I once got the contract to design and install the sound system for an IMax theater in the Minneapolis area. I used a quatity of 7 JBL 4435 studio monitors and 6 custom JBL loaded 18" subwoofers. The sound was QUITE good. The 44 series was the replacement for the 43 series. My front speakers in my HT system are JBL 4430's.

Which IMAX is that? Valleyfair, Science Museum (this one is friggin insane), Minnesota Zoo?

Just curious ;)

That was Valleyfair. I designed the system that they used when it was first built. I don't know if they have changed anything since back then. I believe it was the only IMax theater sound system designed out of IMax control up to that time. The IMax whigs liked it very much when they came out to check it out. I've got some pix of it around here somewhere. When I get some time I'll scan them and upload.

Great pics! Thanks for posting; they should be on a website somewhere (aside from here), so that folks interested in IMax could see them.

I always enjoy seeing the "behind the scenes", especially when it comes to audio/video gear.

We talked about my all A/D/S speaker setup in the vinyl thread a while back, Richard. And the Nakamichi ZX-9 and Denon DP-72L 'table, and Belles Research amp and preamp that I bought on accomodation back in the day. Man, it helps to work amongst your toys! I still have all of 'em!

Ah, yes. YOu hit upon my method of picking up all this good stuff when I was in the business. The 4430's are actually my second pair. I bought a pair, used them for a year, sold them at a profit and bought another pair. My boss made me stop doing that though. :( My rear speakers were purchased at the CES show years ago as part of an opening order for Monitor Audio. THOSE things sound great and would be a fantastic front speaker in an HT system. Of course, with the JBL's I need no subwoofer.

That was one of the fun projects that got alot of public notice at the time. ;)

Very cool pictures Richard, I have never been to the one at Valleyfair, but have passed by it many times ;)

I love seeing behind the scenes!

Amazing the difference between that and the one at the Science Museum downtown which is very new (also an Omni vs. regular IMAX)...quite a difference in technology over the years!

Nah, I used a level to install it. It's straight. I suspect it's because of the camera location that it looks that way. ;)

I have been to the Science Museum several times and enjoyed the shows there, but, it appears that they have moved to a new location since I visited. I guess the new place has a "convertable screen" that can be used as a dome or a flat screen. Sounds interesting to me. I'll have to visit the next time I head in that direction. If I recall correctly, the old science museum IMax screen actually predates the one at Valleyfair, but the old one was a fixed dome screen.

I went to that IMax back in the mid-80's. I don't remember what we saw, but I'm pretty sure it was my first time at an IMax. Maybe some kind of river rafting adventure, or at least that was part of it.

The first film shown there was "To Fly" http://www.bigmoviez...ex.html?uniq=72 A couple of people actually got sick in the place during the film. :barf: They say that this was partially due to the change in temperature going from a HOT Minnesota afternoon to a VERY air conditioned auditorium and the disorientation caused by the motion in the film.

Yup, the new one is very neat, the omni dome comes down like a helmet visor over the audience (and covers the standard projection screen). Amazing to see.

They also have a nice intro that shows off some of the technology, and after or before the show you can of course go and see the projection room like most science museums do with their imax theaters.

"To Fly" was the first IMax I ever saw, and it was absolutely amazing. It was about 1980 at the then-Marriott's "Great America" theme park in Santa Clara, CA. At the time, it was the only IMax in California, and only 2nd or 3rd in the world.

I'd love to see it again sometime.

Those are mere babies compared to the Polk SDA SRS models from the late 80's, early 90's. At the time, some of the best speakers I had ever heard.


Yeah, I was going to mention the Polk SDAs.
