FAQ

What square meter room area is the E3 ST12 speaker suitable for?

Karaoke Speaker E3 ST12 is optimally designed for spaces with an area of about 20 to 30 square meters. With stable capacity, high sensitivity and powerful sound reproduction, the speaker can meet both home entertainment needs and medium-sized business karaoke rooms. In case of use for larger spaces or outdoors, users should combine more subwoofer to increase bass performance.

Do speakers need to be paired with a subwoofer?

Basically, the E3 ST12 is a full-range speaker, so it can still reproduce quite full bass when used independently. However, if users want a deeper and more powerful bass experience - especially with remix, dance, EDM music genres - they should combine it with a 40cm sub bass to enhance the low-frequency effect. This combination also helps reduce the load on the main speaker, ensuring cleaner and more stable sound at high volume levels.

Can I use an amplifier or power amplifier to match the E3 ST12?

The E3 ST12 speaker has an impedance of 8 ohms and high sensitivity, so it is easy to match with many different devices. If used for family karaoke, users can use karaoke amplifier Power from 450W/CH or more. In professional or business configurations, using a power amplifier combined with a digital echo will give better results, especially in terms of detail and frequency control.

Does the E3 ST12 speaker have a harsh sound when turned up loud?

No. Thanks to its balanced low-to-high frequency response and high volume handling (SPL up to 122dB), E3 speaker ST12 still maintains a clear, clean and crisp sound quality when operating at high volume levels. The treble range is adjusted to be bright enough but not harsh, helping the voice to be free and retain emotion - which is very important in karaoke.
