  • 2000 W Program Power.
  • 98 dB Sensitivity (1W/1m).
  • High grade Y35 ferrite magnet motor structure with Low interference flux path.
  • Vented chassis and motor design provides 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 designs from 125-400 Litres.
  • Also performs well in appropriately designed horn loaded systems.
  • 4-inch Inside/ outside windings copper voice coil.

The Prime 15XS 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 15XS exhibits 98 dB sensitivity and can deliver bass down to 29 Hz (-6 dB) in a 200

very good sound
ReviewerWalter / Fromnetherlands / Date05 Apr 2017
There is not much to find on the web about this 15" prime. That's why I'm placing this review. Strong build woofer. looking very good. in 2010 I bought two old dual 15" subwoofers loaded with fane colossus from early 90's. The sound was amazing. deep and tight. Much better than most regular subs today (in my opinion). Beacause I wanted more power but with same quality I bought 4x colossus prime 15XS. Put them in the same enclosure (about 200 litre, 2 ports of 3 inch) . I never calculated it. The sound was much better than the old colossus and also much louder. I used a 2x2500w chevin amp. Used it for a couple of years and in feb 2017 I build 4 single 15" enclosures for the prime 15xs (145 litre tuned to 45 Hz). The sound is even tighter and deeper. I'm very happy. I use them with nexo PS10 tops. One 15" is enough for 2 PS10 tops. My conclusion: Very good speaker for bass and subbass applications. There are other very famous brands which maybe play louder and deeper BUT I haven't found any who plays better. If you are looking for quality bass and subbass sound, Prime is the solution. Note: these speakers really need quality power amps, so use high quality amps. I use crown, chevin, crest and lab gruppen. FYI: I also own 4x prime 18XS speakers. also amazing speakers with an earth shaking output. kindest regards Walter Ravensberg (Sassenheim, Netherlands)
Best 15" Sub Ever !!!!

I drive two of these chassis into a chassis. As an amplifier I use the Proline 3000 and WOW. Incredible thomann depth and very precise kickbass. The sound is great even at high levels. The processing of the chassis is synonymous error-free everything neatly glued.

It is a good speaker I know Fane many years I can t tell for how long it will be thomann in good condition it must be tasted only one bad thing it is made in China.
