Electro‑Voice – The ultimate audio brand from America

History of development and global reputation

Electro-Voice, or EV for short, is a famous audio brand from the United States, a member of the Bosch Group. With more than 90 years of development history, EV has affirmed its solid position globally in the field of professional audio. From international stages, large theater systems to family karaoke spaces, this brand is always highly appreciated for its excellent sound quality and outstanding durability.

Technologies that make EV speakers different

Electro‑Voice stands out thanks to the integration of many revolutionary exclusive technologies. In particular, Constant Directivity Horn technology helps the sound spread evenly throughout the space, limiting dead spots. Combined with Signal Synchronized Transducers (SST), EV speakers reproduce sound with extremely low distortion and outstanding detail. In addition, QuickSmart DSP - an intelligent signal processing platform - helps users easily customize the sound quality according to their needs with just a few simple operations on the screen or remote control application.

EV speakers are specialized for performance sound, events, karaoke

With a diverse product portfolio from full-range speakers, subwoofers to professional line-arrays, Electro-Voice meets almost every need. Outstanding lines such as ZLX, ELX, EKX, ETX or EVOLVE are very popular in Vietnam, especially in areas such as high-end karaoke, large halls and outdoor events.

Criteria to know when choosing Electro‑Voice speakers

Space used: small room, stage, hall, outdoor

Choosing the right speaker should start with the space factor. For rooms under 20m² such as family karaoke, models like the ZLX-12P or Everse 8 are ideal choices. Meanwhile, halls with a capacity of 100–300 guests will need speakers like the EKX-12P or ETX-15P to ensure coverage and sound pressure. For outdoor events, the EVOLVE 90 series or line-array systems like the X-Line will be the most optimal solution thanks to their ability to project sound far, evenly and clearly.

Power and coverage: how many W is enough?

Speaker power is the key factor to ensure the sound is strong enough and not lacking in sound. For home use, a power level of 300–500W RMS is enough. For halls or performances, the power should be in the range of 1000–3000W RMS depending on the scale. In addition, the higher the SPL (Sound Pressure Level) index, the clearer and cleaner the sound will be at the same power level.

Active vs passive speakers – which one to choose?

If you want a compact, easy-to-use system without complicated setup, active speakers (integrated power and DSP) are the choice to prioritize. On the other hand, if you are experienced in sound and want flexibility in configuration, passive speakers are more suitable. Electro‑Voice offers a full range of both to serve different user groups.

Connectivity needs & smart DSP features

New EV speaker models all integrate DSP with many presets such as: Live, Music, Speech, Club... to help you quickly adjust according to your usage purpose. Some models also support Bluetooth and app control, providing an extremely convenient experience when used in practice.
