Since 1975, Ohm Speakers have utilized their proprietary and patented loudspeaker technologies to produce their famous line of Walsh and Micro Walsh loudspeakers, sold factory direct.
The current lineup include the top of the line 5000, which is 13" square and 43" tall with a claimed frequency response of 47 Hz to 20 kHz. There's also the 4000, 3000, 2000, and 1000 named for the average room size they're intended for. The MicroWalsh SE, 6" square and 36" tall has a claimed frequency response of 80 Hz to 20 kHz.
All Ohm speakers have a 120 Day Home Trial program, so the customer can break-in the speakers and still have plenty of time to try them out.
