Tom, thanks for this design!!! I made up a set of these for one of my girlsfriends daughters. I couldn't stand her listening to music with her cell phone any longer. These are a great little desktop speaker. She loves them!!! The other daughter got a pair of scott's heliums. They are both being enjoyed on a daily basis. For anyone who is worried about output, don't. I had these hooked up to my Peachtree 125 for a couple of weeks before Christmas and they can put out some sound for sure. I was amazed how great they sound. Here are a couple pictures, I was able to sneak the xover into the bottom of the without having to use the frame of the PR but it was a tight squeeze.

They are very similar to the heliums, at least to my ear. I never really did the a/b thing but they both sound great. If memory serves me I think I preferred these at more moderate listening levels. The tweeter on the heliums was a little more relaxed to my ears at the louder end of the spectrum. So for me if I was going to build some for desktop listening I would go with these. I honestly don't think you can go wrong with either though.
As for the finish on the sides, these are just mdf with some rattle can white with a few coat of deft spray lacquer from a can.

How hard did you find installing the tweeter? The first pair I made I used foam and I had to smoosh them in my twisting... real tough. The second time I worked on the Bantam MTM's I used electrical tape I think, much easier. Just wondering how hard it seemed for you.
I'm real glad that you like them. I think in Scott's Helium's they are crossed a little lower, but still pretty high, like around 6k or so... so the ND91 is still doing the majority of the heavy lifting as in my version.

I cut the whole for the tweeter pretty tight and the used some black caulking on the back to make sure they were sealed up good. Could i get them back out? Not easily thats for sure. It definitely tiik some finessing. Thanks again, the girls love them.

You can buy these AMTs on the other 'express' website store. The one with the famous boxer's surname...

Tom... Superb write up.
I have been a ND90-8 user for some time now and have paired them with the ND20FA-6 and AMTs in Sprite type boombox projects. Have also done a 2.1 boombox set up with the ND90-8 and ND20FA-6 doing satellite duties with the ND105-8 acting as the sub.
I recently completed a pair of separates using the ND90-8 with the ND25TA-4. They are in 4.5L boxes. I was worried about the peak at 17KHz with the tweeter. But, it was not an issue after adequate padding down with an L-pad.
I just happend to read about your project. Been wanting to use the ND91-4 in a small set up. Was considering the Heliums. The Bantams look like they can go a bit lower though. One difference will be that I plan to use the AMTs (similar to the ones on the B652 Air).

Man does not live by measurements alone, a little music helps.

Thanks Kenny,
I tried to keep it simple and interject a little humor in it.
It pays to keep a sense of humor when you make as many mistakes as I do.
