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

Map,

I'm using subs - so it's hard for me to say much about the low end. John S told me that the 100s don't fall below 4.8 ohms, so a tube amp might work well. However, quick impressions reveal that the tonal balance of the speaker shifts noticeably with my Prima Lunas (4 ohm taps). I'm going to try the 8 ohm taps next to see what happens. Stay tuned..

PS If I get the energy, I'll rewire for full range operation with my ARC VT-130SE amp. The ARC is balanced in only, so rewiring is a pain in the ass, so that's a fairly big "if".

That is what I would expect with most tube amps given the variable impedance of the Ohms at various frequencies as I understand it.

The CLass D Bel Canto amps would do very well in terms of maintaining proper tonal balance in the low end I believe.

My belief is that somewhat higher damping factors (>10 say) also benefit and I did look for that also when choosing an amp.

Looks like all ohms have a thick metallic grill around the driver, does it not hinder the sound?

Deadlyvj,

It's not a thick metallic grille, but more of a thin wire mesh material with what looks like some sort of foam liner. And it's supposed to be acoustically transparent.

I actually removed the grill/can on one of my Ohm speakers to find out if it was interfering with it's sound and could not detect any difference.
