"MoZi" A Sealed 2 way design

[Ironman129]

I am working with Pete on a sealed two way using a rear mounted AST2560 and the Satori MW16P. The baffle was CNC cut and once Pete confirms that it will work well for the AST2560, then I will upload dxf and 3D printing file for others to use. I am excited for this pairing. I prefer sealed compact enclosures that can almost disappear behind the sound stage. Pete is working on the XO now and looking forward to his feedback on how they sound.

Looks nice and should sound great

Great combo!

Should be able to get some testing done this weekend. Still trying to come up with a method of mounting the tweeters that combines a small chamber to isolate the back of the tweeter from the enclosure pressure. Got some ideas . . .

Pete,

I saw someone else (can't find the thread now) that did a rear mount with a waveguide in natural wood and have the mounting holes go through the front of the guide. I think that was what you were trying to explain about an easy way to mount it. I wonder if you you drilled a small pilot hole all the way through from the rear and then did a countersink from the front if that would work.

Why put holes through a nice baffle? Surly you can use some sort of rear mounting scheme

[Pete Schumacher]

Yeah, that’s exactly what I had in mind. But it needs to incorporate a sealed chamber since the back of the tweeter is just a piece of felt.

I had just been wondering about this driver pairing. I look forward to reading about your results! Looks pretty great so far! Sent from my XT1710-02 using Tapatalk

CNC sure makes things EASY and faster turn around.. This hand sh!t is sure getting old ..ARE YOU USING THE 8 ohm Satori or 4 ? Really love the wave guide look with ribbons

I've got two 4 Ohm and two 8 Ohm Satoris on hand. The 4s will go be wired in series for the center channel.

OK , Series makes sense.. I have 4 now in a two way that's being worked on and its already a sensitive driver .. The 8 is what most use as its easier to work with but not sure it sounds the same ! I will be more informed on the 4 real soon. Tweeter I am using is great BUT LONG DISCONTINUED..

Pete,

Don't know if this would help or not. I am not very good at freehand with a router, but you could use this to press fit the tweeter to the back of the baffle and put a chamber on back. 5"w x 6.25" tall. I think they could even be bolted on from the front without going through the waveguide.

[Pete Schumacher]

I built a little box that comes an inch or so above the back of the tweeter. I'll put some stuffing in that chamber too. Remember, that felt backing will not keep the woofer pressure away from the AMT, so the back of the AMT needs to be in an enclosure.

I'll clamp the little box to the back of the baffle similar to what 6thplanet shows above.

I like your solution too. It just needs a little box over the back of the tweeter to complete it. And only a couple inches deep will be fine.

Pete, does the size of the back chamber have any effect good or bad. I know you are supposed to fill the chamber with something but I did not know if the size
of the chamber mattered.

With a tweeter and the very short wavelengths involved, I doubt you'd need much more than an inch or two behind the diaphragm as long as its well damped. Look at dome tweeters and their rear chambers for example.
