XPL15.1 15" 2x2Ohm DVC 3500WRMS SPL SQ Subwoofer

World RRP: £438.99


Product code: XPL15.1.2

So the idea with the XPL range is to deliver an even higher performance sub range in 12″ and 15″ sizes. We did SPL12.3 and 15.3 and learned about spider limitations. We did SPL12.4 and SPL15.4 as an evolution. We then pushed the limit further with the enormous SPL12.5 and SPL15.5. But we wanted more. The remit was a sub that could handle over 3000w RMS and have an Xmax of over 25mm each way. A low Fs as possible while balancing this against the sensitivity so they will still be musical on lower power. Using 4 x XPL prototype woofers we managed an astonishing 159.23 DB at the Swedish DB championships in September 2016. The experience gained from this fantastic result has resulted in the even better, stronger and louder production version XPL hybrid woofer series which manages to be at least a litttle musical as well as SPL competition ready. This is a woofer to be very, very proud of and production is highly limited as the units are hand assembled by a team of just three engineers.

Version History

Prototype - 6 off built specially for evaluation purposes. Used variously including in competition with great success. Noted the need for improved glue on the surround under extreme load and also a slightly uprated spider. VC and magnet fine, basket at limits for SPL. V1 therefore commissioned on this basis with appropriate changes. A tremendous sell out success the XPL15 will be available again at the end of 2018, with exactly the same build quality and devastaing performance. V2 features a newly developed tinsel arrangement for even more durability at the limit and the aforementioned adhesive improvements. Available Q1 2019. Support ended Q4 2022.
