Custom 7-inch Kevlar^® midwoofer sourced from Scan-Speak with specially modified motor structure for Ridge Street Audio Designs. Driver pairs matched to within 0.5 db frequency response.

Custom 1-inch coated silk dome tweeter sourced from Denmark. Specially modified motor structure (for RSAD) and modified rear damping chamber (for RSAD). Driver pairs matched to within 0.5 db frequency response.

Computer Aided Design cabinet. Genuine handcrafted granite. Wall thickness 1.25 inch and damped. (Each speaker weighs approx. 110 lbs).

Proprietary resonance-free RothBoard™ front baffle; 4 inches thick and special rear cavity contour Computer Numerical Control milled along the rear of the midwoofer to eliminate "cavity resonance". Isolated and damped tweeter chamber to eliminate acoustical vibration from the internal enclosure air movement.

Modified QB3 alignment. Bass alignment: Forced laminar-flow vent and adjustable vent Q-factor for room acoustics, amplifier compatibility with ultimate user adjustability.

Proprietary internal bracing scheme to damp the midwoofer basket and motor structure in three dimensions from spurious vibrations.

Hardwired crossover to speaker drivers is "direct wired" using Ridge Street Audio Designs Poiema!!! R-v3 Signature impedance matched wire harness. Wire gauges are 7.5 gauge for midwoofer section with an 18 and 9 gauge combination for the tweeter section.

Pure Connect Direct™ speaker terminals. Signal transmission uninterrupted by conventional binding posts from speaker to amplifier cable. Virtually zero signal loss. Eliminates speaker binding posts and their accompanying signal degrading conduction between the crossovers to speaker cable interface.

Cross-Over is isolated in the dedicated Sason Ltd Speaker Stands to eliminate microphonics in crossover components due to mechanical vibration from the internal enclosure air movement.

Computer Aided Design transfer function in crossover. State of the Art componentry. Acoustically tuned through exhaustive listening. Loudspeaker crossover pairs trimmed and matched to within 0.1 percent. Proprietary circuit treatment. Acoustical and symmetrical 3rd-order slopes for ultimate distortion-free musicality.

Crossover circuitry components are "point to point direct wired". Eliminates the typical circuit board and its losses for optimum signal transmission integrity between components.

Custom air core crossover inductors utilizing "low-tension drawn" construction and 10-AWG high purity copper inductors. Proprietary inductor sealing minimizes dielectric interaction.

Custom film-and-foil crossover capacitors. No electrolytic or metalized-film capacitors in the signal path or shunt positions. The best in signal transfer for not only the tweeter network to tweeter driver interface but also for woofer damping. The absolute for transparency and musicality.

State of the art resistive elements. Ultra low inductance for virtually zero ringing and ultra low TCR for linear stability. No sand-cast or typical wire-wound resistors.

Cryogenically treated crossover wiring and crossover components.

Cryogenically treated Tweeter dome assembly.

Bi-wire crossover architecture for the most undistorted signal transfer possible from source signal to the drivers.

Premium deep gloss automotive level front face urethane paint finishes. Proprietary clear coated for resonance control. Colors are user specified.

High mass polished brass cone points for mounting to stands and with adjustable cabinet tilt-back angle to achieve exacting image control of musical soundstage.

Profiled front face for eliminating typical box sound wave diffraction on the listening axis and off axis (room response).

Optimized tilt-back shape front baffle for proper time alignment between ear, tweeter and midwoofer.
