Ntek OMNI 5” Dodecahedron Source (Rated max 123dB)

Dodecahedron is a sound source used to radiate uniformly a sound in all directions, allowing a correct insulation measurement and reverberation time both in building and architectural acoustics.

Manageability, assembling simplicity and portability are essential requirements for acoustic technicians: OMNI dodecahedron represents the best compromise between weight and portability.

The two versions OMNI 4” and OMNI 5” are designed according to different needs of logistics and power.

OMNI 5” dodecahedron is supplied with a 6 meters connector cable for the amplifier, in order to be moved easily inside the measurement field.
