Celestion TSQ2145
21-inch cast aluminium chassis neodymium magnet low frequency loudspeaker - 1800 Watt - 8Ω
Advanced temperature control using 3-channel tuned venting system provides highly efficient cooling across the frequency band. Voice coil typically operates at 30°C lower temperature than other leading drivers in this class. Polysiloxane laminated triple suspension provides much greater stability and improved cone displacement symmetry. Lead-out wires precision woven into suspension minimises excess motion and reduces fatigue. Double-sided, weatherproof cone coating enhances durability.
