Audiomania expert verdict
A 2.5-way floorstander with a Uni-Q coaxial driver and two passive radiators: 111 dB maximum SPL, 8 Ω, easy placement. Specialists see it first as a home-cinema front with a mid-class AV receiver; for a purely musical system at the same price they name the Gamma 3.02 and advise an amplifier with headroom.

In brief
Best if you are looking for:
- home-cinema front: “better suited to cinema with effects, explosions and gunfire”; a Q750 + Q150 + Q250c set approved by specialists AI draft, under review
- loud listening: 111 dB maximum SPL — 8/10 by rule AI draft, under review
- mid-class AV receivers: Denon AVR-X1800H, Onkyo TX-NR5009, Pioneer VSX-935 M2 approved; Yamaha RX-V6A — for cinema AI draft, under review
- placement closer to the wall: passive radiators instead of a port — “not critical to placement” by rule AI draft, under review
- classic rock, blues and electronic music with a dynamic amplifier (Audiolab 7000A, Quad Vena II, AMC XIA150se, Luxman L-507u) AI draft, under review
Keep in mind:
- for music the specialist named the Radiotehnika Gamma 3.02 “the highest quality” of the options; with a budget receiver it is “weaker on music” AI draft, under review
- likes power headroom and control: a Marantz PM6007 (45 W) is “too much to ask”, even though the load is easy by rule AI draft, under review
- supplied without grilles (an option) — budget for them if needed AI draft, under review
- owner: the bass was “missing” for the first hours — “after two hours the speakers opened up” AI draft, under review

Technologies and construction
Uni-Q coaxial driver
What it is: A 25 mm aluminium-dome tweeter sits at the centre of a 165 mm aluminium-cone mid/bass driver; radial stiffening ribs and a tweeter waveguide.
Practical benefit: “Coherent, precise sound… an even dispersion”; “a precise stereo image with correct placement of images” (description) — a point source with a wide listening area.
Two 165 mm ABR passive radiators
What it is: The 165 mm woofer (the 0.5 way) is loaded by two aluminium-cone passive radiators either side of it; there is no port.
Practical benefit: “More efficient than a conventional reflex port and raises bass output” (description); no port noise → easier placement near a wall.
2.5-way design, 2.5 kHz crossover
What it is: Uni-Q (bass/mid + treble) plus a dedicated 165 mm woofer; a 2.5 kHz crossover with low phase distortion.
Practical benefit: “Articulate, natural vocal reproduction” (description); the 0.5 way adds bass output without loading the midrange.
Three-section braced cabinet
What it is: Internal braces and partitions split the cabinet into three sections: the top for the Uni-Q, the two lower, acoustically linked, for the bass section.
Practical benefit: A stiff cabinet with separate volumes reduces driver interaction and panel resonance.
Plinth with adjustable spikes
What it is: Outrigger feet extend beyond the cabinet footprint; height-adjustable spikes (323 × 977 × 310 mm — with the plinth).
Practical benefit: Stability and “the necessary mechanical decoupling” (description); parquet needs spike pads.
Amplifier requirements
Recommended power
72–150 W
72–150 W into 8 Ω is the sweet spot; 23–150 W acceptable
Practice band for 25 m² at average level: 50–84 W

From the specialists' experience:
- Passive radiators instead of a port: no port noise, can sit closer to the wall (15–30 cm by rule); the plinth has adjustable spikes — parquet needs spike pads.[3]
- Owner: the bass appeared after a couple of hours — do not judge the low end right out of the box.[1]

Андрей З., Смоленск · 2025-02-02Excellentverified purchase
После первого включения даже огорчился - средние и высокие частоты звучали хорошо, а низы провалены. Но часа через два акустика "разыгралась"- низы пошли. В общем очень неплохо получилось.
Audiomania expert opinion
The KEF Q750 is the most cinema-oriented floorstander in this set: loud (111 dB), 8 Ω, with ABRs instead of a port and a Uni-Q coaxial that, per the description, images precisely. Three specialists approved it with Denon, Onkyo and Pioneer AV receivers. AI draft, under review[6]
For music give it an amplifier with grip — the Audiolab 7000A “suits rock perfectly in dynamics and energy”, Quad Vena II, AMC XIA150se, Luxman; weak 45 W models were rejected by the specialists. If the system is mostly for music, audition the Gamma 3.02 alongside. AI draft, under review[5]
