I like the look, funnily enough I'm trying to achieve the same only opposite, black sides veneered front. Nice to see it in the flash so to speak.

Lovely work. I like the contrast from pale to dark.

As I suspected, gluing the final side tight and substituting the 4 ohm series resistor made a nice difference. I hooked up the Needles in their place today the difference was huge. Even my wife, who was a bit nervous about the increased size, came into the room and asked how long it would be before the "nice sounding" speakers would be back. The Needles were just too small for our space.

wow really awesome bobtrancho!
Emmm... sorry for my newbiness but what's the wool felt carpet?
Is something totally different from the acousta-stuff? or polyfill - polyester wool?
And where exactly did you added the cork?

It's just woolen carpet underlay. Should be cheap and easy to get hold of from your local carpet peddler, so it's actually easier for many people to get hold of than Acousta-stuff or hollow-fibre stuffing. In the UK for example, both of the latter can be a pain to find locally, while you're tripping over carpet-sellers in most cities, and if you beg nicely, they'll often even let you raid off-cuts, or skip.

Underground, overground, wombling free...

A womble. Orinoco to be precise. Wombles are a curious species. In the UK, they live in burrows under Wimbledon Common, though are to be found all over the world, and generally recycle rubbish, unwanted items of all kinds etc.

My local home center sells the wool (it's not really wool - some synthetic for sure) underlay for $2.50 a yard. I used less than 2 yards in these.

The cork is simple roll cork sold for making your own cork board or for gluing to a wall. It's 1/8" thick. It just didn't do the trick in taming the FE206's highs, though, so the wool felt went on top. The cork also costs 3x as much as the underlay.

I got the edging on today and now that I'm looking at the almost finished product I think that I'll try to keep the FE206 cones as close to natural as possible. With black phase plugs they complement the cabinets quite nicely. They'll pass WAF I'm sure.

Martin King and Jim Shearer are coming by a week from tomorrow to give them a listen. Martin is bringing is portable BSCs and Jim has kindly volunteered to bring his Metronomes! I might as well extend the invitation to anyone who lives in this general part of the world. If you are within driving distance of Saratoga Springs, New York and would like to come, just drop me an email and I'll send along directions.

Sounds like an interesting session. I forsee, in my best Nostrodamus fashion, the following results:

1) The 206s with or without BSC will blow both Needle & Metronome out of the room WRT bass power & SPLs.

2) The BSC circuit, which I suspect in this guise will also serve useful duty as a shelving filter, will tame the highs. You might loose a shade of detail due to the reduced efficiency with a low power amp, an SS amp of reasonable power won't care tuppence.

3) The Metronome will cream the 206 (which itself is no slouch) in imaging & midrange / treble detail.

4) A good time will be had by all.

<rant> the transliteration for the Greek ∑ is S not Z*</rant>

The 206eSR may just needs a series resister to work in Chang, Curvy Chang or Half Chang. Chili Chang is designed (for FE167, just awaiting curved front from Ron. FE168e∑ (& 166) may work with series R.

Another driver not yet addressed is the FE126e.
