HTB2SE-W Subwoofer



Clearly an evolution of the award winning 3000 Series, the new KHT3005SE is the latest version of the iconic ‘egg’ home theatre system, updated to provide an even stronger audio performance with improved clarity and detail yet maintaining the beauty and style that helped make its predecessor a reviewer’s favourite.

The revolutionary Uni-Q driver of the satellite and centre speaker has been enhanced by the addition of the ingenious ‘Tangerine’ waveguide, for improved sensitivity and sound dispersion and have been comprehensively engineered for an even cleaner, smoother response.The cast aluminium enclosures are shaped to minimise internal resonance with KEF’s Sealed Suspension Technology - SSTTM (patent applied for) dramatically improves sound quality and at higher volumes filling the room with incredibly detailed 3D sound.

Carrying up to 60% of the sound, the centre channel is vital in any home theatre system, and the dedicated centre speaker is in a class of its own providing an amazingly clear dialogue in perfect timbre with the satellite speakers.

At last – a handsome, potent, high performance wireless sub that combines outstanding acoustic integrity with complete freedom from interference.

Packing a formidable array of KEF’s revolutionary wireless technologies, the distinctive and surprisingly compact ABS enclosure of the HTB2SE-W 250W houses a Class-D amp driving a 10in. (250mm) LF driver and a matching passive bass radiator. In addition to experiencing visceral bass punch while retaining the delicacy to convey subtle effects with unerring accuracy, HTB2SE-W gives you all the convenience of wireless operation: no cables to embed or trail across the room, and no complicated set-up. With SmartBass™ functionality, your system will be operational in minutes.

Most important of all, KEF’s advanced signal transmission and processing technologies eliminate unwanted mutes, dropouts or loss of bonding as well as interference from your other electronics. Placed horizontally or vertically, in pride of place or hidden away, all you hear is what the artist intended.
  • No interference from other electronics
  • CD quality sound
  • Place anywhere you have a power socket
  • No audio cables trailing across the room

Aluminium dome tweeter with ‘tangerine’ waveguide

The unique ‘tangerine’ waveguide delivers a smoother, clearer high frequency response with an even wider dispersion as well as providing an excellent protection from straying fingers.


KEF’s patented ’sit anywhere’ Uni-Q driver places the tweeter in the acoustic centre of the bass/midrange cone (woofer). This allows both woofer and tweeter to act as a single, focused source of sound that is dispersed widely and evenly throughout the room. The practical benefit is that great sound can be experienced from anywhere in the listening environment removing the "sweet spot" effect.

Sealed Suspension Technology (SST)

A patented KEF technology that effectively seals the gap between a moving mid-range cone and tweeter, which has the effect of dramatically improving sound quality, particularly at higher volumes.
