Audiomania expert verdict
The most compact Q-series bookshelf with a coaxial Uni-Q (130 mm + 25 mm, aluminium): an even, neutral, “musical” sound for small rooms and shelves — the included plugs let it sit close to a wall. Bass is tidy but “the floor is high” (51 Hz): for electronic music add a subwoofer, for depth take the Q350. 86 dB / 8 Ω: an easy load, but loud listening needs 60 W or more. AI draft, under review

In brief
Best if you are looking for:
- small rooms of 10–18 m² and shelves: “the most compact model in the series”, with the plugs “really onto a shelf” AI draft, under review
- an even, neutral sound “for almost all styles” — “a very pleasant flat spectrum” AI draft, under review
- affordable and older 8 Ω amplifiers: Rotel A10 MK2, Pioneer A-40AE, TEAC AI-101DA — “fit without problems” AI draft, under review
- neighbours and apartment blocks: tidy bass, “absolutely no boom”, plugs included AI draft, under review
- electronic music and rock with a subwoofer — “that is how bass control is achieved” AI draft, under review
Keep in mind:
- “their bass floor is high” (51 Hz): for deep bass — the Q350, ELAC DBR62 or a subwoofer AI draft, under review
- rear port: 30–50 cm from the wall; closer — with the foam plugs (−2 dB at the bottom) AI draft, under review
- ships without grilles — they are an option AI draft, under review
- 86 dB: loud listening in 20 m² needs 60 W or more; at quiet levels the specialist expects less AI draft, under review

Technologies and construction
Uni-Q coaxial driver (130 mm + 25 mm, aluminium)
What it is: A 130 mm ribbed aluminium woofer with a 25 mm aluminium tweeter and tangerine waveguide at its centre, on a common chassis with matched magnet systems.
Practical benefit: “The coherence of a single full-range driver” with the bandwidth of a two-way — owner: “clean highs and a tidy midrange”.
CFD rear port and foam plugs
What it is: A rear-panel reflex port with a CFD profile (smooth airflow); foam plugs are supplied.
Practical benefit: “Very low port noise”; the plugs “turn reflex into sealed, dropping the very bottom by a couple of dB” — so they can sit closer to a wall.
2.5 kHz crossover from selected components
What it is: The crossover is set at 2.5 kHz.
Practical benefit: An even response — “a very pleasant flat spectrum” (owner).
Damped MDF cabinet, three finishes
What it is: A damped MDF cabinet; black, white or walnut finishes; the logo on the top edge of the baffle.
Practical benefit: Compact: “easy to find a place for in the interior”; “build quality is simply superb” (owner).

Recommended power
114–114 W
114–114 W into 8 Ω is the sweet spot; 36–100 W acceptable

4.9 of 5 · 14 ratingsФёдор Ш., Севастополь · 2026-05-05Goodverified purchase
Понравилось, что в комплекте есть специальные "затычки" для фазоинверторов из мягкой губки. С их помощью удалось ослабить низкочастотные резонансы, так как из-за размеров комнаты пришлось ставить акустику к стене ближе, чем рекомендовано производителем.
Владислав К., Одинцово · 2026-03-24Excellentverified purchase
Я думал, что звук будет крутым, а он оказался ультра крутым, это выше всех моих ожиданий!
Сергей З., Пермь · 2026-02-13Excellentverified purchase
Очень замечательная полочная акустика
Владимир П., Нижний Тагил · 2025-09-02verified purchase
Хорошие колонки. Покупкой доволен.
Дмитрий Д., Братск · 2025-02-13verified purchase
Выбирал недорогую акустику, на время ремонта, свои напольные продал, они давали много баса, что очень не нравилось соседям, и эти кеф не разочаровали меня, чуток показалось, они сдержанные по вч, но это от качества фонограммы зависит, в целом неплохо играют в 18 квадратов.
Сергей Р., Нижний Новгород · 2025-01-19Excellentverified purchase
Благодарю, все замечательно!
Андрей П., Омск · 2024-12-18Excellentverified purchase
Великолепная акустика. Играет отлично как с маломощным усилителем (teac AI-101DA), так и с более мощным усилителем на микросхеме TPA3255. Качество изготовления просто великолепное. Очень глубокие басы (в моей комнате абсолютно без гула), чистые высокие и аккуратная середина. Аудиомании отдельное спасибо за быструю обработку заказа, доставку и качественный, абсолютно новый товар (коробка была обклеена фирменным скотчем KEF и без повреждений).
Тимофей К., Москва · 2024-04-09Excellentverified purchase
Удивительно хорошая пара полочников. Для комнаты около 20 кв.м. и усилителя в 60 Вт на канал подошли идеально. Акустику доставили в коробке, опломбированной фирменным скотчем, в кратчайшие сроки и в точно оговоренное время. Прекрасные впечатления от покупки в целом.

Audiomania expert opinion
The Q150 is the classic “first KEF”: the coaxial Uni-Q gives single-driver coherence, and owners hear “a very pleasant flat spectrum” and “clean highs and a tidy midrange”. Specialists call it “more musical” than the Monitor Audio Bronze 6G and happily pair it with a Rotel A10 MK2 or Pioneer A-40AE. AI draft, under review[5]
Honest limits: “the bass floor is high”, so for loud electronic music in 18 m² the specialist suggested the ELAC Carina, for jazz the ELAC DBR62 as “more multi-genre”, and in 12 m² preferred the Radiotehnika S-20N. The Q150 is strong as a neutral compact bookshelf, not as a bass machine. AI draft, under review[4]
