I was looking to upgrade my entry level home studio (that I also use - to be fair, primarily use - for gaming and music consumption). With SSL2+ and JBL 305P MkII, I was just looking for a lot more bass. Since the JBL sub is a lot, lot more expensive, this seemed to be a good choice. And it was! It does the job, you can set it up the way you want, it has a decent choice of settings. Since I live in an apartment, I only needed a bit of bass to balance my sound (happy to be considerate, dear neighbours), so I have it cranked down quite a bit, but it still delivers bass you can hear and feel and most of all, enjoy. BIg thumbs up for serving my needs more than good enough at a very, very reasonable price (especially compared to other subs)!
Also, if you're a moron like me, and 'accidentally' switch the AC setting (voltage) while plugged in and burn the fuse, there's a spare one under the power socket. I was amazed!
