Needing help matching 10" woofer in Ohm FRS 15 , I have set of Ohm FRS 15 with one woofer went bad . The size of the woofer 10 inch . I probably have to change both woofers to be a match . The deisgn uses 10 woofer and one paper cone tweeter only . I'm hoping to get input in this matter to help me getting as close as i can to the orginal sound .

Larger Ohm Walsh woofers(really a full-range) are harder to imitate than the smaller ones.
It will be much easier to have it repaired, and a matching surround put on the other as a prventive measure.
Otherwise, get a mic, learn to measure, and figure out the behavior of the good one. Then you can hopefully find something similar in behavior.

Only the Ohm Model A, Model F and Model G actually have Walsh drivers. The rest of the model,s even the so-called "Walsh series", are two-ways using conventional drivers with bent pieces of cardboard to act as deflectors to spread out the sound. They're no more difficult to repair than any other speaker.
Thank you it seems like solid advice . I was just hoping to run into someone who went through the same issue and found good match .
The requirement is smooth, equalisable output from the convex side, 90 to 120 degrees off the front axis. There was a Pioneer 10" that was discontinued 12-15 years ago that worked fairly well.
Frontal output is not a consistent indicator of rearward response.
The tweeter is the easy part, being used 8khz up(and from the front side)

Thank you this is plenty information to give me some guidance to go by . Speaker drivers are sooo uniqe in there spound signture that is why i seeked help .
At first i thought to get two of my Boston Acoustics A100 to donate there 10" woofers becuse i think that Boston Acoustics has the caracter ( smooth, equalisable ) but I found out that i sold that set long ago .
I tried to make this clear-you cannot predict the back-side behavior by the frontal characteristics.
Smooth response under normal front-side usage is no indicator of the sound you will get upside-down and sideways.

Ohm stopped offering repair services on their Legacy models recently for unknown reasons. It's marked as "Unavailable": https://ohmspeaker.com/legacy-products/frs-15/
Automated repair ordering does not work well, unless the one ordering is a tech familiar with the product.
Call them, describe what's wrong with the driver, they will have some advice. Good people, never a waste of time to talk with them.

I did call them and they were nice and frindly . The answer i got that they will have to replace both drivers with substitute woofers since they don't have the orginals ones no more at cost of $350 each plus shipping both ways also there might be other costs involved depending if they will find more things to be fixed ,It sounds to me that the bill will be around $1000 which i don't want to do if i can help it .
