These are not Ohm Walsh, but for $20 you can't go wrong. There must be some marking that indicates what model it is. If you can't find that, you can call Ohm. They are extremely helpful over the phone.
Thrift shop find, Ohm Speakers
I found a pair of speakers at a local thrift shop today. They are a 2 way pair of bookshelf speakers. I couldn't find a model number, only the name Ohm on the back. The front of the speaker also says Ohm in the upper right hand corner. I didn't have my cell phone with me so I couldn't take a picture. The store owner didn't know if they worked but they are being sold for 20.00 a pair. Is it worth me buying these to play around with? Were their 2 way speakers any good? The only Ohm speaker I remember were the F with the large Walsh driver. These look to be just a pair of 2 way speakers. The cabinets were around 24 inches high, 10 inches wide and 12 inches deep
