Gorgeous, Compact KEF Sealed Cabinet Subwoofer with Dual 8″ Drivers

From KEF:

“Living proof that a subwoofer doesn’t have to be ugly to thump, the KEF KUBE 1 powered subwoofer is lovely enough to grace a museum – one without noise restrictions. Your guests will be pleasantly surprised to find that your stylishly-modern sub features a 150-watt on-board amplifier and a 8-inch driver backed up by another 8-inch auxiliary bass radiator capable of knocking their wine glasses off its luxurious gloss black top – thereby saving you the trouble of reprimanding the philistines yourself.”

The KUBE-1 has two side-firing 8-inch drivers in a sealed box sitting on 0.5-inch rubber feet. Rated power is 150 watts. The sub is glossy black on the top, with fabric on all sides, including the back, where there’s a metal plate for the minimal control panel.

KEF provides the usual controls for volume, crossover, and phase. The only jacks are stereo line-level inputs—it doesn’t contain any outputs or speaker-level jacks.

KEF was founded in 1961 by former BBC engineer Raymond Cooke, in a Nissen hut on the Kent Engineering & Foundry site in Maidstone, England, which gave the company its name. We carry KEF satellite systems, bookshelf speakers, towers, centre channels and subwoofers. We've had more than 70 KEF listings so far, covering nearly 40 different models. Every used KEF here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.

The KEF models we've sold most often include the HTS1001.2 satellites and HTC1001.2 centre from the KHT1005.2 system, the KUBE-1 subwoofer, the C75 towers and the Q95c centre.

The KEF story, 1961 to today

Raymond Cooke, a former BBC engineer, founded KEF in 1961 in Maidstone, Kent, and named it after the owner of the site, Kent Engineering & Foundry. Its first speaker, the three-way K1, used a tweeter with a Melinex diaphragm, and the compact Celeste followed.

BBC monitors and Reference. KEF drive units were used in the BBC's LS3/5a mini-monitor of 1975, and KEF built it under licence. The Reference Series followed from 1977.

Uni-Q. In 1988 KEF introduced its Uni-Q driver, which puts the tweeter in the centre of the midrange cone, first in the C Series. Uni-Q went on to the Q Series, the KHT satellite systems of the 2000s such as the "Egg", the LS50 of 2012 and the LS50 Meta of 2020.

Today. KEF belongs to Hong Kong's Gold Peak group, through GP Industries, which also owns Celestion, and it is still based in Maidstone.

Which KEF is which?

1960s and 1970s classics: the K1, Celeste, Concord, Chorale, Cantata, Calinda and Corelli.

Reference Series (from 1977): such as the 103, 104/2 and 105, and the Model 100 centre of the 1990s.

C Series (1985 to about 1991): the first C models, then Uni-Q models from 1988, such as the C35, C95 and the C75 tower.

Q Series (from 1990): several generations, including the Q15 to Q95c of 1997 to 2000.

KHT satellite systems (2000s): the KHT2005 "Egg", the KHT1005 and KHT1005.2 (with HTS1001.2 satellites, an HTC1001.2 centre and the KUBE-1 subwoofer), and the KHT5005.2.

T Series (2010) and LS50 (2012 on): the slim T101 speakers for walls and stands, and the LS50 and LS50 Meta.

Buying used KEF: what to check

Satellites need their sub. KEF's small satellites hand the bass to a subwoofer, so buy them with one or make sure you have one.

Uni-Q drivers. The tweeter sits in the centre of the midrange cone. Check the cone for dents, and make sure every tweeter plays.

Subwoofers. Play a KUBE-1 or PSW subwoofer at volume, and check the surround on the KUBE-1's passive radiator.

T Series. The cabinets are only 35 mm deep and were designed for walls or KEF's own stands, so check that the brackets or stands come with them.

Older models. C Series and Reference models are now 35 to 40 years old, so inspect every surround.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
