Our engineers have spent the past twelve months talking and listening to musicians like yourself. The results have been some of the most sensational products we have ever offered for your use. Like our Orion (o-rye-on) solid state amp that develops 175W r.m.s. Or our series 1000 amps with new dimension in size and sound. Or our exclusive JBL D15S speaker that's so efficient it's like adding more power.
