SPL12.2 12" 30cm 2x4Ohm DVC Subwoofer 1250w RMS

World RRP: £142.99


Product code: SPL12.2.4

Now shipping Version 4 of this product - The latest DVC 4+4 ohm model of the venerable SPL12.2 features an improved voice coil cooling system, increased winding height, bigger bump in pole piece and integrated rubber gasket. the SPL12.2 is a highly developed all round sub with extremes of performance in every respect. Formidable power handling and SPL capabilities, coupled with great sound quality and response characteristics. This sub represents the culmination of years of experience and knowledge, with all the components carefully selected for power and reliability. The non pressed paper cone is lightweight and rigid and has a double stitched oversized surround offering terrifc excursion. The strong woven spider and tough coil former work with the three inch dual voice coil to create a powerful and lightweight motor structure and the insulated tinsel leads are “over under” woven through the spider, offering good performance at large excursions. The cast basket has a low surface area and still manages to be rigid. It also incorporates grilled vents for improved cooling to the VC. We believe that the SPL12.2 is the best speaker in it's class and that it out performs woofers from other brands costing twice as much.

Version History

Prototype – We first had a prototype manufactured in 2011 late on in the year. It made sense that we needed to offer a properly high spec sub. 12″ is the most popular size and all round top performer. The prototype was EXACTLY what we had in mind so we went ahead with the V1. V1 – The first one was one of the best. It featured a few aesthetic things that ones that have been made since do not. V2 – Much the same as the V1 but moved production to a new facility. TS Parameters for this model (& V1) FS:50.14Hz, Sd: 46.38cm2, Mmd:248.91g, Mms:254.65g, BL:25.76T, Qms:6.08, Qes:0.87, Qts:0.76, SPL:84.3w/m, Vas:12.08L, EBP:57.63218391 V3 – Wider spider, marginally longer winding and extra ventilation holes in the T-yoke. We also started building a 2+2 ohm version at the same time. V4 - From assembly date Nov 2016 production of V4 incorporates improved bobbin glue. Outer packaging was also improved with double box and revised inner carton to prevent damage in transit. Deeper and bigger bump in the T-yoke/back plate to enable longer excursion without slapping the plate. Also this meant we could increase winding length safely on the VC +3mm. V4.1 Now with revised retail packaging with gloss finish.
