Thanks Scott!
Yes, the part about it being more forgiving of different drivers is important.
With my voigt (no 'h'
) pipe, the detachble baffles aren't larger than the front baffle. That cabinet has taken plenty of abuse (just ask Josh) and I'm looking to make this aspect a little more elegant for the FH3.

With tongue firmly in cheek, Bob. Wasn't that what your neighbor P.W.Klipsch did lo those many years ago? Sort of.......

Hi all,
After reading posts 473 onwards, and hearing a couple of pairs of FH3's. My personal opinion is though the box may not be strictly a horn it certainly has that 'easiness' about it, in abundance.
When coupled with the Mark Audio CHP-70 the sound is lifted from something ordinary [sorry Fostex!] into another realm of audio experience.
Thats just my personal opinion though Those with a sneaky suspicion that I might be right can audition mine, see the list.
Regards - Jim

If you are going to flushmount a driver 15 ply is probably to thin. But with a FE 126 you are probably not.
If you are talking MDF on the other hand 15 mm is to thin for anything but very small enclosures.
Baltic birch ply is best and available in the EU ... I would use the 18mm (cabinets will be heavy). You can also tapper the 'inside' of the driver hole with a router for better fit and sound. Birch ply looks good when stained & polished.
excellent price - that's less than CDN wholesale jobber cost
FWIW, 15mm would be adequate for the FH3 if using FE126E (which needs less than 3 rebate ) or not rebating for flush mounting the Mark Audio/Alpairs.
If using 18mm throughout, parts, you'd likely want to modify dimensions to adjust for additional 3mm thickness per layer of internal parts. ( i.e. 9mm deeper / 6mm taller ) Sorry for the metric, try as I might I can't think in imperial when it comes to cabinet making - round to the nearest 32nd" is close enough.
All the rest of the countries of the world do. The one that manufactures everything less babies in the world saw fit to do so and here I am in Argentina using one of the measuring tapes you mention, being that we have been metric since 1886.
Don, are you sure you're a native Canuckian ? - you forgot to start or at least include "I'm sorry" in your first sentence.

We used a combo of cotton (wool) felt on surfaces near the driver to minimize reflections rhtu the cone, and well teased polyfluff (polyester wool, dacron wool, acoustistuff, pillow stuffing, BAF) to damp the line. The pointy bit as per the diagram, and some just above or below the driver to taste.
