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.

We are a schizophrenic country. Millwork in metric, (most) houseplans in Imperial!

This one does. But then, we would, as the heart of the Empire.

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.

15mm BB is fine. It is just fine for FE126 even with rebate. It is the Alpair7, with its thick bezel that benefits from 18mm baffles.

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.
