How does the tweeter sound, samadhi? Like a soft dome? I couldn't help noticing that keeping all the drivers paper seems to produce a nice synergy on some of the resonances. Interesting.
Its sounds better than a soft dome to me in the lower treble frequencies, and the sound is cohesive, easy to blend with the woofer without much tweaking of the crossover. Though the upper end is less detailed and fairly directional. A tiny neo tweeter on top might make for an unusal but nice sounding little 3-way.

Well, I've got some good news on crossovers, samadhi. The FRS5X8 is slightly superior on directivity due to it's little hard dome at the centre, but actually doesn't sim as well on the simple series crossover here, though it works without component changes. And series is what WLM must be using on the Stella since nothing else works as well!

Here it is for mounting against a wall. No standmounters from me! But I suspect it'll be VERY GOOD!

FWIW, I found the bigger La Scala worked very well with an AR-SXO crossover. A mere 3 components including the resistor across the bass. But then the W200S is a different animal from the trickier W130S with its horrible 1400Hz peak, which kinda gets cancelled out her in phaseyness.

This is great!
Did you BTW ever finish the "Scala" version you were contemplating, Steve?

If, as I suspect, you mean that it is wide up to a higher frequency then I might throw my 2c in to the other ring. A narrowing dispersion will help with clarity, with the tradeoff being a narrow sweet spot. To me this is the benefit of using a cone tweeter.

The tweeter has a fast rolloff below 1.4khz and 4th order acoustic slope can be achieved with just a capacitor. The W130S sounds very smooth and has good bass response for such a small woofer.

Some measurements to come shortly.

Good approach for a good sounded loudspeaker and cheap to build loudspeaker at the same time.
Here a small listening report in German from a similar version:

I don't understand this term:

Mean you the genuine device or the clone ?

In this case this threads could be of interest:

Does anyone know of a good paper tweeter?

Having modelled the WLM clones in Boxsim, I can add that the Visaton 4" W100S and 6" W170S bass drivers are far easier than the W130S and W200S.

They don't have the peaks in frequency response that the WLM choices give when you filter them. A simple 2nd order bass, third order treble and padding for level on the TW70 just works nicely.

That's where I would go on a smallish speaker in this style.
