I have Ohm Walsh Super 2 S3s (what a ridiculously long name, no?). This is the old, discontinued Walsh 2 cabinet with current Walsh 100 S3 drivers, similar the ones you are asking about. I haven't heard the old MKII drivers, but I can tell you that I'm thrilled with these speakers so far. If you do go for it, I'd ask about the Super 2. Ohm cut around $400 off the cost of a regular Walsh 100 pair, and according to them, they sound identical (just look different).
Anyone Hear New Ohm Walsh MKIII driver upgrades?
I have the Ohm Walsh 200 MkII and am wondering about the "NEW" MkIII with the new silk-dome tweeeters? How do they compare? What changes were made? And most importantly how do they sound? .....And has anyone sold their Walshes and been satisfied with another speaker manufacturer?
