Ohm I

    The Ohm I is a 4- way system with a built-in sub-woofer in each cabinet. Designed in the late 1970s (before most people had heard of sub-woofers!), it held Ohm’s record for highest output head room until the development of the Walsh F-5015 in 2013. The speaker can handle 1500 watts on most systems! In addition to the 12” sub-woofer, there is a vented 8” woofer/ mid-range that operates from 100 Hz to 1700 Hz. This driver is mounted on the top of the cabinet and has 360 degree dispersion. Also on top of the cabinet is a 1.5” low tweeter and a 1” high tweeter. On the front of the cabinet is another 1” high tweeter to extend the treble.

    The Ohm I features a bi-amplifiable design, with separate inputs for the subwoofer channel and all the rest of the drivers. This feature can be overridden by means of a toggle switch on the input plate to make all the drivers work on one amplifier. The Ohm I has no active speakers. In order to use the bi-amping feature, it is necessary to have an external electronic crossover, which exists in most home theater system receivers.

    • There are many upgrades for the Ohm Is. The 12" sub-woofer can get a SubBass Activator and vent adapter to extend the bass below 28 Hz. The 8" mid-woofer can get a new cone with a smoother transition to the low tweeter. The Low Tweeter can go to the new 2" metal dome. The front high tweeter can go to the 3/4" metal dome tweeter. The crossover can have upgrade poly-caps.

      Completely upgraded Ohm Is are sometimes available. Call 800-783-1553 for availability.

      Note: Most Ohm upgrades require no specialized knowledge and are easily completed completed by any person. It takes less time to install your own upgrade than it does to package and return ship your speakers to the factory, therefore, we recommend you save time and money by doing this yourself. We ship the upgrade to your door with clear, easy instructions. If for any reason you prefer to have the factory complete your upgrade installation, we will be happy to do this for free, however, you will be responsible for shipping and handling costs each way.

    • Ohm allows up to $1550 for the return of a pair of complete undamaged Ohm Is toward 25% of the purchase price of new Ohm speakers.

    SBA for Sub Woofer

    The SubBass Activator is an electrical circuit which extends the deepest bass when the music calls for it, reduces the distortion for cleaner sound, increases the dynamic range for greater impact, and uses a self-resetting protection circuit to reduce the chance of damaging the speakers. It comes with a Vent Adaptor which easily slides into the vent to tune the cabinet deeper to get the most out of the extended bass.
