loudspeaker systems designed
specifically for the Dance Club
Market. MD2 is a mid-high

Drive®transducers for mid-band
reproduction and the 2453H-SL
for high-frequencies, the MD2
handles frequencies from 300 Hz
to 20 kHz. The MD2 is intended
to be used in conjunction with
the MD1 super tweeter, MD3 low-
frequency system, and MD7 ultra
high-output subwoofer system.
When all elements are combined
they complete a high energy five-
way dance system with
unprecedented fidelity, clarity,
and breathtaking purity.
