This sub is very good looking and doesn't take too much space if you plan to use it in a living room. If you sit at least 5 ft away from it, it adds a decent amount of depth to the sound of your bookshelf speakers. However, the sub's front firing which makes it not ideal for near-field use, unlike side-firing subs like the KC62. Also, the tuning options for this sub is extremely limited -- you get 3 EQ settings (in-room, wall/cabinet and corner). It doesn't offer parametric EQ to tune for a flatter response. TL;DR If you have an AVR that offers parametric EQs for subs and plan to use it in a living room, this sub is good. However, if you plan to use it near-field, or your speakers have limited tunings to begin with, this sub isn't for you.

Setup was super easy, and getting it to blend with the LSX II LT didn’t take much effort. Once dialed in, it just disappears into the system in the best way. The bass is tight, clean, and controlled, not that boomy kind that takes over everything. It fills in the low end so naturally that tracks feel more complete without losing clarity in vocals or instruments. For music, this is where it really shines. You start noticing details in bass lines and subtle low frequencies that just weren’t there before. It adds weight and warmth but still keeps things precise, which I love. Even when pushing the volume a bit, it stays composed. No muddiness, no distortion, just clean low end doing its job quietly in the background. Open box condition was basically like new, so that made the whole thing feel like an absolute win. If you’re pairing this with something like the LSX II LT for music, this is one of those upgrades that instantly makes you smile.
