Tweeter The M originally used a plastic dome tweeter to reproduce the high frequency spectrum. Now that we’ve used up all NOS parts, the replacement is a soft cloth dome tweeter. The price of the upgraded part is per pair.	$140 ² ⁴
Crossover The crossover is the electrical circuit that protects the tweeters from the low frequency energy that is reproduced by the main drivers. This can only fail, in rare instances, from overdriving the speakers.	$55 ³

The Ohm M was the satellite part of Ohm’s first sub-woofer/satellite system as introduced in the mid 1970s. It had a metal cabinet, 4” woofer/mid-range and 1” dome tweeter. It was vented to increase the output headroom and had a built-in high pass filter. The sound of the system with the sub-woofer matched the high end Ohms but took up a tiny fraction of the space.

Ohm allows up to $350 for the return of a complete pair of undamaged Ohm Ms toward 25% of the purchase price for new Ohm speakers.
