The HTS1001.2 satellite and HTC1001.2 center-channel speaker are identical except for their vertical and horizontal enclosures. The satellite is 6.5 inches tall, but it looks smaller. This might be because of its curved shape and minimal depth. Its cast-aluminum eggshell is two-thirds the size of the satellite in the last egg-shaped KEF we reviewed. If other members of your household are opposed to a 5.1-channel speaker system in a carefully designed room, these attractive yet modest speakers just might meet their requirements for taste and discretion.

Seen from the front, the satellite is oval shaped and tilts very slightly backward from its small base. This suggests a location below the screen. Beneath the undetachable black metal grille is KEF’s Uni-Q “coincident” driver array—the yolk, if you will. Uni-Q is the company’s proprietary name for what is generically known as a coaxial array, with the 0.6-inch aluminum-dome tweeter set into the center of the 3-inch cone midwoofer.

This feature offers several benefits. One is that it saves space. This allows the speaker to be almost miraculously small. Secondly, it provides an audible benefit. The two drivers approximate a point source, so that their respective outputs seem to come from the same place. This reduces phase problems and gives these coaxial speakers a laser-like focus and a more consistent off-axis response. The downside is a modest coloration when the tweeter’s output bounces off the inside of the woofer’s cone. But KEF has had enough practice with this kind of design to minimize the effect.

KEF designed these speakers to be small enough to rely exclusively on their Uni-Q array—with no additional woofers to spoil the symmetry. This adds yet another benefit. The speakers have a total absence of lobing, the effect that can occur in speakers with physically separate drivers. Two-way horizontal center speakers with a woofer-tweeter-woofer configuration most annoyingly demonstrate this. True, the center in this system is horizontal (6.5 inches wide instead of 6.5 inches tall). But otherwise, it’s identical to the other satellites in size, shape, and most crucially, driver position. With just the coaxial array, KEF minimized the off-axis summation and cancellation effects that cause lobing. The speakers feature a consistent dispersion pattern that’s identical across all three front channels. If the coaxial array accomplished nothing but this, it would still be incredibly worthwhile.
