Celestion TSQ1545 15" Neodymium Subwoofer Driver CN1545MD T6431B
15-inch cast aluminum chassis neodymium magnet low frequency loudspeaker
Advanced temperature control using 3-channel tuned venting system provides highly efficient cooling across the frequency band
Voice coil typically operates at up to 80°C lower temperature than other leading drivers in this class
Polysiloxane laminated double suspension provides much greater stability and improved cone displacement symmetry
Lead-out wires precision woven into suspension minimizes excess motion and reduces fatigue
Weather resistant cone coating enhances durability
