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.

Unique in the 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.

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.
