Paradigm, as well as their sister electronics arm Anthem, has long been known for producing components that provide high-end sound at relatively affordable prices. Until fairly recently, Paradigm has offered value-oriented products, such as the excellent Atoms at under $200 per pair, up through the Paradigm Reference Studio 100 v.3 floor-standing loudspeakers that favorably impressed me during my 2004 review. In the tradition of Anthem and their new Statement Electronics, Paradigm has taken on the risky and bold challenge of entering the ultra-high end loudspeaker arena. I was very enthusiastic when, a few months ago, I received a large pallet at my doorstep containing a full Paradigm Signature 5.1 home theater loudspeaker. This included the top-of-the-line Signature S8 main loudspeakers ($6000 per pair), a Signature C5 center channel ($2800), two Signature ADP surrounds ($2300 per pair) and, finally, a Signature Servo subwoofer ($3200).
The drivers utilized across the Signature series are very similar to each other in design and material composition, helping to achieve a synergistic sound from loudspeaker to loudspeaker, and therefore across the 360 degree soundstage. Though I will briefly describe Paradigm’s proprietary Signature transducers, those interested in more detail may reference Paradigm’s informative Signature website for additional specifications. All tweeters are one-inch, Ferro-fluid-cooled G-PAL™ gold-anodized pure aluminum domes. The midrange drivers are MLP™ mica-loaded polymer cones of various diameters, with gold-anodized solid aluminum phase plugs. Each bass transducer features a mineral-filled polypropylene cone and a large one-and-a-half inch voice coil. The S8, C5 and even the ADP surrounds can be bi-amped or bi-wired by removing the included shorting straps connecting the dual pairs of five-way binding posts. Each loudspeaker in the Signature line is available in four high-quality cabinet finishes: Cherry, Natural Birdseye Maple, Rosewood and High-Gloss Piano Black. All of the loudspeakers within this series are designed to perform with the grilles on. These curved, black cloth-covered assemblies are said to eliminate edge diffraction sound reflections that can interfere with a driver’s primary output.
The complete Signature home theater system arrived with absolutely gorgeous high-gloss Piano Black cabinets. Each time I viewed the system, it reminded me of the flawless finish you would experience from a luxury automobile. The Paradigm pedigree is obvious with the S8 main loudspeakers, especially glancing at the Reference 100 v.3s situated next to them in my reference room. The 48.5-inch-high by eight-and-a-half-inch wide by 20.5-inch deep, 100-pound Signatures are, however, a step up in weight, size and most noticeably cosmetics and fit and finish quality. The flawless cabinet rounds and tapers back toward the rear face, leaving a graceful and soft façade from the listener’s perspective. The black finish, slim front face, outrigger feet and appealing aspect ratio also creates the illusion of disappearance rather than an imposing scale that a loudspeaker of this size often can. They are understated but command a powerful presence, eliciting universal oohs and aahs from visitors. The S8 is a six-driver, three-way ported design, with a driver complement from top to bottom, including a one-inch tweeter, a seven-inch midrange and four seven-inch woofers above the relatively small three-inch diameter front port. The frequency response is rated down to 28 Hertz in-room, with the usual uniform +/- 3 degree off-axis horizontal frequency response you expect based on Paradigm’s loudspeaker design philosophy.
The arresting C5 is the largest center channel in the Signature series. It was most often the first thing that caught people' eye as it floated on the optional floor stand below my front projection screen. The 81-pound C5 is the most significantly-sized center channel loudspeaker I have ever had in my home theater, measuring nine-and-a-half inches high by 37.5 inches wide by 17.5 inch deep. This six-driver, three-and-a-half-way design contains a vertically aligned one-inch tweeter and four-inch midrange, flanked by a pair of seven-inch midrange/woofers and another pair of seven-inch woofers. The rear features two high-velocity, low-noise, die-cast aluminum ports to minimize potential distortion from turbulence. The C5 is magnetically shielded via Paradigm’s trademark MagneShield™ technology. Despite its size, once again, the overall feel was graceful because of the gentle tapering from front to rear, the fine gloss black finish and the manner that the optional center channel stand levitated the unit between the projection screen and floor.
Endowed with five drivers, the three-way, triangulated Signature ADP surround loudspeakers are similar in design concept to the Reference series ADPs, and are intended for wall or stand mounting. The side-facing eight-inch woofer is crossed over at 250 Hertz, while the angled front and rear faces each contain a vertically aligned one-inch tweeter and four-inch midrange. They are configured as dipoles, which could be a concern for some multi-channel music sources that are intended to be used with direct radiators to localize musical instruments. The ADPs performed admirably with multi-channel music, which does minimize this concern to a great extent.
Finally, the substantial but graceful 107-pound sealed enclosure Signature Servo subwoofer may be imposing physically (18 and one-quarter inches wide by nineteen-and-a-quarter inches high by 20 and seven-eights inches deep), but it is surprisingly unobtrusive to the eye, largely due to the tasteful curve from the cabinet front to the smaller rear. Realize that this subwoofer is not small and will make a physical statement in your home theater room, albeit a positive one in my opinion because of its stunning cosmetics (my chosen placement was behind the C5). The Paradigm subwoofer insignia glows a soft blue when the unit is powered, but this was not visible or distracting from my listening position because of the sideways orientation I selected. The back panel is comprehensive, with of a variety of useful controls, including excellent graphics illustrating the function of most knobs and switches. Both balanced XLR and unbalanced RCA line level inputs are provided. The low-pass cutoff frequency is continuously variable from 35 to 150 Hertz, and subwoofer-satellite phase alignment from 0 to 180 degrees. The usual subwoofer level dial is included, along with a three-position on/off/auto power switch. The Servo subwoofer is rated down to 11 Hertz DIN.
The first order of business when setting up a home theater loudspeaker system is experimentation with the placement of the main left and right loudspeakers. Leveraging my previous experience in locating the Reference 100 v.3s greatly simplified this process for the Signature S8s. Although I did extensive experimentation with their location, they ended up almost exactly where the 100s performed best, about three-and-a-half feet from the back wall, just over three feet from the side walls, and 11.5 feet from the center listening position. This positioning was chosen as a compromise between low end extension and openness from the upper bass on up, keeping in mind that I had the Signature subwoofer to augment the lower frequency registers. The curved sidewall tapering on the S8s did make it more difficult to eyeball toe-in, so I resorted to exact measurements from side and rear walls to various cabinet corners, something I always end up doing eventually anyway after initial experimentation. The C5 center channel was mounted on the supplied stand and placed below the projection screen along an arc traced through the S8s from my reference location. The Signature Servo subwoofer was situated behind the center channel, as far out from the front wall as possible in a sideways orientation, allowing for convenient control manipulation while optimizing the system. The ADP surrounds were wall-mounted approximately one foot above ear level, and 15 degrees behind the main listening couch. I did not bi-amp any of the loudspeakers, since the robust Anthem Statement P5 power amplifier proved to be more than enough for all of the efficient Signatures.
