I use 2 of these paired with 2x TS212. They give a Fantastic low frequency sound that can be pushed quite a lot before clipping. Highly recommended!

Great Money To Woof Ratio
Amazing Subwoofer, used it at 6 gigs so far and every one always complements the depth that it adds to the sound, i dont use it fully turned up as i fear i may break the windows or even worse the pint glasses, but this is more than capable of adding that extra spark to your set up, looking at getting a second subwoofer in the new year to add to my set up, well worth the money and such a great service from the guys at, 100% recommend, item arrived within 2 days and was ready for a gig at the weekend.

Absolute beast
This sub kicks out some serious power and really complements the truesonic mid range speakers adding extra bass and depth to dance tracks. Perfect for larger gigs where the extra kick is needed. Despite its power I can lift and move the unit around unassisted with its large grab handles and superb build quality. Would definetly recommend this unit - it's a step up from the 12" and size vs power probably ends up a better solution than the 18"

Great deepness in sound
Purchased an additional sub to go with the package I already purchased so that look was mirror image and to stop me tripping over tri-pods!! Dessent weight but manageable to carry. Build quality is superb and the finish is a nice Matt finish. Additional settings on the back giving you extra low pass which is nice as you can get an even deeper bass.

Great punch for the price
I bought a pair of these and they are a great addition to the pair of TS215's, together they can cope with large venues. Great punchy bass
