Oh, I thought they were poly-fill batts. This is synthetic material though, and not a natural material like cotton, right? Do you know what material it is?
Spent the day setting up the MTM's. Unbelievable sound really, now that said the sweet spot is pretty tight and had to tweak the angle a few times.
Using the passive xo's here, they are not in the boxes and on the rack btw.
What crazy about the Anarchy IMO, is the sub-woofer like, chugging bass and delightful mid-range.

Update: gave up on the short bases, these Star Wars Legs stands work better.
Tweeter is set at 38" center. The mtm pair was a weekend project (using high grade mdf) Thinking where to go from here would be a BB pair.
Adding a pic of the TMM's, which was from another project, but seem to work fine with the TMM rendition xo.
Third pic is another speaker fan

Sneak-preview
Wife asked the other day, what CD is playing????
It wasn't the CD - it's the new MTM's. The sound just fills the room with a really nice sound stage.
Good enough for me, so started a BB pair.
Made the port smaller: 5/8" x 7" which should move the Fs up a bit - high 30's
These cabinets are 8-3/4" wide btw.
One side is not glued, just clamped so can still change port length if necessary.

I am looking to build a version of these in mtm set up. i had a few questions and request. First is there any way i can get a picture of the crossover built and a parts list? Has anyone tried a different tweeter? I want to use the ss discovery 8320 or /8330. i have both. I know that would change the crossover design so i am just wondering. if not i would stick with the dayton. Do you guys feel 1cu ft is the sweet spot for the cabinet? I was told 1.6cu ft for 2 anarchy was best to reach down to about 30hz. Based on what i am reading in this thread i would be giving up some of my upper mids with a larger box.
The volume of the cabinets? Go with the 8.25"w x 25" tall by 13" deep.
We do like the taller boxes on post 44 because of the 30hz bass, but I'd stick with the 1.09 cubic feet, tuned 36hz - 38hz. Loving the front port, so highly recommend that also.
The tweeter? The Dayton is a 1-1/8" dome, so it is designed to go low, which makes sense given the versatility (and limitations) of the woofers.
Here's a parts list for the woofer side:

Made an easy/fast/accurate 4 piece tweeter template out of scrap, the steps are:
Cut round hole to the 4-3/32" size, mark and cut carefully and then glue it back together with 2 square boards as shown. Now I did say it was easy
The upper circle is the standard 4-3/32".
The BB boxes are turning out well, no miters except the 3/4" x 3/4" wood edges. Mark the wood grain with arrows and orientate the grain so there won't be any tear-out when rounding over with router.
btw - the woofers are 12" CTC.

I am not sure if i am reading this right but it seems that the dcr on both is missing. Was that done on purpose?
And i understand WHY the dayton was used. my question was has anyone tried any other tweeters? Both ss 8330s do the same thing but better. I have used all three only(and a few more i have the supremos in there now.) in a Truck so i know that is different but the daytons never handled the low crossover points(never below 1700) and spl the scans did and sound good doing it. To me the daytons dont sound that good when pushed.
Last if i wanted to split the port in half and have one on each side would that cause any issues?
My speakers will be laying flat but at eye level.
Other tweeters with the Anarchy, sure, but don't know any with a ss 8330

New tweeter here? That's a tough one; maybe pick up a mini crossover and try it active first.
Two ports, yes, this driver was already loaded in WindIsd so made a few clicks:
Laying a pair horizontal? That may never work actually, I guess you could try it.

best and cheapest place to get a mini crossover?
Amazon:Amazon.com: rolls SX45 Tiny Stereo 2 Way Crossover: Musical Instruments
You'll want to check the phase with a mic, which can be done with a computer mic and a free download.
However, if you have the cash pick up a Dayton or a mini UMlK-1

Do you have the dimensions to build a box with two ports for the anarchys? cut sheet or any thing like that?
cheebs maybe this is enough to get you going.
MDF build? Best to start with a side on the table, cut to the size you want. Cut the second/opposite side slightly larger so it can be trimmed with router and/or sanding as needed. Be careful about routering around the slot vents, easy to forget they are there and gouge the work piece.

I know, they're just boxes, but still fun to do.
The advantages of MTM's vs. one, more expensive woofer.
Correcting the inherent lobe tilting of a typical mid-tweeter configuration.
Two woofers share 1 box and XO
XO woofer coil will most likely be smaller (less money and work better)

I didn't started to build yet as i am still reading but a question i have is doesn't getting the woofer closer together work better?
As i am measuring out the cuts i realized a few things. the ports are a half inch wide on each side??? and the height is 8 inches in total including top and bottom???
Woofers closer together work better, not really depends on the design.
The ports on post 55, yes 1/2". Have 4" x 4" spacers (aprox.) ready for layout, building and assembly.
The final width is 8-3/4" but just work to the "rips". There would be over 8 feet of 7-1/4" rips per speaker. It's important to cut the pieces at the same time and get them as uniform as possible.
Here's a few pics, including the xo. Don't look too close, it's been taken it apart and put back together a few times.
Oh the BB boxes are awesome, the few small mods and better wood did make a difference

That works i wasn't sure but i got you. I don't see the speaker input on the crossover.
