  • Highly versatile in 2-way ported enclosures.
  • UK manufactured cone with optimised pulp offering increased strength, durability and performance.

The Sovereign Pro 18-800P is intended for use as a high-output bass driver in multi way systems and features a 4 inch 'sandwich' inside and outside windings voice coil, immersed in a symmetric magnetic field yielding increased linearity and lower distortion. This, coupled with laminated silicone suspensions ensures fast accurate bass at high levels of excursion. The driver handles 800 Watts continuous and can cope with peaks in excess of 3200 Watts. This is due to advanced thermal management in the form of vented die-cast chassis. These measures effectively remove heat from the voice coil, resulting in extremely low-power compression. The Sovereign 18-800P exhibits 97.5 dB sensitivity and can deliver bass down to 35 Hz (-6 dB) in a 200 Litre ported enclosure.


  • Please enquire about alternative impedances.
  • A.E.S. power handling test. Pink noise bandpass filtered at 12 dB per octave with cutoff frequencies of 35 Hz and 350 Hz. Driver mounted in free air, test signal applied at rated power for two hours.
  • Please note that the frequency response measurements are supplied for comparison only and are not a measure of the low frequency performance which may be achieved in a fully optimised system.
