After playing around with the placement, this sub sounds amazing paired with my new KEF LS50 Wireless II speakers. Worth playing around with placement to find the right spot in your space!

The Kube 8b sounds great, I didn't know my system needed a sub, it sounds terrific now. It is a perfect fit with my KEF q350s,Thanks Crutchfield for making me a great offer.

Pros: The KW1 wireless Interconnect really came in handy. And the price can't be beat, free, I love Crutchfield.

Cons: There aren't any.

Great looking and compact. Perfect complement to my setup with a Yamaha AS501 and KEF floor standing speakers. I wanted to fill in the range without overdoing it.

Pros: Easy setup Looks great Lots of headroom - I keep mine at 1/3 volume

Cons: Pricey

New Musical Experience

Crutchfield customer from Renton, WA on 2/11/2020

This is the first real sub I have owned. I have two inexpensive polk subs and pinnacle one that are all boomy and muddy and loud. This KEF sub is the opposite and is great for listening to music. It is accurate, fast, musical, and adds fullness to my KEF bookshelf speakers without overriding any of the 3D lively sound that they provide. A kick drum now sounds like a real kick drum in the room - amazing! I just ordered a 10b in addition to this 8b to replace one of my old polk subs for my home theater. I think that even with action movies I will prefer clean, accurate low sounds to booms and rattles.

Chest thumping bass if you want to fiddle with it. Tight and smooth if you want that. A little pricey. Good for moderate size rooms and jazz

Pros: Small, tight, powerful, tunable

Cons: Chest resonance
