They’re speakers known for their “fun” and energetic sound: deep, powerful bass, clear midrange and bright highs thanks to the horn (they can sound bright or “aggressive” in some genres). Ideal for rock, pop, disco, or dynamic music with vintage amplifiers. They’re not the most neutral or refined for pure hi-fi, but they offer great impact and efficiency. If the woofer foams are intact (as they seem), they sound excellent for their age. A rare model on today’s market.
