iQ1, iQ2c, iQ3, iQ5, iQ5SE, iQ6c, iQ7, iQ7SE, iQ8ds, iQ9

2006 saw the release of the new iQ Series, the latest incarnation of a range that had its origins in the late 1980s with introduction of Uni-Q technology. New developments for this series included cabinets with a continuously curved back section, updated drivers for improved acoustic performance and the inclusion of three-way systems in place of the usual 2½-way designs.
 
iQ1 (2006-08)
The successor to the Q Compact - utilising the latest 130mm (5.25”) Uni-Q array.
 
iQ3 (2006-08)
The classic two-way bookshelf with a 165mm(6.5”) Uni-Q - the latest in a series of successful designs going back to the Q10 from 1993.
 
iQ5 (2006-07)
A new three-way design based on a single 130mm (5.25”) long throw bass driver and Uni-Q. With the Uni-Q dedicated to midrange operation the benefits in refinement, detail and precision made this a system of excellent performance for the price.
 
iQ7 (2006-07)
A three-way system based on a 165mm(6.5”) bass driver and Uni-Q array. It offered all the sound quality of iQ5 but with increased bandwidth and dynamics.
 
iQ9 (2006-08)
With an increased internal volume and a second bass driver iQ9 took the performance up another level displaying precise stereo imaging and an even tonal balance together with the dynamic capability to bring across the full power of a music or movie soundtrack.
 
iQ2c (2006-08)
The compact centre speaker based on the 130mm (5.25”) Uni-Q array. Ideal where space is at a premium.
 
iQ6c (2006-08)
The high performance three-way centre speaker with twin 165mm (6.5”) low distortion bass drivers.
 
iQ8ds (2006-08)
A simplified version of the Q2ds dipole surround that maintained much of the performance of the original and the ability to fill the room with ambient energy without distracting the viewer from the on-screen action.
 
iQ5SE (2007-08)
iQ7SE (2007-08)
The SE revision to iQ5 and iQ7 converted them from three-way to 2½-way format to take advantage of the total cabinet volume available in maximizing bass output and dynamic capability. With a fast and lively balance they quickly became a favorite with the magazines and customers alike.
