As far as the 1.4" compression driver is concerned with regards to my post, to me, affordable would be $150 to $250, preferably closer to the $150 mark, but, if something could be produced to have as good or better SQ than the Radian 951PB, then I think $250 would be nice.

On the other hand. If a proper Be diaphragm could be produced and added to the 1.4" compression driver then I would be ok somewhere in the neighborhood of $250, but, no higher than $375-ish for the compression driver with Be diaphragm already installed..

I've been reading about the system components the past hour or so.
Quite interesting.

I'm not too sure when these were used or if they are still used but here are a few pics of speakers from an IMAX theater.

An interesting thread where even the designer of the speakers shows up.

Even with Erich's pricing, this isn't going to happen.

Erich, if you ever get a few moments, perhaps update the first post with your progress pics and selected components/status?

Lets do a group "imax" theater speaker. Or a (EMAX) speaker ! everyone who wants to get involved throws in 100bucks for parts. Gets built then we make it for diysoundgroup. And everyone that put in 100 gets 100$ off the speaker. Just a thought!

You can just build the SEOS Maximus. I myself would build something smaller and then save up to own a pair of SH64's. IMAX is great visually but I would rather have the IMAX DSL version myself.

Sh64? Danley? Yes defiantly interested in the maximus but depends if he comes out with it in the website and if flatpack and crossover assembly going to be available if not then sentinel 15 ill go with.

I dont believe there will be any flat packs for the Max project. Most likely a design blue print with crossover schematic and possibly completed polars and frequency plots. Humble Hi-Fi did this for years and so have others. I think it is a cool project but hope he keeps his money in smaller designs.

I'm loving the larger design here. I've been so tired of seeing smallish or largish bookshelf type speakers. Or even worse the stuff in the stores that look like you can use them as a toothpick.
Sometimes it's nice to have a speaker with (balls).
...brings back memories of my first speakers I built. [sigh]

I believe the last post was the midrange and the thought was the mass of the 12" mid was or could be causing reflective and or vibration in the mid subenclosure......

So, while Imax speakers are cool and it would be nice to have them all in our video rooms...... This IS where we left off....

I thought that Erich decided to use the B&C 12" mid and a B&C 18" woofer?

I also thought Erich stated the Eminence played nicer than the BC mid. Will have to wait and see. Would be nice to see what he liked so far. If I have not sold my 15's I will have to do a 15" version.

Couple pages back they decided to try an eminence mid as the b&c didn't perform how they would like.

I'm waiting on the 12" Deltalite to be delivered so we can try that out as a midwoofer. The project is nearly completed.

Bill and I did a decent amount of listening with the original design and it just didn't seem right. The compression driver is very good and from the beginning Bill thought the CD just sounded like it needed to be paired with something better than the B&C 12" woofer. The FL-450 wasn't mating well with the woofer for some reason. Highs sounded great, but seemed to stand out because the mids just weren't quite living up to what we thought.

After some more tinkering we decided to switch out the woofer and the Delta 12A was a pretty close fit in the same cut out. Even before reworking the crossover for the new woofer, we could tell it sounded better right off the bat. Lighter cone? No 'wet look' coating? No idea. But it did sound better and blended better. The Maximus needs something pretty nice for the woofer, so I figured the 12" Deltalite should be up to the challenge. I was going to pick that one from the start, but just assumed B&C might be better.

Hoping to get the Deltalite next week and we can rework the speaker with it. That should be the final piece of the puzzle.

"...but seemed to stand out because the mids just weren't quite living up to what we thought."


unless the resonance was figuring into things, it almost sounds like stored energy/inductance was the culprit. I wonder if it is a tradeoff by using the copper coil for big power handling that some midrange detail was sacrificed.

Listen. It's All Good.
