FAQ

Is the CAVS SC715 speaker suitable for use in small spaces?

The CAVS SC715 subwoofer boasts a high power output of up to 2800W and a wide sound coverage, making it ideal for spaces of 30-50m² or larger, such as mini stage sound systems , small auditoriums , or commercial karaoke venues. In very small rooms (under 20m²), the bass may be excessive and difficult to control. Therefore, it's not really suitable for small family living rooms.

Does the SC715 speaker have a built-in amplifier or do I need an external amplifier?

The SC715 is an active subwoofer with a built-in 700W continuous Class D amplifier, eliminating the need for a separate power amplifier. Simply connect it to a mixer or digital sound processor, and the speaker will operate independently. This is a major advantage, optimizing space and simplifying the sound system.

Can I adjust the volume and crossover frequency of the speaker?

Absolutely. The rear panel of the CAVS SC715 subwoofer is equipped with a full range of control knobs including volume (gain), crossover frequency, phase (phase inversion), and LED signal indicators. This allows users to easily control the volume, crossover frequency, and adjust it to suit their space and accompanying speaker system.

Does the speaker cause microphone howling if used in a karaoke system?

The answer is no. Because the SC715 is a subwoofer specifically designed to handle low frequencies (38Hz – 150Hz), it does not reproduce high frequencies – the main cause of microphone feedback . If the karaoke system is installed correctly and properly matched, the SC715 will enhance the bass without negatively affecting the microphone or vocals.
