REFERENCE STUDIO ADP-470 v.3 SPECS Model: Reference Studio ADP-470 v.3 surround speakerDimensions: 13W x 12H x 7.9DWeight: 52 pounds per pair 2-way design, 2 x 7 mica-polymer cone bass/midrange drivers, 2 x 1 satin-anodized pure-aluminum dome tweeter, ±2dB 90Hz-22kHz, 8 ohm impedance, 91dB sensitivity, 52lb/pair. Conventional dipole surround speakers have opposed drivers that produce soundwaves out of phase; the result is a diffuse surround sound field. The drawback of dipoles is that because the bass frequencies, too, are out of phase, they tend to cancel each other out, resulting in weak bass response. Paradigm uses what they call an adapted dipole design for their surrounds, running only the woofers in phase, and only below the crossover point of 150Hz, for strong bass performance. They feel that this configuration works best overall, having found that direct radiators are too directional and thus too distracting in most home theaters. The Reference Studio ADP-470 v.3’s subtle wedge shape works well for surround music recordings in which discrete instruments or voices can be heard in the surround channels. The ADP-470 v.3 has two 1 dome tweeters and two 7 mica-loaded polymer woofers, one of each pair on opposite sides of the speaker. The rear panel has holes for wall-mounting hardware and dual gold-plated binding posts. These four-driver, two-way units are enclosed in a symmetric triangulated cabinet, with an identical woofer and tweeter on both the forward and rear faces. The crossover configures them as bipolar below approximately 150 Hz for omni-directional bass, and as dipoles at higher frequencies. The ADP 470s are also capable of being bi-wired or bi-amped, a rare feature for a surround loudspeaker. Grille cloths cover the driver cabinet sides, and the outward facing edges are rounded, making them quite attractive and room décor-friendly. The 12 inches high by 13 inches wide by seven-and-seven-eighths inches deep ADP-470s weigh 26 pounds each, and are available in Black Ebony.
