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

Don't be put off by that response graph.  My 2000s' response graph had a similar overall shape.  IMHO, systems that tilt downward to the right are much more listenable, realistic, and involving over the long run.  If you want, EQ the system to be flat and see how you like it.  I know I would not like it at all.

What equipment including amp are you using to produce the response graph?

Did you do one on the whole speaker prior for comparison?

Also remind me how old are the speakers and which gen driver?

The graph was a Walsh driver no tweeter, so that would be like listening with an ear infection. The driver is only four years old so pretty new I guess. But as I said before, when adding the ribbon tweeter and rear tweeter to the equation the package sounds incredible. But I know there's a diamond in the rough hidden in there
that will come out when I release the "Spaghetti Monster"...

Time for an espresso.....🇸🇪

Mapman...
The amps  are the big Emotiva mono blocks that will put out close to
1kw at 4ohm. The test software is in my iPad mini with a outboard mic.
Let me dig in to my files and see what I have saved.

Later.....🇸🇪

What is the mic?

Also are these series 2 or 3 drivers and new when acquired?

I ask because older drivers could easily not perform as well for a variety of reasons.

Also room acoustics typically provide bass boost versus measuring in something more like an anechoic chamber to whatever extent that might be a factor here.

Also I’ve seen measurements of series 2 Walsh speakers from teh 80’s and curves were reasonably flat with typical deviations. Of course that was entire speaker and no way to know how one set of test gear and conditions compare to another.

I would not listen to the Walsh speakers without the tweeter. Listening from behind with no tweeter exposure confirms that.

I would expect the bass driver to roll off as frequency goes up to some significant extent.

if original response with tweeter was reasonable flat as it should be that would indicate the tweeter and crossover together with the bass driver provides that. No surprise there.

No commercially sold Walsh or Walsh style driver I know of can cover everything and operate reliably over time. Dale Harders newer models are the most recent attempt I know of. Original OHM Fs did it to 16khz or so when working but that was very tenuous.

I would only judge the sound and performance as measured of the complete package, not the parts. In a project like yours however its of course important to know what each part is doing.

Interesting stuff.
