Krell Industries, Inc., is pleased to introduce a new lineup of high -performance loudspeaker systems at the 2003 CEDIA Show. The Resolution Series includes four models for high performance music and home theater systems.
"The development of the Resolution series is a natural extension of our reference LAT series of loudspeakers," said Dan D'Agostino, Krell CEO and Chief Designer. "With the success of the LAT series, the market virtually demanded we expand our speaker offerings. The Resolution Series utilizes the same design principles and techniques that are the foundation of the LAT series. When combined with our Class A, KAV, or Showcase electronics, the Resolution speakers complete a system of stunning dynamics and musical involvement. I believe they are unique in their ability to provide extremely detailed, high -powered reproduction for both music and movie playback."
The Krell Resolution Series features robust MDF construction. The external enclosures are 1 - inch in wall thickness and the baffles are constructed of a unique 2 -inch thick sandwich that eliminates baffle resonance. Midrange drivers are isolated within internally braced sub -enclosures. The curvature of the cabinets is designed to completely minimize the effects of internal standing waves. Internal bracing is aligned asymmetrically to increase cabinet rigidity while further reducing internal resonant modes.
"Starting with the most rigid enclosure possible," Mr. D'Agostino explains, "insures the sound emanating from the speaker is only from the drivers. Any interaction from the cabinet distorts the music and diminishes the listener's involvement."
All models are available in either a black oak or figured sycamore real wood veneer.
High Performance Crossover Networks
All network components are mounted on 1/8 -inch thick glass epoxy circuit boards with oversized 4 -ounce copper traces. This design ensures superior linearity by minimizing circuit resistance and inductance. It also eliminates microphonics and assures high current handling capability. "Typical crossovers act as funnels," described Mr. D'Agostino. "Power delivered by the amplifier is choked off before it reaches the drivers. The breadth and dimension of the music is compressed by the crossover." Mr. D'Agostino continues, "Our experience in designing and manufacturing high power amplifiers is the underpinning of our crossover design. The crossovers behave as if they were extensions of our amplifiers, directing the power to the drivers unimpeded."
Network inductors are all air -core pure -copper designs; in the Resolution 1 the largest of these is formed of 10 -gauge wire, measuring 5 inches in diameter. Multiple individually potted polypropylene capacitors are employed in parallel to minimize resistance and inductance while improving current handling.
In combination with the advanced drive units, the Resolution crossover networks are engineered to provide an extremely smooth impedance curve with high efficiency. They, therefore, present a predictable, nearly ideal load to the power amplifier.
The Resolution 1 employs a total of five drive units in a 4 -way floor standing design. The 1 -inch (25mm) tweeter delivers response to 40kHz. It incorporates a central waveguide for enhanced dispersion characteristics. The single 8 -inch (21 -cm) midbass drive unit features a unique mounting system that decouples the driver frame from the baffle thereby eliminating sonic colorations in the key mid -frequency band. A proprietary suspension and extended voice coil structure assure extremely linear performance. The frame is made of a cast aluminum -magnesium alloy with high efficiency for immunity to thermal compression. The 4 inch midrange driver and tweeter are positioned underneath the midbass driver and arranged with the acoustic center at ear level -a design that optimizes vertical dispersion and delivers highly accurate stereo imaging.
The two woofers are custom -designed 10 -inch (26cm) drive units characterized by a double magnet, long voice coil design. They feature aluminum cones and butyl surrounds. The long -excursion design, capable of greater than 1 -inch peak -to -peak displacement, is highly optimized for vented cabinet performance. As with the midrange drive units, each woofer has a cast aluminum -magnesium alloy frame. The two rear bass ports are precisely dimensioned, flared, and positioned with respect to the bass drive units to eliminate turbulence while providing the correct acoustic loading.
The Resolution 1 also features two pairs of WBT binding posts for biwiring applications and floor spikes for absolute mechanical stability.
The Resolution 1 has a frequency response of 25 -20,000 Hz +/ - 3dB. System sensitivity is 90dB SPL at 1 meter with 2.83V input. The cabinet measures approximately 13.2(w) x 56.0(h) x 17.0(d) inches.
Smaller only in physical stature, the Resolution 2 delivers the same high intensity experience as the Resolution 1. The tweeter is identical to that used in the Resolution 1, while the Resolution 2 employs a single custom -designed 6.5 -inch (18cm) midrange drive unit. The tweeter is positioned above the woofer but below the midrange drive unit in order to optimize high -frequency dispersion characteristics and minimize diffraction effects. The two woofers are custom -designed 8 -inch (22cm) versions of the ones employed in the Resolution 1.
The Resolution 2 also features 2 pairs of WBT binding posts for biwiring applications and floor spikes for absolute mechanical stability.
The Resolution 2 has a frequency response of 28 -20,000 Hz +/ - 3dB. System sensitivity is 89dB SPL at 1 meter with 2.83V input. The cabinet measures approximately 11.6(w) x 46.0(h) x 17.0(d) inches.
The smallest of the Resolution Series, the Resolution 3 is a 2 -way monitor system based on the same engineering principles that distinguish the Krell Resolution concept.
The tweeter is identical to the unit used in the Resolution 1. The 8 -inch (22cm) mid -bass drive unit is optimized for use in a two -way design where demands are placed on the low and midrange portions of the frequency spectrum. A polypropylene drive unit, this mid -bass driver features an oversized voice coil and magnet structure with a proprietary suspension design. This advanced driver design simultaneously ensures extraordinary bass reproduction and outstanding midrange accuracy.
The Resolution 3's vented cabinet features one rear bass port. As with the Resolution 1, it is precisely dimensioned, flared, and positioned with respect to the woofer to eliminate turbulence while providing the correct acoustic loading.
The Resolution 3 has a frequency response of 52 -20,000 Hz. System sensitivity is 90dB SPL at 1 meter with 2.83V input. The cabinet measures approximately 11.3(w) x 16.0(h) x 14.0(d) inches.
Designed to serve as the front -center loudspeaker in a multichannel surround -sound system, the Resolution C, a 3 -way design, features four drive units: one tweeter, one midrange driver, and two woofers.
The drive units are configured for optimum horizontal dispersion. The Resolution C is a dual port vented cabinet housing two high excursion 8 -inch woofers, a 4 -inch midrange, and the same tweeter used in the Resolution 1.
The Resolution C has a frequency response of 45 -20,000 Hz +/ - 3dB. System sensitivity is 90dB SPL at 1 meter with 2.83V input. The cabinet measures approximately 32.0(w) x 11.6(h) x 14.0(d) inches.
"The Resolution series has benefited greatly from our design work on the LAT speakers." said Mr. D'Agostino. "Reference level design work always improves future products and the Resolution series is no exception. The acoustically inert low -diffraction cabinetry, the high -power low -distortion crossover network design, and the high -performance drivers add up to a unique listening experience. Put the Resolution speakers in a system with our music or home theater electronics, and you get sound that I can only describe as pure Krell -as explosive, delicate, and immediate as music itself."
