Hi Pete,

That last suggestion is definitely worth trying; I'll give it a go this weekend.

Thanks.

3 to 6 mH is in the ball park.
Note that this design uses 10 mH with about a 9 ohm woofer:
Could a kind soul please break down this horrid Xover

Do you have some different inductors to try?

I don't see how you could do that with the Stereophile measurements, though (averaged sum measurements).
Didn't understand a word of that really. Let's hope Christian Ponder gets simpler instructions from Leslie Frazier next year, because we surely have common ground in loving the VIKINGS. Skal!

My approach was a lot simpler. I outline it below in a visual form. 6" bass plus 1" tweeter is fairly standard stuff that works. The phase is not going to be a million miles away, though I'd dump the metal dome.

I really like PB2's suggestion of converting it to a 2.5 Way speaker. I'd guess you want to get near closed box on the Epos (Using a foam plug on the reflex) and add a 6" woofer and Zobel on a near 10mH coil, as with the B&W Matrix 3. You should then get some bass and spare the Epos from bass excursion. Wasn't there a Rogers subwoofer for the small but beautifully formed BBC LS3/5A along these lines?
