By the summer there will likely be a whole family.

We will use a121 to work on narrowing down optimal CC sizes for various drivers and with a suitable pair of inexpensive drivers (ie 40-1197 or vintage driver) will go off real cheap to someone on a really tight budget (and it won't be the 1st or last to do that)

I will build these! Cool design,shape and size, perfect for the room and system I have in mind. Will you have plans for both metric and SAE? I`ve got enough 18MM baltic birch left over from the Fostex FE206ESR`s that I will have finished by the week-end, so we`re ready to get cutting. This is a great hobby.

Our material here is all metric. The CAD software (VectorWorks) will spew out both English & metric.

You'd have to adjust things a bit for just 18mm -- all the inside bits are 12mm.

and what is the deal in the US... are you guys getting Xmm material and they are just naming it Y"?

Or is there real 1/2", 5/8", & 3/4"?

Of course baltic birch is the 1st on the list of build materials.

I think its all in mm here. If you measure 5/8" MDF it ain't no 5/8".

By the way... izzat you in the photo of the alpha build?

Keep working on this thang. I'm waiting for the final verdict. I'm still busy sourcing parts for a 300b monkey, but a little speaker diversion is possible.

I believe 3/4 here is actually .700 inches which is 17.78mm.

I think that's right. It's about .05 shy so it'll glue up nice in a .750 dado.

Geez, I never really considered a single driver system until I saw this. I am looking for a lot more for my 'den' but it would be great in my son's room. Even at 6 years old I'm happy to say he would probably appreciate it. Gotta start them young ya know. Just gotta sell the Bose 501s i was gonna dust off for him to fund it.

regards.
Marc

Chris - thanks for the reply, much faster and more informative than expected.

The reason I have been pushing for the fe126's over the 127s is because I wont have more than 10w really. (SI) The 127's would probably be loud enough, but I would like as much headroom(efficiency) as possible.

As for the comparison between the Fostex recommended design and the frugels, I was just curious which you preferred, disregarding size.

I havent ruled out 127 folded (far from it), Im just hoping for a more efficient (louder!) alternative, thus my interest in the 126's. How would you (either of you) compare the frugals to the folded monopole 127 design? I realize they are very different speakers, but might as well ask anyways.

Just out of curiosity, when you coupled with the sub, was the HP filter passive? Also where did you do crossover? Sorry if I sound like Im nagging, Im just hoping for a HT system that can play music without being too fatuiging. Perhaps I hope for too much.

Thanks guys, sorry to sound like a broken record but you're awesome.

Default plywood in the States

Some places serve up "Baltic Birch" in square sheets and reference it in mm.

Most lumber yards, though, sell in English units. There's a pretty wide variability in what makes up 3/4" ply. Enough that creating a dado to fit it is best done with an adjustable jig and a pattern-following router bit, IME.
