The only Ohm's that have ever used a REAL "Walsh" driver have been the original Ohm A, the Ohm F and the Ohm G. Anything else that has been marketed as having a "Walsh driver" or sold as part of the "Walsh series" has nothing to do with the earlier designs other than a similarity in name tags. They are "pretending" to be heirs to the throne but do so in name only.
Here's a website that may offer a small bit of info about the earlier Ohm's and has a few pictures to check out. If you have further questions, drop me an email and i'll do what i can to help you out. I am pretty familiar with the F's as i own two pairs of them and wouldn't mind owning a pair of A's. Just keep in mind that both of these are low impedance low sensitivity designs that are very demanding on amplifiers.
The G's are higher sensitivity as they make use of a newer Walsh driver that is both smaller and lighter. Rather than being a sealed design, it made use of a passive radiator to help reinforce the bass that the smaller driver probably lacked. If i had these, i'd probably pull the passive and install a woofer, using the smaller Walsh strictly for the mids and highs. Sean
