Al, if you need felt for critical locations, LMK the sizes and I should be able hook you up. I'll email you the details of this stuff.

Brian, I actully spent $1.50 at JoAnn for the felt, so I'm good there... and, busted on the inductors, since it was from my local surplus guy. Recommendations on GOOD inductors, since I didn't see any on eBay... this is just an area out of my league.

So, felt and poly-fil, felt without poly-fil, poly-fil without felt?

I believe the felt is a good idea. I've built speakers before with mostly poly-fil and this time I used only felt and I thought the only felt was much better at controlling reflections off the back wall of the cabinet.

It is essentially a BR. You line the walls of a BR you do not volume fill it.

With about 20 hours on them, the imaginig is pretty good (placement is critical), but they are still just a bit 'honky' on hard rock, really sweet on Alison Krause, and all over the mid range (guitar, piano, banjo, vocals). Mayhaps a bit tinny on top. Some of this may be the tube amp, or the cheap DVD source (may have to try this with the Ayon CD-1), but I'm pretty sure the speakers need some adjustment.

Afraid the felt is insufficient - can some Poly-fil help? Will the filter help? Really close, but tweaking is what DIY is all about.

Hard rock and 2" drivers are a challenge, I have not found them large enough for this kind of music. The top end has been good in my case, based on use of SET with Magnum Dynalab FM tuner and a good channel. Have had good results with Dual turntable although cartridge was a bit too rolled-off on the top end compared with the tuner for my taste. Have had mixed results with CD player, seems the usual problem that most recordings are poor unless I am very selective.

The Twin pair in my uFonken^2 don't do so bad.
