--- IN-DEVELOPEMENT ---

The IVA SiX-26eF is a testament to IVA’s commitment to developing advanced passive technologies aimed at combating echo and excessive reverberation. The “eF” designation is the acronym of echo fighter — our first loudspeaker engineered specifically to deliver clear, intelligible sound in acoustically challenging venues. Designed for deployment in echo-prone spaces such as mosques, churches, shopping mall concourses, and meeting rooms, the SiX-26eF performs exceptionally as an active fullrange loudspeaker.

Its flexible form factor also makes it ideal for use as a front fill, under-balcony speaker, or stage monitor—simply rotate the horn for horizontal placement. The IVA SiX-26eF is the ultimate solution for venues seeking clarity, control, and high quality sound in acoustically demanding spaces.

Passive Echo-Fighting Technology

The SiX-26eF is engineered for acoustically challenging spaces. Its smart design features a built-in 10° downward High-Frequency (HF) bias, which naturally directs sound toward the audience and away from reflective ceilings, even without mechanical tilting. This bias also improves near-field coverage. Combined with a tweeter-between-woofer configuration that tightens vertical mid-frequency dispersion, the SiX-26eF significantly controls mid and high frequencies—the core components of speech clarity—making it one of the most capable loudspeakers in its class for clear audio in highly reverberant environments.
