Description

In brief

A mid-high top for use above bass cabinets. The drawing gives the frequency range, crossover frequencies, coverage angles and suitable drivers.

The MT 102 is a mid/high top by Rog Mogale: two 10-inch midrange drivers work into a common flare, and above them sits a compression driver with a 2-inch exit on a horn. It is intended as a top above bass cabinets, not as a full-range box.
