SM7UYJ,
from Billy Idol to Billy Dipole?

That fullrange driver looks suspiciously like a Fostex FP203 (or 163?). If I´m right: Could you tell more about your crossovers and your listening impressions?

Thanks

The workname for this project was "Billy the speaker!

Rudolf: -"Right you are - I'ts a Fostex FP203!

The tweeter is also a Fostex salvaged from some old speakers of unknown origin.

The crossover has just been rebuild using oil and MKP capacitors.

The woofers LP is set to 300Hz where the FP203 takes over. The tweeters help the top end from abt. 9kHz.

I'm pleased with the sound, and think they produce a verry dynamic sound and great bass.

The woofers need some compensation from 20 to 50Hz to get flat frequency response - but thats in the future plans!

Fergs! Wonderful to hear from you .... The Gippsland coast is a great place to dwell - (especially in summer) ... I'm moving myself - on Tuesday ... back home to SA - to the Barossa Valley ... could be the death of me).
I'll pm you tomorrow.
Cheers
ALF

Here is a project I'm working on, called the BaSSlines. First is what it will look like when complete, with Lexan and laminated hardwood baffle. Second is the prototype out of mdf. Just the mid is open baffle.
