Ohm Walsh Micro Talls: who's actually heard 'em?

Back in the saddle....

Didn't really jump out of the saddle, but needed some breathing room and some away time from Audiogon.
I did take some time to re-asses life IE. I watch a crap load of YouTube videos, a few trips to the fridge, and a lot of napping.
And I also realized that I can have a triple espresso and take a nap
no problem...

So what about the Ohm's? Come on people you didn't think I would
give up after all that work...Did you?

Between the naps, the snacking  and coffee breaks I been very busy
working on the speakers. I finally got to the point were it's looking
nice inside the cabinet. Yes all the horizontal layers are done, and I 
used a large sheet of CF on the inside to stiffen up the mid line of the the cabinet. To add even more stiffness, two horizontal bolts were pre-tensioned between the CF sheets and locked in with epoxy. 
At some point I realized that if I had no idea what specs the Walsh driver has, I would be up shits creek and all that work would be for nothing. So what to do?
As luck has it I was doing some Googling on the internets one night
and Voila'.....
I found the driver and with that all the specs, lucky me!!

The next step will be to build a vent tube, yes, yes, I now I could
just re-use the original 13" tube that came with the speaker, but what fun would that be? So I'm stepping it up and I will try something different, and it won't be round. 
I might also add 3/4" MDF on the outside of the cabinet for even better sound deadening (unless the whole thing weighs to much).

More coming very soon.....🇸🇪

Looks good Peter!
I can't wait to see it in person.

Heavy speakers....

So the weight is adding adding up fast, and then I decide to make them heavier...!!

So after a few days of pondering design, shapes and other life altering decisions 
MDF krept in to my conscience again. MDF is great stuff, easy to cut usually flat and easy to finish....but dusty lol.

So I decided to change the shape a little, I want to add a taper at each corner (as you can see in the image) the outline is the blue tape 
as a visual. I will add two layers of 3/4" MDF so the bevel/taper will be a little bit more aggressive than in the image.

I think by giving the cabinet a few more angles, the design will perhaps  be more modern and hip looking.

As I said, it's getting heavy........🇸🇪

Shapes, shapes...??

Another day and another thought.....

So as you can se I did some "Thinking" and the shape has changed
as fast and as many times as I've taken showers.
So today I decided that the faceted design is the bees knees. I got MDF in my shop, plenty of glue and drywall screws. The shape will be very "Jewely" chiseled and more shapely.

I do like the truncated pyramid look, but it's getting a little old, so changing the shape could be exciting.

As you can see I roughed  out the top with some square wood pegs just so I can have a visual, not necessary a final look but close enough. I will go with a new ribbon tweeter I found, check it out...

The woofer port is another "many shower" issue. I have played around with the idea of keeping the tube I would just compensate for the interior volume. Rectangular port, and finally a passive radiator (PR) on each side of the cabinet.....
I might take the leap going with a dual PR set up (2x12") well see
and I need to decide which direction I'm going before I start to cut my MDF tomorrow. The cool thing with the PR is that you can tune the port by changing the weight of the cone and spider.
The other positive is that I will have less height of the cabinet as I don't have to worry about the bottom port...

That's it for now......🇸🇪
