KEF T305 Home Theatre Speaker System



Slim profile full-sized 5.1 Home Theatre System

Uncompromised home theatre sound without bulky boxes. The T305 system, with T301 satellites and a T-2 subwoofer is ready for anything. The ultimate T Series system has the best of everything: Four T301 front and rear channels with a T301 centre channel, and a T-2 subwoofer with 250W Class D amplifier and 250mm (10in.) bass driver.

KEF T305 5.1 Home Theater System is an exceptionally slim profile speaker that generates all the intricate sound with 3D effect. Enjoy your favourite movie, TV shows and listen to music without compromising space and sound quality.

More importantly, you also want to fill the room with high definition 3D sound that's every bit as involving as what's on screen. With KEF's new T Series, you get exceptionally slim profile speakers that generate all the intricacy, spaciousness and dynamic range of high-end conventional design. You'd expect no less from KEF. With some of the finest speakers in the world to our credit, ours is a 50-year success story of innovation that includes the unrivalled experience of home theatre: multi-award winning systems have for years been the standard by which others are judged.

Easy to conceal and operating in the same phase as the speakers for perfect integration, it delivers fast, uniformly dispersed and devastatingly accurate bass.

T301 Satellite Speakers

In the larger models, the same high performance 25 mm (1 inch) vented tweeter is paired with two 115 mm (4.5 in.) ultra-low profile bass and mid-range drivers for an even bigger sound.

Ultra Slim Bass Driver

At the heart of the T301 satellites is the new Twin Layered Mid Frequency Driver. This revolutionary low profile drive unit is incredibly slim (only 27 mm deep). However, it delivers the performance of a drive unit several times its depth.

Twin Layered Radiating Diaphragm

The T-Series uses a Twin Layered Mid Frequency Driver (patent pending). This is comprised of a moulded radiating diaphragm with integral stiffening ribs running radially and circumferentially. A thin layer of high modulus material on the rear of the ribs provides additional stiffness. This structure ensures the diaphragm moves historically within its working frequency band, whilst occupying a depth of only 5 mm. This technology has been developed and optimised using finite element analysis.

Vented Tweeter

The T-Series has a Vented Tweeter. This increases the amount of air enclosed behind the dome to reduce the distortion of the sound.

Z-Flex Surround

An important feature of the T Series Mid-range Driver is the new Z-Flex Surround. The surround is a critical component of any bass/mid-range driver. The designer must carefully choose the material and shape so as to avoid irregularities in the mid-band response due to resonance in the moving parts whilst at the same time allowing sufficient excursion of the cone in order to reproduce bass frequencies. Most modern drivers use a half-roll design typically moulded from Butyl rubber. The half-roll design can often perform well if carefully designed, however, KEF's computer modelling techniques have allowed us to investigate some more adventurous possibilities. The Z-Flex surround is the result.

T-2 Subwoofer

A slimline closed box design, the assertive T-2 subwoofer completes the 3D sound image by adding definition and weight to the Low-Frequency response.
