Ohm Walsh F Hope of Resurrection

Doug, If you are referring to the 4 switch control on the grill, this is only on the 5000 series and the 4900 (1 switch control) speakers. The 4000 series speakers and smaller do not have this. Presuming you have a decent sized room, you can get 4000 or 3000 series with their upgrade program. Just send in the F magnet assemblies / cabinets and pay the amount cited on their legacy page - slightly less than $3k for the 4000 series and slightly more than $2k for the 3000 series. If you want to consider this, contact John or Evan at Ohm and tell him your room size. He can recommend which speaker would work best for your situation. I also thought that they could sell you a current technology replacement driver that sits on top of your existing cabinet. Not seeing that option documented on their website now unless I have incorrectly interpreted the cited offers/costs above as being for completely new speakers and they are really for drivers for your existing cabinets.

I was in a similar situation but I have a big room and I was encouraged by John to go the F-5015 route.  Here is how it played out for me.  John and Evan of Ohm and I started discussing changing a pair of Ohm F's that I had into some F-5015s starting in 2018.  I ended up deciding to trade in my F's, received the standard 25% off of the list price, and I ordered new F-5015s with one inch thick birch plywood cabinets.  I also had the option of sending in my F's and having them changed into F-5015s at a lower cost point where my cabinets would be rebuilt and re-veneered.  They actually encouraged me to do this and said the sound would be the same except at very high levels, but in the end, I decided to spend more for completely new.  I recall that it cost around $250 to buy all the packing material and to pay UPS to send in the two cabinets and the driver magnets to Ohm in Brooklyn from Michigan.  My traded in cabinets were in very good shape with the only damage being that the lower corners were very slightly rounded due to contact with objects.  There was no damage to the particle board under the veneer in these locations.  These were acceptable to Ohm for the trade-in.  Never asked what they did with my traded in cabinets.
