Default Ohm Walsh speakers

wrote in message
.net

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.
