The TSQ 2145 uses a triple suspension that is laminated with Polysiloxane that retains stability and enhances cone displacement symmetry. Celestion weave the coil lead-out wires suspension to minimise excess motion that in turn reduces fatigue to increase longevity. The 2145 cone uses a double-sided weatherproof coating enhances durability Designed & manufactured in the UK.
