Reference Series Models 201, 202c, 203, 204c, 205, 206ds, 207

The 1994 KEF Reference Series proved a major success with good, steady sales all round the world. But after eight years in the market, with only minor modifications to refine the performance, a significant update was in order. This came in 2001, and the differences were clear to see. Curved cabinets, direct radiating bass drivers, a new Uni-Q array with titanium tweeter dome, and a titanium dome ‘hypertweeter’ to extend the acoustic response smoothly into the ultrasonic region. Full AV compatibility was assured with two centre speakers, a premium dipole surround and two powered subwoofers. 
 

Reference Series Model 201 (2001-06)
 
Model 201 was a four-way reflex system for use on a shelf or the dedicated stands, and offered high performance in a compact package in the tradition of well-known KEF designs such as Model 101. It was suitable as a main speaker in small to medium sized rooms or as a surround speaker in systems based around Model 203 or 205 as front speakers.
 

Reference Series Model 202c (2001-06)
 
Model 202c was a four-way reflex centre speaker for use with the 201 or 203 as main speakers. It used the same driver complement as the 203 and continued the tradition of successful, high performance Uni-Q based centre-channel loudspeakers where the uniform dispersion characteristics are key to creating an accurate and natural sound-field over a wide listening area. The bass response was adjustable for TV or free space location and a switch-able  ‘HF lift’ facility was available for those installations where it was used behind a screen. 
 

Reference Series Model 203 (2001-06)
 
Model 203 was a four-way floor standing reflex system primarily for use in free space, but also useable against a boundary with the correct setting of the three position ‘boundary compensation device’. It was the successor to Model 2 and Model 103/4 and was suitable as a main speaker in small to medium sized rooms or as a surround speaker in multi-channel systems based around Model 205 or 207.
 
Reference Series Model 204c (2001-06)
 
Model 204c was an ultimate performance four-way reflex centre speaker for use with the 205 or 207 as main speakers. It continued the tradition of successful, high performance Uni-Q based centre-channel loudspeakers where the uniform dispersion characteristics are key to creating an accurate and natural sound-field over a wide listening area. The bass response was adjustable for wall or free space location and a switch-able  ‘HF lift’ facility was available for when it was used behind a screen. It was designed to complement Model 207 in tonal balance, dynamics and output capability. 
 

Reference Series Model 205 (2001-06)
 
Model 205 was a four-way floor standing reflex system primarily for use in free space, but also useable against a boundary with correct setting of the three position ‘boundary compensation device’. It was the successor to Model 3 and was suitable as a main speaker in medium to large sized rooms or as a surround speaker in multi-channel systems based around Model 205 or 207 front speakers.
 

Reference Series Model 206ds (2001-06)

Model 206ds was an ultimate performance four-way reflex dipole surround speaker for use in the very best home theatre systems. It continued the tradition of successful, high performance Uni-Q based dipole surrounds such as the TDM34DS THX approved model.
 

Reference Series Model 207 (2001-06)
 
Model 207 was a five-way floor standing reflex system primarily for use in free space, but also useable against a boundary with correct setting of the three position ‘boundary compensation device’. It was the successor to acclaimed speakers such as Model 4 and 105/3 and could trace its heritage back to the 105, which was distinctive for its innovative use of modular enclosures. Model 207 was suitable as a main speaker in medium to large sized rooms, in two-channel or multi-channel systems, or as a studio monitor – to which the superior tonal balance and stereo imaging qualities of Uni-Q are perfectly suited.
