Offered for your consideration is a vintage Ohm high frequency adjustment knob removed from my Ohm Model D speakers, USA-manufactured in 1972. I believe this was the same attenuator knob style found on the Model E and possibly other period Ohm speakers.  The buyer is responsible for accurately assessing its suitability for any speakers other than the Ohm Model D and E.

So, please have a look at my large photos, the measurements I’ve taken, and read the remaining description to decide if this hard-to-find attenuator knob is correct for your speaker.

*Although the listing is written largely in singular to avoid any confusion, two (2) identical Ohm Model D attenuator knobs are available at time of this writing. Please choose if you’d like to buy one or two in the quantity field at the top of the listing. The shipping cost will stay the same if you buy one or both.



This Ohm high frequency adjustment knob is in clean, excellent condition. It’s made of hard plastic with striated grip surface and measures 1 13/16” in diameter (at flared bottom) x ¾” tall. There are no cracks, chips, or scratches. Overall, this attenuator knob is exceptionally well-preserved.

As pictured and described, this superb Ohm Model D attenuator knob is offered at a competitive price.
