The JBL 4406 is a compact, 2-way passive studio monitor designed for near-field monitoring, featuring a 6.5-inch (165 mm) woofer and a 1-inch (25 mm) titanium dome tweeter. Released in the 1980s, it is known for accurate, high-definition sound with a 55 Hz–20 kHz frequency response (±2 dB). These vintage, walnut-finished speakers are prized for their detailed, "tight" sound in restricted spaces. Good cosmetic and working conditions.
