Zaph's L18 with Tweeter in axis

check · 20th February 2007, 01:13 PM

Hello,
I heard, there was a crossover construction for http://www.zaphaudio.com/audio-speaker17.html]Seas L18 + 27TBFC/G[/url], but with tweeter in axis and backswept front wall for fase compensation. I have trouble with finding this project, especially in foreign language (sorry for torturing English). Maybe you could help me...

I think this is the one he's referencing.

This is just one of the many ways this project has been done over the years. It's the only "incorrect build" that I ever offered to fix however, simply because the guy did such a good job on the cabinets.

I don't wanna change anything
I heard rumour, that Zaph himself made a crossover mutation for project with tweeter in axis and backswept front wall for fase compensation and I can't find it...
I can't have tweeter off axis, don't always have the best listening position
DD8-MkII would be best, but it's for the older woofer and there is no redesign

Hi,

The Zaph mutation :

Reverse tweeter phase and omit L7. Revised R9/R10 values.

Trouble is nowhere does it state the revised resistor values.
they are in the broken links I presume.

Thanks a lot
finally I will build strictly your design, but with reduced BSC:
ZAPH L18, BSC issues.
