  • 2400 W Program Power.
  • 100 dB Sensitivity (1W/1m).
  • High grade Y35 ferrite magnet motor structure with Low interference flux path.
  • Vented chassis and motor design provides efficient thermal management and extremely low power compression.
  • Aluminium demodulation ring.
  • Dual silicone laminated suspension system combined with optimised software materials offers increased linearity for fast, accurate and undistorted bass reproduction at extreme SPL.
  • 12mm Xmax with 64 mm peak-to-peak travel.
  • Fibre loaded, UK manufactured cone offers increased strength, durability and performance.
  • Ideal for bass reflex and scoop enclosure designs from 125-400 Litres.
  • Also performs well in horn loaded systems.
  • 4-inch Inside/ outside windings copper voice coil.

The Prime 18XS 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, a large Xmax of 12mm with peak to peak travel of 60mm, ensures fast accurate bass at high levels of excursion. The cone membrane, manufactured from polycellulose, is much stronger and more durable than conventional paper pulp alternatives. This allows the driver to combine high-sensitivity with the structural integrity required to produce undistorted low frequencies at extreme sound pressure levels. The driver handles 1200 Watts (A.E.S.) continuous and can cope with peaks in excess of 4800 Watts. This is due to advanced thermal management in the form of vented die-cast chassis and increased motor system venting. These measures effectively remove heat from the voice coil, resulting in extremely low-power compression. The Prime 18XS exhibits 100 dB sensitivity and can deliver bass down to 29 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 30 Hz and 300 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.

Operate the driver in a self-built subwoofer with 220 liters and a tuning frequency of about 38HZ. As an amplifier thomann I use the TSA 4-1300 which is by the way top. The bass is very clean and with amazing depth without sounded excessive. The processing is loose, everything neatly glued and cleanly packaged. With 4 pieces you can easily cover most events.
Good Sound
