Default Pics of 3-inch Fostex in big Traxtrix horn


Just finished wiring up the baby 3-inch Fostex FE83E's in a quickly prepared traxtrix horn from some Carfrae parts I had. (See the pencil outline of the internal horn path on the side of the cabinet.)

Cable is braided multi-strand copper....wired directly to the amp.

Wow...what a sound! Not big....but very intimate and revealing.

The speakers really vanish, and despite the cabinets only being 2m apart, the sound stage is excellent.

I applied some dampening behind the drivers, plus I placed a couple of rolled up towels inside the mid section of the horn to minimise HF's.

This is just a fun project to work out if the concept would work. It does.

I'll play around with a baby sub....perhaps a small folded tapped horn.

I'll now work on a design for the overal cabinet, plus a stand. I'll also try the 4-inch unit, to improve SPL's. I think this cabinet concept would be great for the 6.5-inch unit. Would love to try a Feastrex!!

Appreciate feedback and ideas.

For sim purposes (which I haven't done) see below.


Horn length 2.5m
Throat 35mm x 95mm
Mouth 780mm x 95mm

Greetings. I would love to see this horn! The link does not work (I even registered and it still won't let me see it because it seems to be the "upload" URL). Could you re-post? Thanks in advance.

BTW RJB, I haven't forgotten you, I'm just that far behind in answering most PMs, so let me know if you get/got your Qs answered elsewhere or get into a design time 'crunch'.

Hi GM, thank you for posting the links. That is one very cool and funky-looking BLH.

Thank you also for keeping me in mind. I did finish that build (it wasn't too bad) but because I am such a poor builder, I am doing strictly OB now. I thank you for your continued assistance (and steadfast patience) and I hope at some point I can actually be worthy of it (!!!) I will post my OB results this summer, although what I'm doing is not noteworthy per se.
