Tweeter Dome Material:
.75 Inch Composite Dome
Very smooth musical response. high output with minimal required amplifier power.
Speaker Surround:
Butyl Rubber remains musical in all weather and does not stiffen in the cold.
Cone Material:
6.5 inch Composite Poly Midrange
Water resistant composite polypropylene cone with temperature stable UV Butyl rubber surround mounted on a lightweight composite frame.
Surround/Cone Coupling:
UV Butyl
Butyl Rubber remains musical in all weather. Does not stiffen in cold.
Voice Coil:
High temperature voice coil.
Voice Coil Former:
High Temperature Voice Coil and Former
Voice coil is high temperature copper. wound on an aluminum former which allows the voice coil to handle more power while remaining light in weight.
Spider:
Woven fiber composite spider to stabilize the cone and voice coil in all musical situations.
Cooling System:
Front and rear venting allows air passage through the spider and back plate to exchange air over the voice coil.
Crossover:
6dB high-pass
