Studio Grand

The Studio Grand is a Studio Ribbon Array, (less the bottom crossover box section) mated with a matched subwoofer. For shipping the two sections were boxed separately, the Ribbon Array was then fixed by bolts to the subwoofer. The subwoofers grille covers the front bolt points.

The system was supplied with a specific dedicated active crossover (DAX) to split the signals for the subwoofer and Ribbon Array.

Connections are made via the back of the subwoofer, these are; subwoofer, ribbon bass panel and midrange/tweeter ribbon. You would therefore need 3 pairs of speakers cables to wire up a pair of Studio Grands.

Also because the subwoofer and Ribbon Array have to be powered individually, you would need 4 channels of amplification; hence 2 stereo amps, 4 monoblocks, or a stereo amp and 2 monoblocks.

These were never officially imported into the UK, but is is possible they were personally imported, if there are any UK owners please get in touch with me as I would like the chance to hear a pair.
