Thanks, I do happen to have 8 identical woofers. Two pairs are in Ansonica speakers, but not for long; I'll measure before removing them.
Parts are showing up; both coils for the mock up were undersized (DC resistance), so we can compare that also.

Parts are in; meets all specifications.
The only question was the 20w resistor, not sure that's large enough.
Might just make two smaller boards for each, which seems easier, neater.

Hong,
Looking good! Clicked on measure and recorded over the old xo by mistake, but line is closer to flat.
Blue line - Rendition
Red line - Rendition with tweeter reversed
Green line - similar speaker using Anarchy drivers called Ansonica, a 2.5 way.

Good job Doug. In terms of the resistor, I can tell you that I put the Renditions through hours of loud listening without the resistor even feeling warm. My crossover was externally mounted, so I can attest to that.

These are a big hit here: plenty for everyone, great sound stage, great bass and for a MTM they have a generous listening field , sit/stand/walk around, they do fine.
There was too much fill in my boxes, so that was a quick fix, turns out don't really need much. Padded the tweeter down with a slightly larger resistor - until these
new parts are broken in.

Using the white boxes for the last couple of weeks, 90% of the time the sound is fascinating, the other 10% there's just too much bass; but that said the white boxes are much larger than the 1.1ft3 Renditions.
FYI, Anarchy woofer does produce some very interesting, accurate, bass notes.
There's another set of boxes here with very close dimensions to the original TMM on post #1 - well that is if the bottom is off (or add an internal divider) with a new 2.5" round port installed.

Spent the day as hoped; replaced the tweeters, made new xo's and moved everything around.
These new TMM's are not Renditions, only boxes that are very close to the original plans.
However another great success!!! The bass is tighter and now better/clearer midrange - couldn't be happier 😀

Some new test results for the white mtm's.
I had forgotten that the Y cable from sound card to amp was 25' - and it was wired backwards. So some quick fixes with a new cable and now seeing better results.
Also changed the series tweeter resistor to 3.3ohm; dialed-in by ear but also looks good on paper.

Having good luck with the Anarchy's. The last experiment which was easy/fast put 4 of them in the white box (post 4), no tweeter/xo and just using it for a sub woofer. It's working great and sails past 30hz no problem. Wired them parallel, then series for a single 8 ohm load, getting plenty of bass with minimal cone movement
The tall box is a "double" with 4 slot ports, 9" x .75" x 18" btw.
Going back to the OP, I would like a pair of Renditions, with front port(s), so thinking something like this:

Hi,
Sorry for the offtopic. I have a hard time finding the woofers reffered to in this thread. Could someone help me with a link to a webshop or datasheet.
Thanks,
Bas

Anarchy? A multi purpose speaker, used in cars, HiFi and HT.
Two of them in 1.0cf box will provide plenty of bass, for an HT sub-woofer use plate amp with a low end boost.

This has been on the back burner for a while, a D'Appolito configuration.
Only have one passive board right now, but that's enough to test.
O.D. of box is 9"
A shout out for Sound Group!!! They shipped fast, the transaction was less than a week 😀

Finished the MTM(s), well two coats of primer.
Compared the TMM to the MTM using a small active xo.
Very similar results:

Why so much fill for a ported box? Is this standard practice or is it just for this particular application?
What is that lining material on the back and top inner wall?

Norm, Didn't have much time to test them, but I didn't hear much difference between the the two. The bass may be a little stronger with the TMM vs. the MTM, but IDK.
Keith, The fill is not the typical heavy (expensive) damping material, it's from the craft store; super cheap. The ploy is to fill the box loosely and evenly. Need to be careful though, they don't always have this cotton-type stuffing and poly-fill won't work at all.
Did you happen to see the white filter material at the port? That keeps fill out of the port.
The red felt? That was on sale at the same fabric store, something like $2.99 a yard, but they only had two colors, pink and red.
