SPL15.3 15" 38cm 2x2Ohm DVC Subwoofer 2500w RMS


World RRP: £361.99

Category: SUBWOOFERS

Product code: SPL15.3.2

The SPL15.3 features many of the same design principles found in the SPL12.2 and SPL15.2 but pushes the boundaries further, increasing the performance significantly. With higher power handling, larger Xmax and much more powerful motor, this woofer has proven very successful in various competitive formats. Triple stacked 125Oz Y35 Ceramic magnets provide a tremendous amount of magnetic force in the voice coil gap. This gives the enormous 4″ VC the force it needs to deliver sledgehammer transients and jellifying bass lines. We’ve kept the basket the same as the SPL15.2, it looks good, it works good. We’ve kept the cone pretty much the same apart from beefed up on the stiffness and where it attaches to the voice coil. The stronger that part of the woofer is, the better it will perform in long duration SPL burps reliably.

Version History


Prototype – We originally prototyped the SPL15.3 in a batch of 10. Tested thoroughly they satisfied our requirements so we put then into production. V1 – The V1 was good. But due to some manufacturing deficiencies and several points for improvement, we moved to the V2. V2 – The V2 looked outwardly the same but with had a taller surround. With a revised voice coil, custom tooled spider ring and dual multi-layer progressive spiders, this new version will had extended Xmax and longer coil height. On the magnet end there were also thicker top and bottom plates. Production of the SPL15.3 was ceased in Q4 2016 to make way for the new SPL15.4 and we retrospectively downgraded the maximum suggested power handling of the model to guarantee reliability of existing installations in the field.
