When shopping for a studio subwoofer, there are many good choices these days, from folks like Yamaha, JBL, Focal, Tannoy, Genelec, and others. Some of the best selling subs are the M-Audio BX10s, JBL LSR4312SP, Yamaha HS10W, Tannoy TS12 and Samson Rubicon R10s. To find the right sub for you, you'll first need to choose between powered (active) and unpowered (passive). Powered subs are far more popular these days because they do not need a separate amplifier like passive subs. A studio subwoofer is generally found in sizes of 10", 12", 15" and 18". Smaller subs will have more "punch" while larger subs will produce deeper and richer bass. Some engineers like to balance the low end by running both a small and large sub at the same time. So we encourage you to check out the reviews on these popular models and see which studio subwoofer you like best.
