ALUMINUM CONE
The spun aluminum cone provides outstanding con rigidity and lowers distortion. Ad-
dtionally, the combination of strengh and weight allows for higher output levels without
cone break up.
DUAL 4-OHM COPPER VOICE COILS W/ BLACK ANODIZED FORMERS
For high efcient thermal transfer, the voice coil is constructed with a black voice coil
formed from anodized aluminum wound with 99.9% oxygen free copper. This makes
the voice coil highly efcient in dissipating heat while improving power handling capa-
bility.
DUAL LAMINATED COTTON SPIDER (DAMPER)
The spider provides a rigid progressive suspension for the woofer cone resulting in
better bass response and excursion capabilities.
HIGH STRENGTH GLASS FIBER ENHANCED SURROUND
Machine injected high strengh glass ber enhanced rubber surround for the top sus-
pension adds mechanical strength and reliability. This also provides a softer lighter
suspension increasing effciency.
