Our versatile C5 compact loudspeaker was the inspiration for the C5i. In the identical weatherproof PU enclosure, the C5i uses a newly developed, inexpensive 5“ chassis with a central dome-tweeter. As with the C5, this coaxial structure results in a radial and ideally homogeneous radiation behavior.

As usual with TWAUDiO products, the focus of the acoustic development with the C5i was also on low distortion and sound quality, but compared to the C5 the performance and the maximum level are reduced by 6 dB SPLmax.

Due to the frequency response-optimized passive crossover, the low-impedance C5i with 6 ohms is also suitable for operation on small standard amplifiers without DSP. Corresponding presets for Dynacord, Powersoft and Lab.gruppen amplifier platforms are also available.

The C5i is predestined for all budget-orientated but high-quality sound reinforcements, which do not require maximum SPL but excellent sound with even radiation.

For example, for near-field applications, demanding background sound systems in bars, restaurants, shopping centers, for smaller conference rooms or for short-throw sound systems in theaters, churches or houses of worship.

All C5 accessories are also compatible with the C5i.

C5i Simply coaxial.
