The KEF T305 is the flagship 5.1 home cinema speaker package in KEF’s T Series — a range designed to deliver audiophile-quality surround sound from cabinets slim enough to complement modern flat-panel televisions. The system comprises four T301 satellite speakers for front and rear channels, a dedicated T301c centre channel, and the T-2 powered subwoofer.
Ultra-Thin Cabinet Design
At just 35mm deep, the T301 satellites are among the thinnest high-performance speakers ever produced. This slim profile allows them to mount flush against a wall beside a flat-screen TV or sit on their supplied desk stands with minimal visual intrusion. Despite the compact enclosure, KEF has engineered a genuine two-and-a-half-way closed-box design into each cabinet, maintaining the acoustic performance expected of a dedicated home cinema system.
Driver Technology
Each T301 and T301c houses a pair of 115mm (4.5in.) ultra-low-profile bass and midrange drivers alongside a 25mm (1in.) vented aluminium tweeter developed specifically for the T Series. The tweeter incorporates KEF’s Tangerine Waveguide — a radial channel phase plug that improves high-frequency dispersion by creating a slight compression loading effect, increasing sensitivity and output between approximately 7kHz and 15kHz without requiring additional amplifier power. The result is even sound distribution throughout the listening room, which is critical for convincing surround-sound imaging.
T-2 Subwoofer
The T-2 completes the system with a sealed-box 250mm (10in.) driver powered by a built-in 250W Class-D amplifier. Its compact 380 × 370 × 177mm cabinet is designed to be easy to conceal, yet the combination of driver area and amplifier power delivers bass extension down to 30Hz with a maximum SPL of 110dB. KEF recommends setting the AV receiver crossover to 120Hz when using the T305 system, placing greater demands on the subwoofer’s upper-bass quality — a region where the T-2’s sealed-box alignment provides tight, well-controlled output.
System Configuration
The T305 package includes everything needed for a complete 5.1 surround-sound installation: four T301 satellites handle the front left, front right, surround left, and surround right channels, while the T301c provides a dedicated centre channel voiced to match the satellites. Each speaker can be wall-mounted or placed on its included desk stand, and the T301c can be oriented horizontally beneath a screen or vertically beside it. All speakers are finished in black.
