Features:
Design & Build Quality
Crafted with precision, it features a robust structure with 3 units of 4 - inch low - frequency speakers. The cabinet is
constructed from MDF (medium - density fiberboard), paired with a fabric grille. This combination not only ensures durability but also gives the speaker an elegant aesthetic, making it a perfect fit for indoor environments like hotels, airports, shopping malls, and supermarkets.
Audio Performance
Equipped with a full - range speaker unit, the COL - 443 produces well - defined high and low frequencies. It delivers clear,
gentle sound quality, ideal for both speech transmission and background music playback. Boasting a power of 30W and operating at 100V/70V, it has a sensitivity of 93dB and a frequency response range of 130 - 15000Hz, ensuring accurate reproduction of various audio content.
Installation & Practicality
Installation is a breeze, thanks to metal mounting brackets that enable easy and secure wall mounting. A built - in 70V/100V transformer reduces line losses over long distances and allows for convenient parallel connection of multiple speakers. This flexibility makes it suitable for creating comprehensive audio systems in large indoor spaces, meeting the audio needs of different venues efficiently.
