Studiomaster Vortex 15SA | 2400W 15-Inch Active Subwoofer | UK Stock & Expert Support | djkit®
Staff Take: The Expert Verdict
If you are looking to ground your Vortex top boxes with serious, chest-thumping low-end rumble, the Studiomaster Vortex 15SA is the muscle your rig needs. What really sets this 15-inch active sub apart is its massive efficiency; pumping out a heavy-hitting 132dB Max SPL, it delivers the kind of depth and punch you would normally expect from a much bulkier 18-inch box. It drops the frequency response right down to a solid 43Hz, making it absolutely perfect for mobile DJs and live bands who need to reproduce thick synth basslines or a punishing kick drum. The built-in 24-bit DSP gives you quick control over the low-cut and delay settings, meaning you can time-align your sub with your top boxes in seconds for a tight, punchy sound stage.
