E 90 MK II

K&F E 90 MK II

Concentrated forces

The E 90 MK II is a 2-way passive speaker whose high-performance column speaker design makes it especially suitable for transmission in rooms with difficult acoustics. Column speakers are characterised by a concentration of vertical beam levels. The E 90 MK II already has this effect from 500 Hz, thereby noticeably reducing the reflections from the ceiling and floor. The lean design and technical properties of the system are extremely well-suited for acoustics in churches, lecture halls, sports and multi-purpose halls, community halls and conference rooms. The key difference to conventional point sources is immediately noticeable and impressive. Room acoustic challenges met masterfully!

Aesthetic clarity

The E 90 MK II is suitable for speech and music transmission and provide impressive sound in both low and high-impedance systems. If needed, the K&F subwoofers of the SONA and NOMOS series provide support in the low-frequency range. The system is optically integrated into both historical buildings and also modern glass and concrete architecture. The timeless design particularly appeals to users and architects due to the lean column form and the curved front panel. Looks good, sounds good!
