Proof that bass power doesn’t need to look ugly, the KEF Kube 10b is a handsome subwoofer.

iBX for powerful bass you can feel

KEF’s Kube subwoofers feature iBX (Intelligent Bass Extension) for the deepest bass from the most compact cabinets. The iBX algorithm creates an extended depth of bass that easily exceeds expectations for this size of sub. Backing this up is a powerful 300 watts, Class-D amplifier. This is enough to power the high quality 10" bass unit to high levels and low frequencies. With effortless bass on tap, the Kube 10b is ideal for both movies and music.

Power, controlled
Despite its high power rating, the KEF Kube is about more than just firepower. The sealed cabinet not only offers high levels of rigidity but also gives a tight, controlled bass that's never overblown or sloppy. A 3-position DSP (EQ) control allows adjustment of the Kube's response to compensate for different room acoustics and personal preference. There's also a phase switch. This lets you reverse the phase, giving perfectly timed bass whether the sub is in front or behind you.

Effortlessly stylish
Most subs deserve to be hidden away, but not the Kef Kube! Featuring smooth lines, a wrap-around grille and gloss black top panel, the Kube 10b is one subwoofer you’ll be happy to have on display. As the mid-range model, the Kube 10b is perfect for medium-sized rooms and offers a perfect balance between bulk and bass power.

Sounding as good as it looks, the KEF Kube 10b is a classic all-rounder.

Rated 5 out of 5 by from Sound I bought my KEF KUB 10b with my KEF LSX. The Kube delivers a fantastic bass, I love Piano and most of the times a I think I have a Piano playing in my living room. Listening to R&B and Jazz with the Kube 10 is something amazing.
