With \u003cstrong\u003eItalian manufacturing\u003c\/strong\u003e and a particularly discreet cubic form factor, it naturally fits projects seeking a clean visual appearance while maintaining controlled response for daily sound distribution.\u003c\/p\u003e\u003ch3\u003eIntended Uses and Venues\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003epassive speaker\u003c\/strong\u003e is designed for \u003cstrong\u003enearfield sound reinforcement\u003c\/strong\u003e and environments where aesthetics are as important as intelligibility: retail stores, restaurants, hotels, meeting rooms, reception areas, museums, and exhibition zones. Its 4-inch driver favors clear midrange reproduction, helping to maintain \u003cstrong\u003eintelligible vocals\u003c\/strong\u003e and pleasant background music even at moderate volume levels.\u003c\/p\u003e\u003cp\u003eWith a \u003cstrong\u003enominal impedance of 16 Ohms\u003c\/strong\u003e, it suits multi-speaker configurations well (depending on amplification and wiring choices). The manufacturer recommends a \u003cstrong\u003e100 W RMS amplifier\u003c\/strong\u003e for comfortable operation, while the speaker's nominal power handling is \u003cstrong\u003e50 W RMS\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eCoaxial Design, Even Dispersion, and Simplified Integration\u003c\/h3\u003e\u003ch4\u003e2-Way Coaxial Architecture\u003c\/h4\u003e\u003cp\u003eThe Keiron 4C W features a \u003cstrong\u003e2-way coaxial configuration\u003c\/strong\u003e, combining a \u003cstrong\u003e4-inch woofer\u003c\/strong\u003e (1.5-inch voice coil) and a \u003cstrong\u003e1-inch tweeter\u003c\/strong\u003e (1-inch voice coil). This design aims for a more \"point source\" sound with increased coherence between frequency ranges, useful when the speaker is placed close to listeners or in reverberant spaces.\u003c\/p\u003e\u003ch4\u003e90deg x 90deg Coverage and Recommended Filtering\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003e90deg H x 90deg V dispersion\u003c\/strong\u003e facilitates placement to cover an area evenly. The \u003cstrong\u003ecrossover frequency\u003c\/strong\u003e is specified at \u003cstrong\u003e3 kHz\u003c\/strong\u003e. To ensure safe operation in the low-frequency range, a \u003cstrong\u003erecommended high-pass filter at 90 Hz\u003c\/strong\u003e (24 dB per octave slope) is advised, which can be implemented via a processor or digital management system.\u003c\/p\u003e\u003ch4\u003eWiring and Installation\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003eEuroblock input connector\u003c\/strong\u003e with \" \u003cstrong\u003ein \u0026amp; through\u003c\/strong\u003e \" design is intended for installation wiring (feed and return), convenient for chaining to a second speaker.
