how the dipswitches are set. That shall tell what the settings are according to the picture.

And a link - http://www.abamps.net/

Yeh, thanks Lee.
That was mentioned earlier, (but no link tho'), but at the time I'd already spent a hundred plus hours sifting through billions of pages, and I just wished someone would just simply tell me.....
I'm just so exhausted from it all. I'm an old man now, and I just don't have the stamina I used to.

Anyway, enough for today. It's after 3.30am, and I'm off to bed.....

Yes Johan, you just beat me to it. I was about to post that too!

Mmm thanks for the IMAX porn gentlemen, made my day!

Remember, IMAX uses bass management so the subwoofer is matrix created from the main channels. 80hz would be a good spot to start, i can't see 12s playing down that low for dialog

My sentiments also.

Here's what they look like cleaned up! It took some research to find materials and many hours of labor but they are dang sexy..

Looking good. So, you have 4 subs and 4 mid/highs to pressurize a storage locker? How wil you treat those galvanized panels?

[Woofer]

..... all you need now yrrab07 is a truckload of power amps and a 3 phase power distribution board and you're away! LoL
Finally got around to installing them in the studio, and after a bit of tuning, they sound superb, and at any volume be it high or low.
A bit of a problem with a lack of 2.5K, but that's all fixed now with slapping a Klark Teknik parametric across them.
A very nice system and appreciated immensely by all that have heard them so far.

[Woofer]

Well, the story continues......
Just been re-offered the original 3 pairs of power amps (Bryston 7B Mono amps, rebadged as Sonics 800x by IMAX) for $1000 the lot. (yes, that's SIX 7B's at under $170 a piece!)
Wot to do?????

[Lee in Montreal]

Do you really want me to knock you on the back of the head? Come on. Go get them. This is dirt cheap power, and original at that.

Heh heh heh..... Yeh, I needed that Lee.
I'm just waiting for daylight now, so I can finalise the deal, on the amps mentioned (all six), plus another IMAX box and two more subs.
(it's 2.30am right now, so not really a good time to do anything more but wait..... anxiously.)

UDATE:

A reply from Bryston...

"We did indeed manufacture the Sonics 800X for Sonics, who supplied the sound systems for IMAX. The units were roughly equivalent to a 7B NRB, but had a modular input board/rear panel, to allow filtering and other processing specific to the application. Depending on the rear panel module installed, they could be used as a mono or stereo amp.

Some units also had limiters built in to the channels, which is great in a theatre application, but may not be great for home Hi Fi."

[yrrab07]

I'm looking for a place to sell these bad boys! Any suggestions? There are four component speakers and three subs. Picked them up in person from the IMAX Theater. Thanks

[Woofer]

Wow! They look to be in awesome condition.

Maybe you could split it into two separate systems, but obviously one with one sub and the other with two, or you could have two systems with one sub a piece, (it's enough), and sell off the other as a single sub.

Be aware that these subs are going for as little as $300 each, or less, these days.
They only (usually) have an Eminence 18" in them which sell really cheaply on the 'Bay on their own.
Last one I saw went for only around $130.

BTW, which drivers do your hi/mid boxes have? Is there a TAD 2001 for highs in there or something else?

Cheers,
George.

[yrrab07]

Hi George,

Thanks for the suggestion of splitting them up! I am a bit surprised to hear the subs go for so little considering the boxes alone had to cost hundreds to build. The Hi's are driven by a TAD TD2001 with an 8" mid is pushing the larger horn.
