Product highlights:
3-way design
1" diamond-coated aluminum dome tweeter
dual 4-1/2" composite glass-fiber midrange drivers share a dedicated acoustic suspension enclosure
quad 5-1/4" glass-fiber woofers
Force Balanced Array with front- and rear-firing woofers evenly distributes bass and reduces vibrations
dual 2-1/2" wide-flared rear-firing ports
frequency response: 30-40,000 Hz (±3 dB)
crossover points: tweeter to midrange, 1800 Hz; midrange to woofer, 170 Hz
recommended amplifier power: 20-300 watts
sensitivity: 87 dB
nominal impedance: 6 ohms
acoustically centered architecture orients the midrange and woofer arrays in rotational symmetry around the tweeter
time-aligned cabinet geometry introduces microsecond-level time delays between the drivers, ensuring that the effective acoustic center of each driver is equidistant from the listener
chamfered front baffle and flush-mounted drivers reduce edge diffraction and improve high-frequency response
extra-thick 1" (25mm) driver baffles ensure a rigid, resonance-free mounting for all drivers
optimized cabinet construction, extensive bracing, and acoustic insulation eliminate acoustic and structural resonances, ensuring an inert enclosure and an uncolored response
dual pairs of gold-plated binding posts allow bi-amp/bi-wire configurations
two sets of threaded adjustable feet: spikes for carpeted floors, and elastomer isolation feet for hard floors
removable, magnetic cloth grille
8-5/8"W x 44-1/2"H x 16-3/4"D
weight: 59.5 lbs.
