Danny,

I have had the kit sitting for way too long, and with all the other projects, I may not be able to get the cabinets done anytime soon. Is there a source that can be used for cabinets?

Hope all is well!

There are some Parts Express .5 cubic foot boxes that can be used with the X-LS kits.

There are also a couple of guys out there that will cut you a flat pack that you can glue together or they can make you a pair of cabinets.

Shoot me an e-mail and I'll forward your info over to those guys.

Yep, simplified version in the plans. That works.
Great. Thanks!

That isn't what your drawing shows. I braced per it's instructions. Is that now correct?

I already have the stiffeners in the corners and the square stiffener spanning across the middle of the sides. That seemed to me to be enough to dampen the two, relatively small sides. Where else do you recommend adding the dowles? I assume you know I made the small box, not the large, floor standing one.
Corner braces are not really needed. The least resonant part of the box is in the corners.

Here is a pic of the prototype boxes.

Adding another layer of MDF would be way too much of a pain. I may invest in some of your liner product to see if that helps. I will do the radius, at least enough to get rid for the inner edge. I'm very impressed with the sound just as they are now. They sound much bigger, and certainly much more expensive, than they are. I've photographed the construction process and will post a thread on that when I have time. I spent about $200 total on the pair and they sound better than most $1000 systems I've heard. Certainly better than any reasonably priced bookshelf speakers. They will get loud, but won't go rock concert loud. But gee, what do you expect from a speaker that size? Plenty of DB for most living rooms and certainly most apartments.
Okay, cut some bracing using dowel rods to stiffen up the panels then line them with a sheet of No Rez and that will help a lot.

And I am glad you like them. They really are over achievers.

I've constructed the enclosure using 1/2" Hardwood Ply instead of 3/4" MDF. You show a 3/8 internal radius on the midrange transducer mounting hole. With only 1/2" thick material, would that internal radius still be necessary? Also, how do you think the 1/2" hardwood vs the 3/4" MDF would affect the sound?
The hardwood will be very resonant compared to MDF. And being an even thinner material will make it worse. I'd add another layer using 1/2" MDF.

And if the inside edge doesn't have the radius then it will adversely effect the response. The edge diffraction will add a little bump around 1kHz.
