Requisite Audio SR71 Silk Dome

The Requisite SR71 is a no compromise studio loudspeaker designed for recording professionals requiring highest-quality audio reproduction in a small format nearfied reference monitor. All materials and components are carefully selected for their acoustical and structural performance. The SR71 is available with passive, active analog (see: SRC2/SRC3) or active digital (see: HPD-3S) crossover options.

Crossover Options
The SR71 is available with passive, active analog (see: SRC2/SRC3) or active digital (see: HPD-3S) crossover options. The electronic analog and digital crossovers offer a path to system expansion from a simple two-way format to a three-way or even four-way system. The digital HDP-3 also allows for “on the fly” selection of 2, 3 and 4-way operation.

Finish Options
Cabinets are made from 1-inch maple/apple ply, painted with durable industrial texture finish. Front and rear baffels are 2-inch maple/apple ply, painted with durable industrial texture finish. Front baffles are also available in custom color guitar finishes. Above photographs show the SR71 in Black Cherry. Color options are almost limitless.

Tweeter Highlights
The large-roll surround and textile dome diaphragm provide a flat frequency response to above 30KHz with outstanding off-axis dispersion. The face plates are die cast in aluminum for a beautiful look with maximum mechanical stability. Unique AirCirc Magnet System – named for the way it optimizes air flow within the chamber – rearranges the traditional magnet structure from a single magnet to an open magnetic circuit comprised of six separate neodymium slugs. This, in combination with the chamber, results in the elimination of the reflections and resonances that compromise the performance of traditional motors. The tweeter gives engineers improved control over critical midrange performance, for superb vocal rendition and excellent imaging at all listening locations.

Mid-bass Highlights
The 7″ Mid/Bass features a non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, “Grasshopper” cast chassis with maximized air flow and resonance terminating mounting system. Less resonance in all structures, lower compression and higher linearity, faster termination of excess energy and higher sound pressure capability. F3 is 50Hz in the SR71 sealed cabinet.
