Fe103e Mltl

[larkinrulez]

Hi...

My Zigmahornet did play music for a couple of weeks now and I still like them.
BUT...somebody wrote, that the Ziggy is a MLTL that was constructed in a time, when nobody really knew enough about this kind of enclosure to do it perfect.
OK....the FE103E works good in a Ziggy, so an MLTL seams to be a good thing for this driver. Is there any better MLTL-design than the Zigmahornet out there?
Dont't get me wrong....I really like them, I just want to play a little bit

Here is the text description of a 103 ML-TL for FE103 that Scott just whiped up... income tax time, so i have to hold myself back from doing a drawing....

Not that different in some ways to the Zig., but a fair bit shorter. 38in x 4.25in x 3in (internal HxWxD). Vent = 1.5in diameter & length, as close to the base as possible. Zdriver 8in. Stuff 0.35lbsft from the top 10in down, or line the rear wall, top and one side wall to just below driver height, and line the base too.

The red is the Zigma, the green the new ML-TL.

hmmm....

besides the fact, that it has even less bass than the zigmas, the curve looks quite good.
I guess I will build a prototype and let it compete against my ziggy

thnx

Ok...

I had to convert the dimensions to the one and only metric system
Will be an interesting evening...perfect for the only rainy day this week!

That's deliberate. I could have gone for greater extension, but IMO the Zig. is already pushing the 103 too hard. Better to accept the inevitable, tune a little higher, and let the driver have an easier time of it. I still like the Zigmahornet though. It's a neat design. I used to have a pair & always enjoyed them.

You did the richt thing and I guess, it will sound better than the Zigma.
I will know it by next tuesday

Bump!

Any news about this interesting post?
Or was this design abandoned for a better one?
Let us know!!!

103 Tl design?

HI Martin,
Did you complete the Zig V2? How did they sound? I'm pulling apart my Fonkens that use FE 103e cones and want another project for them. (Although the sound better than a pair of SD1's from the P.E. website, i found them lacking in comparison to the sweet sound of 127e metronomes and the ok sound of a pair of TL's using HiVI b3n's from: F. Campedelli - Home Page

Any feed back on a better TL box for the 103's would be appreciated.

So the above drawing will also work with the Radio Shack 1197s i have in storage?

Looking at the fr chart i wonder if this is a better solution or making smaller boxes and adding bass support... as always, tradeoffs with every design!

Ignoring OB or ~aperiodic, for the best of both IMO is to use a BP sub with MLTL/ML-TQWT/ML-horn loaded small and/or low Xmax drivers.

Thank you. I'll take this into account and start building something now.
