selling 2 Ohm I speakers in very good shape / working condition
they are pick up in Burlington only
reason for selling downsizing to smaller speakers
price is $1200

here are some details:

he 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. However, since many such systems only allow a single output for the subwoofer channel, and a pair of Ohm I’s requires two, Ohm makes subwoofer amplifiers available for purchase for a pair of Ohm I’s that split the signal from a single subwoofer output into two, in order to plug into both speakers.
