KEF - KUBE 10 MIE Subwoofer - Black

Super easy to use great sound. Nice construction, beautiful appearance. The actual operating instructions could be a little better or a little more accessible.

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.

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.

We wanted a subwoofer to round out the sound, fill in some nice warm bass, and let our primary stereo speakers (KEF LSX-IIs) focus on what they do best in an office set-up with typically low-volume listening. My home setup pairs a KC62 with these little guys (and I’m in love with it), but it felt like overspend for an office where we would rarely want bass that would carry through to other surrounding spaces. We bought the Kube10 on an open box special and it was exactly what the doctor ordered. Using the KEF App (not always the best interface), the crossover defaults setup automatically (and can be manually adjusted) for the specific subwoofer and I’ve found the listening experience to be massively improved. Would buy again…and again. 5/5 on value at our price. Probably more like 3 (average) or 4/5 in Value at MSRP. 5/5 for all other counts.

This sub is wonderful for my space. It is in a large room paired with kef r5 metas and a Denon avr. Sub makes it all come alive. Highly recommend this kef sub and all kef products.
