Key Features: 

• The Celestion TSQ speakers use a 3 way tuned system to vent and coil the magnet motor that typically operates at 30 degrees cooler than conventional speaker designs.
• 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
