Celestion TSQ1845 18" aluminium chassis neodymium magnet low frequency Speaker
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 Polyciliate 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 Double-sided, weatherproof cone coating enhances durability
