24-inch 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 up to 80°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

Power rating: Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.
Continuous power rating: Defined as 3dB greater than the AES rating.
Sensitivity: Measured on axis at 1W, 1m in 2π anechoic environment.
Parameters: Measured after unit subjected to pre-conditioning signal.
Xmax: 0.5*(Hvc-Hg) + 0.25*Hg
Xmech: Maximum peak-to-peak excursion before damage.
