Woofer: 10-inch (254 mm) cast-frame, high-excursion woofer with treated foam surround (characteristic orange color). Driver complement: 10" woofer and 1" dome tweeter

• Driver complement: 10" woofer and 1" dome tweeter — a classic two‑way arrangement focused on low-frequency authority and clear highs.
• Power handling: Typically rated for ample continuous power for its size (check specific model/serial docs for exact wattage), meaning it can play loud without obvious strain.
• Frequency response: Extends lower than many similar bookshelf monitors, emphasizing bass presence and weight; top end is tuned for clarity rather than extreme airiness.
• Sensitivity: Relatively high sensitivity, so it pairs well with modest amplifiers and plays loudly with less power.
• Impedance: Commonly a nominal 8 ohms, making it compatible with most amps and receivers.
• Cabinet and porting: Sturdy, sometimes ported designs that bolster low‑end output; cabinet resonance control varies by production run and condition.
• Physical size and weight: Larger and heavier than compact monitors—expect a footprint that favors desktop-free setups or dedicated stands.

Physical Dimensions & Weight

• Height: 26.5 inches (673 mm)
• Width: 13.5 inches (343 mm)
• Depth: 11.75 inches (298 mm)
• Weight: 42 lbs (19 kg) each – Heavier than it looks due to the large woofer magnet and dense MDF.

Who it’s for

• Listeners who want lively, powerful sound for rock, hip-hop, electronic, or live recordings.
• Those seeking vintage Cerwin-Vega character and high-efficiency speakers for use with modest amplifiers.
• Collectors and restorers of classic audio gear who appreciate rugged construction and bold sonic personality.
