All the sims Scott did were in Martin's sheets, but any TL Modeler should do. The approximation is close enuff that one can just model an ML-V (ML-TQWT).

It must be a record - this thread still going after all these years. I've seen plans for the bipole FE126e(n) and wonder if anyone built those and what the feedback is. Similarly I wonder if anyone made a bipole with the FE103E(n).

Thanks, AM.

Thanks Dave,

I don't know how I missed the reply back on August... I just got E Mail notification today on the latest post, and saw your answer.

I have an ML-TQWT simulator I can use.

Hi Friends , i like Metronome project. It's look like very eays for building and it's looking very nice. I have got a pair Fostex fe167e drivers on bass reflex cabinet. I want build a metronome and i read 30 page on this topic and i will continiue to read. I find metronome plan for FE167e on Dave web site. ( http://p10hifi.net/FH/download/metro...67-1v0-map.pdf ). But i don'd find measures of the top section and port. My other question : Will i use any insulating material on the inner surface? Thanks to everyone and best regards.

yildray35,

Checking my notes from when I built an FE167e Met 8 or 9 years ago, I used:
port Dia = 3"
port L = 2"
cabinet dimensions:
internal height = 60"
Z(driver) = 30"
S(0) = 4" x 2.5"
S(L) = 10" x 7"

Cover ONLY the BACK interior surface with felt or acoustic foam; IIRC, I used foam; probably 1.5" egg-crate style foam, but I'm not sure.

I did use BSC; 0.7 mH and 1.5 R; but this will depend on your preferences and room conditions.

Cheers, Jim

Thanks my friend! Now I clarified in my head.
Cheers!
