Stratus Gold

About the Stratus Gold

The PSB Stratus Gold is a flagship three-way floor-standing loudspeaker introduced in the early 1990s. It features a 10-inch doped paper-cone woofer with a massive 54-ounce magnet and a 2-inch diameter long-throw voice coil, a 6-inch polypropylene-cone midrange with a 28-ounce ceramic magnet mounted in a cast-magnesium frame, and a 1-inch ferrofluid-cooled aluminum-alloy dome tweeter with a unique phase plug design to improve off-axis response and protect the dome. The midrange is housed in its own closed-box sub-enclosure within the cabinet, which is heavily braced and damped to minimize resonances. The crossover frequencies are at 250 Hz and 2.2 kHz, with slopes of 18 dB/octave between woofer and midrange and 24 dB/octave Linkwitz-Riley between midrange and tweeter. The speaker has a nominal impedance of 4 ohms, sensitivity of 88 dB/W/m, and a frequency response of 36 Hz to 20 kHz ±1 dB. The cabinet weighs approximately 95 pounds and measures about 44.5 inches high, 13.5 inches wide, and 14.75 inches deep. It was available in finishes such as black oak, dark cherry, and gloss black. The Stratus Gold is praised for its accurate imaging, balanced tonal response, and ability to play loudly and cleanly, appealing to audiophiles and rock music fans alike. It requires quality amplification due to its low impedance in the upper bass range.
