Is anyone thinking about building Walsh drivers?

FWIW their was a DIY room at the last audio show I went to (no Walsh speakers unfortunately) and I came away thinking how silly the DIYers sound made many very expensive offerings there seem. I'm surprised but happy they were allowed there. The DIY stuff hit way above what one might expect but was certainly not pretty. Lots of pretty impressive looking gear as a whole there though.

The thing I like about Audiogon is that it sets a high standard for home music and sound quality. Where it becomes interesting then is all the different recipes out there for good sound at all price points.

Fraz, the one significant enhancement with my OHMs recently was placing the 100s in my family room on Aurelax Subdude platforms to minimize interaction with the suspended plywood wood floors under the carpet there. That totally transformed the sound in that room by getting bass interactions with the floor under control. Inexpensive and definitely worth a try when called for.

My big F5s sit on solid concrete foundation. The 100s upstairs now sound more like those I have set up fairly optimally downstairs.

Interesting Map, that is one thing I really didn't mess much with was base platforms when I had my Ohms, just goes to show you, one never knows what affects these seemingly simple things will have.

With my Larsen Model 4's, I do have them sitting atop Base isolation platforms from the UK, and then a set of four SD footers between the Base platform and bottom of the speaker cabinets. Seems to work a treat. I am on a slab with laminate wood flooring, which can be an interesting thing to deal with at times, depending on speaker. My Obelisks seem more screwed up n the bass end on this floor. Something I still haven't totally worked out but getting there!

Map, that's the 'problem', IM not so HO...the Walsh concept/approach is almost in stasis, except for the German Physiks units. Although I've not been fortunate to hear any of them, the methodology appeals to me...

(I try not to 'rant & rave', but you'll pardon me if I edge into that territory...*shrug*)

I've decided what & where I want to take my 'little project', in my odd sort of fashion.

A 3 way Walsh 'stack' has a certain 'bent appeal' to me. I realize that this might offend the 'full range F' folks (sorry, Map *G*), but it just might have 'legs'.

Start with a carbon fiber 'woofer' at the bottom.
The 'mid' (in the middle, natch) with an aluminum cone, lighter than what I'm currently using (2 mil vs. 5).
The 'tweet' up top with titanium foil.
All drivers selected for high heat resistance and capable of handling serious wattage. No more voice coil frying, no. And, loud is fun now and again...
(No wrinkles in the bass cone, either.)
The surrounds of a sorbotane/EVA laminate. The sorb on top with the EVA (which in my experience is stiffer and can hold the other up) underneath in plane.
I'll stay with the PVC for structure. Strong and has its' own absorption characteristics. Sheet stock available in black, but it likes paint for the tube stock.
I want to try to avoid 'mystery materials' on the cone interiors as much as possible, as it seems to me to be problematic in the long run. But I'll be happy to be proven wrong if that's what goes down.
Active EQ, obviously.

You heard it here, first. *G*

Lets' see how many iterations/'v.X' I get to slog through... ;)

...but I also intend to continue making the smaller (6") units better as well. I like the size of the 2 pairs I've currently got running, and they'd benefit from better drivers/cones/surrounds. That, and a tweet on top. Set up with a sub and they're pretty sweet now (if I ignore some obvious resonance issues for the time being), and the breed could only improve....

Besides...when you run 2 pairs of them in a surround fashion, even with just L&R channels (as I'm doing), 'interesting' things happen acoustically. Things 'localize' themselves 'where' on might not normally expect...and stay put...

Cheap thrills *L* perhaps, but it amuses me enough to continue pursuing that effect as a 'side experiment'. I've touched on that subject elsewhere as to what I've got in mind with that....
