Reference Series Model Two (1994-99)
Model Two was a three-way floor standing system with a twin coupled cavity bass section. It offered a significant performance increment over the Model One and was the direct descendent of Model 103/4. It was ideally suited to use as a main speaker in small to medium sized rooms in a stereo or multi-channel system. It was updated in 1997 to include a boundary compensation device – switch-able attenuation of the bass output for use in small rooms or for positioning close to the room boundaries
Model Two Twin bass drivers and advanced,, large diameter force-cancelling rod provide prodigious levels of bass from a surprisingly slim enclosure. The Uni-Q mid and high frequency driver ensures that the sound stage is both wide and deep.
But if, like most people you tend to sit in different places, and want great sound for more than one person at a time, a pair of KEF Reference Loudspeakers will be music to your ears. The Uni-Q Drive Unit with its high frequency driver at the acoustic centre of the Mid-range cone turns the entire room into a "sweet spot".
Music in Minutes, not Hours.
It's the Uni-Q Driver Unit that makes KEF Reference Loudspeakers so simple to position. With ordinary loudspeakers their restricted "sweet spot" means that finding just the right position in your room can literally take hours. Furniture, curtains, walls, ceilings, even the sort of music you're playing can affect how they sound.
KEF Reference Loudspeakers on the other hand, with their ultra smooth off-axis response can be placed, plugged in and played in minutes. After all, it's the music that should be moving you, not the other way around.
Sound Where You Need It Not Where You Don't
It's not just the front of some loudspeakers that give out sound. A badly designed and ill-constructed unit can transmit vibrations through the back and the sides. This unwanted "cabinet Talk" can blur the stereo image and mar the reproduction of fine details.
At KEF we've virtually eliminated this problem in two ways. First, the drivers on the front of the loudspeakers are acoustically decoupled from the cabinet by a soft rubber mounting. And second, the internal bass units are joined back-to-back by a new and vastly improved force-cancelling rod that eliminates much of the vibration that can come from a bass unit and result in the cleanest possible reproduction.
Force-cancelling rods and acoustic decoupling reduce "cabinet talk" dramatically.
