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

Holes will be drilled......

Before I continue with my writing I like to make sure that everyone understands
Im doing this for fun and my written word is just that. No implied or down playing of 
anyone else's speakers, sounds or what ever else I'm covering or uncovering when
re-building these speakers. Everyone hears differently and everyone perceives quality of
sound and workmanship in different ways......😄❤️

After that love fest....💥

Its amazing what what music masks while playing a wonderfull piece of composition
might it be classical or pop and everything in between. I'm actually having Amazon Alexa
playing me some great classical while typing these words.

Now pink noise...really changes everything, certain issues gets uncovered, a small change
uncovers strengths or downfalls in the driver. So I de-coupled the tweeter from the unit
I.E. I played the Ohm driver by it self with no help from the tweeter, and first I listened 
without touching the switches (set at my normal positions) sounds OK I guess, not much
high frequency energy but a surprising amount never the less.

I move the room size switch: Almost no changes I might hear a less then a db change
in all 3 positions.

Room location:  Free position has a small boost which is to be expected. The room size switch "small" position bumps high frequency by a small amount

Perspective switch: from close to far I'm getting almost 3.5 db difference in output
I would say that's a fairly substantial difference.

Now to the frequency output of the Ohm driver. Looking at the trace I'm not seeing 
a whole lot of output as it starts to roll of fairly fast after 2.25khz, this measurement 
was taken with the perspective switch in highest output (close) setting. Now I do believe there's a perceived output to about 4.5k but it's about 20db down or worse.

As for the crossover for the Tweeter my guess is as good as yours my friends
as I have not taken the time to by pass the big driver due to the crossover architecture.
Im sure it's crossed over at 2.5k or somewhere in that neighborhood.

Good news, bad news? I think it's mostly good, as I have a great platform to work from.
I love the concept but I think JS has left a lot of possibilities on the table, the crossover 
is coplicated beyond what I've ever seen.
What am I expecting from these changes? That's in the next installment.

Now I'm going to drill some holes...🇸🇪

Today is cork day....

Such  lovely material, warm, soft and useful in so many ways.
I do love a good bottle of wine so popping a fake cork cork is 
a let down, but I understand the Eco part of the equation.

Today I'm using real cork, 1/4" thickness with self adhesive backing
OR NOT....just opened the package from Amazon and so much for self adhesive convenience...damn!  Life's a struggle and then you decide to take apart some Ohm speakers and BAM....Moving the lawn looks like a simple project lol

I guess I have to either raid the garage for some appropriate glue or
silicone or Home Depot is my next stop..

Stay thirsty my friends...🇸🇪

I stuck my head in the box....

I love walking the isles of Home Depot I don’t know if it’s the smell or the over abundance of stuff, man stuff (sorry girls) that has to be purchased, used once put in a drawer until you need one again, but due to onset of early tool dementia you buy another one...now you have two.

So no glue in the cabinet of the ever growing collection of spray paints. It would have been way easier to have a self adhesive cork sheet as spraying glue is one messy proposition.
The Ohm 4/5k looks big from the outside, but is nothing but on the inside, Donny small hands would’ve be way more successful in all the tiny crevices and spraying contact cement is no fun.
Got it all done and here’s an images of the Cork and some polysheets attached to the braces.

Finally got a chance to stick my head in a finished box and in a factory non treated cabinet.......Wow
Wish you could hear the difference I’m expecting tighter bass faster response on transients, but the proof is in the pudding.
Im also changing up on the Tweeter (front and rear) so if some one wants 2 ribbon drivers or 2 soft dome tweeter let me know, price will be very fair.

Dinner is next with some adult beverages, till next time...🇸🇪

The up's and downs of......

So finally a beautiful California day with sun and blue skies.

After feeling that I have more great ideas then time to execute, its back to the project. I finally got the cabinets done, with a few small additions that I'll do before final assembly. Last night I pulled out the drivers, removed the last of the cage around the X-over and Walsh driver......

The downer?  Seriously what we're they thinking when they slapped together this spaghetti monster of a X-over. Do anyone remember speaker switchers of yore? Nothing good has ever been written or said about these devices, except for a few naysayers with no hearing. The image attached will say it all and it has to be removed asap.
Im still contemplating the X-over design or I might contemplate an electronic version
with infinite possible variations of settings.

I realize that 4/5000 cabinets are a hybrid old/new design, but after a little staring at the parts ( I do a lot of that lol) I suddenly saw a glaring screw-up, the Walsh driver was covered 
by part of the original cabinet....This is pure laziness and should never happen on a $5000
speaker. As can be seen in the image it's not a small area either. There is also some old
rubber gaskets left from the old set-up!!!

This will get done sooner than later, until then......🇸🇪
