SimonRA, Have you tried the boxes with the tweeters on the inside?

Not until 10 minutes ago when i read your post... just swapped them over to see the difference but it's difficult to discern without being able to quickly flip between the two set-ups. What difference should I hear?

Will this TL work with the classic ceramic magnet 25f-ew? The tweeters of a26 kit seems to be expensive compared to 27tdfc I wonder if I can use the 27tdfc in tl design as well with the 5uf filter cap.

Why not present a 21st century offset driver option for this driver?

Default Morel UW1058

simonra
if you like use the not cheap (Neodym) Morel UW in a seeled 48-50liter
volume- very stable cabinet.
In same volume it will work too as a vented cabinet and plays a bit deeper.
The main reason for me to use closed is that it has less complication with
room frequency modulation and a bit juicy punch.
As Active Modul i use a IMG Stage Line D300 to drive that little Monster.
You can also test the Morel ore other bigger Speakers 15" 18"- Eminence
without a cabinet- the bass is room coupled and can play a bit lower its own
resonance, only my own tests and some experiments.

What cap will be suitable for 25f-ew and 27tdfc tweeter combo in a A25 style aperiodic cabinet? These drivers were recommended replacements for the old Alnico versions in a Dynaco A25 which had a 5uf cap (and bunch of series resistors).

Click the image to open in full size.

The string of Rs should alter the XO point as well as the level.

All A26 driver parts on hand. Brought home some decent 5x5' BB ply from MacBeath today. Hopefully making sawdust soon.
