Celestion TSQ1845 Coluna de PA

18" cast aluminium 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 30°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 minimises excess motion and reduces fatigue. Double-sided, weatherproof cone coating enhances durability.
