Enclosure

The Resolution Series loudspeaker enclosures feature a Medium Density Fiber- board (MDF) design. Excellent resistance to vibration is achieved using a minimum 1" thickness of MDF. The baffles of all Resolution loudspeakers are 2" thick, which further damps unwanted resonance. In addition, the liberal use of internal bracing deadens the enclosures. Ideal operating environments for the midrange and tweeter drivers are provided by specialized sub-enclosures that isolate these driv- ers from the resonant effects of the woofer drivers. Large radiuses at the rear cor- ners of the enclosure reduce the effect of internal standing waves, and contribute to the refined appearance of the loudspeakers.

Crossover Design

Each group of driver units (tweeter, midrange, and woofer) has its own dedicated crossover circuit board. Each circuit board is made of double-sided fiberglass and has a number of unique elements. To minimize parasitic inductance and resist- ance, multiple capacitors are connected in parallel, and air-core inductors are wound with oversize wire. This design allows each drive unit to handle its portion of the music signal without strain, maximizes power delivery, and increases signal lin- earity. High-current polypropylene film capacitors are used liberally in the audio signal path.

Similarly, the resistors in the crossover networks are connected in parallel to mini- mize parasitic inductance and maximize current capacity and power dissipation. Oversized, high-power, wirewound resistors are used exclusively.

All the inductors are air-core types; they do not suffer from any of the nonlinearities at low signal levels or saturation at high signal levels that iron-core inductors exhibit. All the inductors are wound with oversize wire, reducing parasitic resistance to a fraction of an Ohm.

RESOLUTION 1 specifications

Krell Industries has long been revered for its high-fidelity audio equipment, and the RESOLUTION 1 speaker is a testament to their commitment to excellence. Designed for the discerning audiophile, the RESOLUTION 1 incorporates advanced technologies and meticulous craftsmanship to deliver an unparalleled listening experience.

One of the standout features of the RESOLUTION 1 is its proprietary bass management system. The speaker employs a unique arrangement of dual 8-inch woofers, each optimized for efficient low-frequency reproduction. This design allows for deep, powerful bass that maintains clarity and articulation, ensuring that every note is rendered precisely. The woofers are crafted from a lightweight yet rigid material, preventing distortion even at high volumes.

The midrange is handled by a custom-designed 6.5-inch driver, tuned to deliver exceptionally natural vocals and instrumental performances. This driver is engineered to minimize resonance and provide a smooth response across the critical mid-range frequency spectrum. As a result, listeners can expect a rich, immersive soundstage that brings music to life with stunning realism.

High frequencies are reproduced by a state-of-the-art ribbon tweeter, known for its ability to produce extended frequency response and exceptional transient response. The tweeter's design allows for a wide dispersion pattern, ensuring that the sweet spot is large and accommodating, so that everyone in the room can enjoy the same pristine sound quality.

The cabinet design of the RESOLUTION 1 is equally impressive. Constructed from high-density MDF and featuring reinforced bracing, the enclosure is engineered to minimize unwanted vibrations and resonance, which in turn enhances audio clarity. The speakers are finished with a luxurious veneer, available in a variety of finishes to suit any home décor.

Connectivity options are plentiful, with the RESOLUTION 1 supporting both single and bi-wire configurations, allowing users to optimize their setup according to their personal preferences. The crossover network is meticulously designed to ensure seamless integration between the drivers, delivering a coherent and balanced sound signature across all frequencies.

In summary, the Krell Industries RESOLUTION 1 speaker represents the pinnacle of audio engineering, boasting advanced bass management, high-quality drivers, and a finely crafted enclosure. Its thoughtful design and cutting-edge technologies make it a standout choice for anyone seeking an exceptional high-fidelity audio experience. Whether for music or home theater applications, the RESOLUTION 1 is poised to deliver sound that resonates with emotion and precision.
