Anaheim, CA (April 18, 2023)—Celestion debuted its new 18-inch PowerProX18 subwoofer on the 2023 NAMM Show.
According to the corporate, the subwoofer encompasses a cooling design that allows its voice coil to run 20°C cooler than comparable competitor drivers, thus lowering heat-related stress on the 4-inch glass-fiber voice coil former and different thermally delicate components. It additionally reduces the temperature-related rise in Re (coil resistance) that causes energy compression.
Celestion experiences it has recognized adhesives that guarantee extra driver efficiency and sturdiness. In the curiosity of efficiency longevity, particularly in out of doors purposes resembling concert events, the glass fiber-loaded cellulose cone is weatherproofed not solely on the entrance aspect, however on the again as nicely.

With a nominal impedance of 8 ohms, the PowerProX18 subwoofer’s energy score is 1200 watts nominal (AES) and 2400 watts steady. Sensitivity, measured at 1W@1m in 2π house is 97 dB. Its Bl (motor power) curve reveals symmetry, and as a result of cone’s polysiloxane-laminated twin suspension, which gives stability and cone displacement symmetry, the Okay (stiffness) curve additionally reveals symmetry, leading to decreased distortion.
An aluminum demodulation ring reduces the inductance (Le) of the motor circuit—1.61mH at 1 okHz—which additionally contributes to decreasing energy compression. The ring additionally reduces harmonic distortion because the voice coil and cone transfer within the hole towards both pole of the magnet.
The subwoofer has a usable frequency vary of 35 to 1,000 Hz, making it appropriate for giant subwoofer purposes. Xmax is calculated at ±9.3mm. Its chassis helps a 3.5kg ferrite magnet, whereas the general weight of the subwoofer is 13.2kg (29.1lb.)
