glad I missed the postal strike
The bad news is that they haven't sorted this. The good news is that they are starting with 24 hr localized srikes. Given strides in service improvement, every postie could strike one day a week and we'd still have better servce than 5 years ago.

I was on the midnight shift getting as many paks ready for the mail this AM as i could.

Here is a photo of the contents of one of the packs done last night with captioning.

To accompany the flat-paks i updated the damping diagram (added some detail) and a full-size template for the side cotton felt.

Just a side note. In past cabinets I've done... one of the best cheap materials for cabinet linings is two or more layers of 100% wool army surplus blankets. Wash them and throw them in the dryer to felt them up to a higher density. But directly behind the driver you cannot beat Deflex for dampening reflections as most of you prob know. It's just amazing stuff.

If you get a flat-pak that has the thick grey foam in it, keep the foam. This is the same stuff i use for damping in aperiodic vents.

Default FH3 supra baffle

Question about a pseudo front-horn....

Once many moons ago just out of curiosity I bought a a pair of bamboo salad bowls from Target that had a contour that looked suspiciously like a horn profile (hey they were only 20 bucks). The base of which was almost exactly the same size as the cone diameter of the FE206. So I cut it out and blue-tacked it to the front of the driver in a Decware HDT cabinet. I don't think it was much of a horn effect because the bowls were only about 10" deep and maybe 15" in diameter if I remember. Not that it's important but I think the HDT is a transmission line. What I noticed was a slight raising of efficiency (a little louder) and a touch more lushness or presence (not sure how to describe it) in the midrange and without any detectable negative effects that I could hear. I liked it and thought it was an improvement.

What do you guys make of this? It must have something to do with a combination of pseudo-horn loading and baffle effect, no?

Could this type of thing be added to the FH3 to good effect?... assuming the proper size and contour "bowl" could be found, or made.

If anyone cares, here is the thread where I was discussing them... Decware DFR8 forum post #36

Post #39 May'06...

It sounds great! A little more efficient, more midrange detail (as if there wasn't enough already!) while still sounding smooth and not bright, midrange is more "juicy" for lack of a better word, and a hair better bass. Only downside I can see so far is you lose allot when not seated unless you're clear accross the room. Putting something under the fronts to tilt them back could help that.

While these are not large enough for a "true front bass horn" I think they are helping the mids by compensating for some baffle step loss.
