1. Introduction
These cabinetsis designed for professional stage performance .Using density
Particle Board and high quality carpet for the body of the cabinet made it more
durable .The special handle shows unique Italy style. With the accurate
crossover point made the timbre very clean.
ES12M adopt special horn in polypropylene reinforced. With wide directional
angle 80°±10°(1KHZ-16KHZ)and 180W AES/360W Peak power. Matching the
ELVIS 12S/15S(SUB WOOFER) with ELVIS 12/15 made the acoustics of the
cabinet clean and the bass strong.All thesecharacters made it very suitable
for any place.
