The rear ports of all the R Series designs, apart from the port-less, sealed-box subwoofer, may be partially or fully blocked as needed to accommodate each speaker’s low-frequency response to your room. To me, it is significantly larger sounding than the space consumed. It's also an EXCELLENT solution where aesthetic _has_ to be a concern. The build, design, and sound quality from this set shows considerable time and engineering resources spent wisely.
Ribs positioned near the tweeter, together with the mid/woofer cone, create what KEF refers to as a “tangerine” waveguide, optimizing the match between the tweeter’s on- and off-axis response and that of the midrange. Delivery times may vary, especially during peak periods. All of the main speakers in the R Series provide two pairs of…um…unique biwirable or biampable binding posts. Instead of the usual strapping bars that connect such posts in other speakers when single wiring is desired, the linkage is internal. Turning external knobs between the posts either connects or separates the terminals. But if you elect to biamp the speakers, be sure to double-check to ensure that you have the terminals separated; unlike those ubiquitous strapping bars, you can’t tell just by looking.

The resulting response is as clean, accurate and distortion-free as a quality conventional speaker, with none of the bulk. With deceptively compact T101s front and rear as well as the centre channel and the discreet T-2 subwoofer, this system is powerful enough to fill most normal rooms with compelling 3D sound. The R600c center employs two 5-inch woofers, one each on either side of its Uni-Q.
In the best center-channel speakers, this is addressed by a three-way design, with a midrange and tweeter positioned vertically between two flanking woofers. The Uni-Q also eliminates this concern, but in perhaps an even more elegant fashion with its nearly coincident midrange and tweeter. While the woofers and the Uni-Q will still be horizontally arrayed, this will normally be less of an issue because of the longer wavelengths involved at the lower crossover frequency between these drivers. If you prefer more frontal 'slam' for movie special effects and a system that generally plays louder, the T205 system has larger T301 speakers for the front satellite and centre channel speakers. The R900s were positioned 9 feet apart and about 5 feet out from my room’s 15.5-foot-wide short wall, directly to the left and right of my projection screen .

The provided spikes were used, but the port plugs were not. The closest sidewall was about 2 feet from the right speaker, and the two speakers were toed-in toward the center listening seat, located about 10 feet from the speakers. The R600c center was placed on a low stand beneath the projection screen, tilted slightly upward. The R100s, used as surrounds in the review system, were located on 25-inch stands near the back of the 25-foot-long room. The R400b subwoofer was placed behind the center speaker and closer to the front wall.
It includes a pair of 8-inch low-frequency drivers, one each above and below its Uni-Q. Metal outrigger feet, with spikes that can be easily tightened from above, provide added stability. The woofers in the R Series are also said to draw from lessons learned during the Blade’s development, both in refinements to the Uni-Q and the R’s seamless, concave aluminum woofer cones. The R400b subwoofer employs a pair of 9-inch opposing woofers linked together internally by a metal rod—a technique also used in the Blade. The T305 system, with T301 satellites and a T-2 subwoofer is ready for anything. For drama as well as music, even in larger loft-like spaces, this has the power to keep everyone on the edge of their seat.

T305 Home Theatre Speaker System
The Uni-Q design is particularly useful in a center-channel speaker. All crossover networks in a loudspeaker cause the response of each driver to roll off gradually above and below their crossover frequencies. Because this results in response overlaps between what are usually physically separated drivers, interference patterns develop off-axis at and around the crossover point. This isn’t generally an issue in a speaker with vertically arrayed drive units, assuming your ears are located at an appropriate height.
The system was driven by a Parasound Halo A51 power amp and an Integra DHC-9.8 surround preamp/processor. The latter’s Audyssey room EQ was not used in the review. The eclectic mix of cables that moved in and out of the system, some of them vintage, some fairly new, were from AudioQuest, Monster, Cardas, and Kimber. The R Series is said to source its technological DNA from KEF’s current $30,000/pair flagship, the Blade. Much of that technology lies in the latest Uni-Q driver, which operates as a virtual point source.
An 80-Hz crossover was selected at the pre/pro when the sub was in use, and the sub’s (non-defeatable) internal crossover was turned to its 140-Hz maximum. All but one of the full-range speakers in the R Series are three-way vented designs employing dedicated woofers and a 5-inch Uni-Q midrange/tweeter. The exception is the small, two-way R100 surround, which has a slightly different 5.25-inch Uni-Q designed to extend its coverage through the bass range. If you’ve been passionate about audio for more than a few years, or can name five loudspeaker companies with names that don’t rhyme with rose and begin with a B, you’ve certainly heard of KEF.
Ditto even if you even simply biwire; leave the terminals connected and accidentally reverse the polarity of one of the biwire leads, and you could trash an amp. The T205 system substitutes a pair of the larger T301 Satellite Speaker for the front satellite, T301c Centre Channel Speakers, and T101 Satellite Speakers, supported by the same discreet high performance T2 Subwoofer.

In the late 1980s, KEF introduced a new concentric driver that placed the tweeter in the throat of the midrange cone. Dubbed Uni-Q, the design has been continually refined for over 20 years and remains the centerpiece of most KEF loudspeakers. Great product - impeccable sound and sleek, great looking form factor. Sound is what you expect fro mKEF which is impressive given the slim profile of these speakers. My impression is only dampened a bit by the fact that my T2 sub did not ship with a power cord.
