KEF T101 Ultra-Slim Uni-Q Speakers — Satin Black | Impressive!
The KEF T101 is one of the most elegantly resolved flat-panel speakers ever made — a 35mm-deep, wall-hugging satellite that delivers genuine KEF clarity and dispersion from a profile that practically disappears beside a flat-screen TV.
Now discontinued, the T101 was KEF’s showcase for how much performance could be extracted from an ultra-slim sealed enclosure. The answer, as it turns out, is a great deal. The driver complement centres on KEF’s Uni-Q array — a 115mm dual-layer mid/bass driver with a 25mm vented aluminium dome tweeter mounted concentrically at its acoustic centre, fitted with KEF’s patented Tangerine Waveguide. The waveguide controls the tweeter’s dispersion pattern with unusual precision, ensuring that the high-frequency output remains wide and consistent rather than beaming narrowly on-axis as most dome tweeters do at elevated frequencies. The result is a speaker that images well across a broad seating area — genuinely useful in real living rooms where listeners rarely sit in a perfect central sweet spot.
At 90 dB sensitivity into 8 ohms, the T101 is an easy and forgiving load for any AV receiver or stereo amplifier rated between 10 and 100 watts. The 80 Hz – 30 kHz frequency response (-3 dB) is honest and appropriate for a speaker of this size — pair these with a quality subwoofer for full-range performance, or use them as surround or height channels in a larger system where bass management handles the low end.
These speakers are compatible with bare wire or pin connectors. Note: the rear terminals use a press-and-insert clip design rather than conventional binding posts and do not accept standard banana plugs or spades. Our Radique Audio Pin Connectors are a perfect match for these speakers, allowing you to connect heavy-gauge speaker wire cleanly and securely — please see the attached photo.
This pair is supplied with a set of custom metal wall mounting plates. The plates mate to the T101’s integrated 4-way keyhole mount system and are designed to distribute the speaker’s weight across multiple wall screws rather than a single point — a more secure and wall-friendly installation method. Please note these plates are suitable for vertical mounting only; the keyhole geometry means only a single stud can engage the speaker at one time, so horizontal orientation is not supported with this hardware. No additional mounting hardware is included.

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.

PSB VisionSound VS300 Aluminum On-Wall Speaker
An on-wall speaker engineered as one rather than adapted into one. It shares the tweeter, terminals and crossover of PSB's VS400 floorstander, but the port was moved to the front so the cabinet can sit flat to a wall without the wall changing what it does — and a rear switch selects NORMAL or ON-WALL, filling the 400 to 500 Hz dip that hard mounting creates. Extruded aluminium, built in Pickering, Ontario. Graded Excellent or Very Good; the only thing separating the two is a single Tic Tac-sized hole at the extreme edge of one grille frame.
