2 perfectly working Kef iQ7SE (Special Edition) speakers Connoisseurs know what these speakers can be and are worth. No dented tweeters etc. with as good as new front covers! Where the new KEF iQ7SE model differs is on the inside, and this is where the engineering excellence of KEF’s acoustic engineers has paid off. With over three decades of acoustic modelling, the expertise of KEF’s engineers has resulted in the redesign of the internal structure and re-voicing of both. Unlike the previous versions, which only used part of the cabinet volume, the new KEF iQ7SE speakers are configured with the Uni-Q and bass drivers working together to take full advantage of the total cabinet volume. To complement this configuration the crossovers have been completely redesigned and upgraded. The result, the KEF iQ7SE deliver a sound stage that is both more exciting and entertaining than before, with their extended bass response and greater overall efficiency. The KEF iQ7SE stand for everything that is KEF, improved dynamics, greater bass agility and more precise timing.
