Krell Modulari Primo Reference Speaker

The Modulari Primo is a 2-way monitor that is a remarkable performer.The 3/4" all aluminum acoustic suspension enclosure eliminates vibration and minimizes wave reflections. The Modulari Primo conveys an image of breathtaking clarity with dimension that belies the simple nature of its design. The 7" aluminum cone woofer includes a proprietary suspension and extended voice coil for high power handling and extremely linear performance. This driver employs cast magnesium-aluminum frame for open, uncolored sound reproduction. Woofer is positioned forward of the tweeter to align the voice coil assemblies and achieve physical time alignment of the drivers. The 1-inch ring radiator delivers flat frequency response to 64kHz.

The crossover is designed to the standards set for Krell amplifier circuitry. Separate crossover network assemblies are used for each driver. All circuitry is on 1/8-inch thick glass epoxy circuit boards with 4 oz. copper traces, ensuring low microphonics, low resistance, low inductance and high current handling. Extensive impedance correction of each driver is applied before the crossover (3rd Order Butterworth 2100Hz). Network inductors are air-core pure copper designs and individually potted polypropylene WIMA capacitors are used in parallel to minimize inductance and resistance while improving current handling. The Primo impedance curve is extremely smooth with a nominal impedance of 4-ohms and a sensitivity of 89dB (1meter with 1W input).

The Modulari Primo is a world class monitor loudspeaker on its own but realizes its full potential when coupled to its companion woofer and becomes a full Modulari Duo Reference. The Modulari Primo sits elegantly, in its dimpled rest area, atop the Modulari woofer tower. United, two separate drive elements come together to reveal a compact full range loudspeaker of unprecedented performance.
