How do the Neo's compare to domes for dynamic higher SPL output?

I have not reached a limit, so it is hard to say. And power handling with the Neo's crossed over properly is quite high.

Danny, how much would it cost for all of the parts including crossovers to build the Mockingbird line arrays?

I'm sure you could use counter top material rather than aluminum and save a ton of money.  Of course the legs would have to be made out of something else. Then it would still be thin enough not to cause the problems you were talking about with a thicker material.

I'm still dreaming about these in my room one day.

Hey, a guy can dream can't he?

Those speakers had wood baffles.

To make them again would require that I have more of the woofers made.

The Super 7s MMTMM array seems like a more realistic DIY option, no?

Well all the drivers are still in production. It is just a matter of constructing a front baffle with the tweeter waveguide. Less expensive also.

Just to clarify, are you interested in the Mockingbird LS-X with the Neo8's tweeters and cone woofers line array or the Serenity Neo3/Neo10 style line array?   

The Serenity Super-7's use the Neo3/Neo10 drivers like the Serenity line array.

I measured and tested Jay's latest baffles for them a few weeks ago. It is amazing how much effect the baffle can have on them.

I'm going to follow up that last post with a Super-7 baffle update.

Here are the old baffles.



The wave guide for the tweeter had to jot out from the baffle to create a smooth tweeter response. The Neo 10's were also flush mounted from the front.

The new baffles allowed all the drivers to be rear mounted and was to do away with the wave guide for the tweeter sticking out there.

See new baffle pics:





The Neo 10's loved the new mounting. The response was un-effected by the rear mounting and was smooth as glass.

The tweeters though.... Agh.

So I blocked off the Neo 10 holes with card board and the lower ones with a block of Stryofoam.



Now check this out.

The green line is the tweeter response with the cardboard over the upper Neo 10 holes and the Styrofoam over the lower ones. Looks great huh!

The purple line is with all four drivers blocked off with card board.

And the red line is with the Neo 10's mounted. Dang it! Picky little drivers...



The tweeters response does not like the in and out reflections of the Neo 10's inset from the rear mounting.

We could front mount the Neo 10's, but then they won't be aligned front to back. It will change the driver offset. I don't like that idea. Or we can go back to the more complex original baffle design. Or something.... I am still thinking on that one.

Another update...

Jay sent me these baffles.



Then I modified the tweeter wave guide.



And I played with the short side wing a bit.

The response looks excellent.

Here are the measured responses with a second order slope.



And for the first time I was able to use a first order slope with these drivers. I have never been able to do that before.



So lots of promise on this one.

Okay, I was thinking about the aluminum speakers you made for another company I guess. Those are so cool looking and I know the people who heard them were blown away. Sorry for the OT post.

Looks great with the updated waveguide!

And compared to the Serenity version MUCH more affordable! Nice work Danny/Jay  :thumb:

That was a Serenity product, and yes it was outstanding.

Aluminum was the best material for the job. It was just pricey. We are still looking into lower cost possibilities of reproducing that design.

I am looking forward to seeing what you have to say about first order crossovers. They have some interesting advantages vs potential issues. Good luck!

Do you have an idea of driver cost and crossover parts cost? I don't recall what drivers were in that design.

Hey Greg
16 Heo 3's per  speaker /  6 Neo 10's per speaker IIRC.
