Ohm Walsh speakers

Happened to see their new line of speakers at their
website and if the new ones sound as good as the last
pair I heard, they should still be a good value.
Speaking as an ex-Ohm F owner, historically the Walsh
technology has been greviously flawed.
The composite metal cone of the Ohm A & F rang like a bell.
The so-called termination at the bottom of the cone was more
of a reflector than a terminator. The cone was very heavy
which made the speaker very inefficient. However, the voice
coil had to perform as the voice coil of a tweeter. That
meant that dynamic range was very limited and voice coil
burnout was a constant threat. In order to make the voice
coil light, they had to sacrifice Xmax, big time. As soon as
you drove them in the bass range, there was a ton of
intermodulation.
The second generation Ohm speakers were a travesty because
they sacrificed most of the unique potential benefits of the
the first generation speakers in order to address some of
the problems I listed above.
There were or are some German Walsh driver speakers, but
from what I could see they shared a lot of problems with the
first generation Walshes, described above.
