I presume I need to resolve these questions before I start gluing my panels together as I'll need to cut a space at the back for the terminals prior to assembly. (The Fostex website gives a nice schematic of the driver so I'm happy proceeding with the front of the cabinet before the speakers arrive.)

Appreciate your thoughts.


The location of terminals was intentionally left off the design drawings to allow flexibility

I personally like to keep the internal wire routing as short as possible, and mount mine on the rear slanted panel approx 75mm from the top.
In line with the "frugal" philosophy, there are several very inexpensive types of binding post / terminal cups or blocks that can be mounted externally, I like using a 2" cup with 5 way binding posts as it recesses on enclosures' rear panels, and also allows a bit of a hand-hold.

If you're ordering drivers from major distributors (Madiosound, PartsExpress, etc) terminals wouldn't be included, but can certainly ordered separately. I wouldn't spend more than $3-4 per enclosure for terminals.

whether /how well any particular 8" driver would "theoretically work" in this design is hard to say, but it is likely that the fit would be very tight - at the very least might require another spacer between the enclosure front panel and supra-baffle

If you can fit them, maybe. and if you can make JX92s work, you are likely able to make A10.2 work. The closest -- size wise -- we have done is FE138eSR and it worked well except where it fell on its face from issues not influenced by the FH3. Used as a bass driver in a FAST with FF85wk, very good.

Try JX92 and report back.

They're only 140mmdia, so should fit in OK I think, don't think they'd go back too far...


will report back....

I mounted these terminals, which require only a small opening, 12 inches from the top. That distance still allows access to wiring after the cabs are glued up. They also look good at that location.

Thanx for the URL, i'd been looking for those on PE site (and not finding them) for some time. We use a 2" cup with the same posts (preferred over the solid metal ones)

I've used those ones too on a couple builds and they are great and inexpensive
