Project Details

I 3PR is an ultra-compact passive speaker. It consists of a single 3 " cone driver and a passive radiator on the back wall. The proprietary acoustic wave guide design improves the efficiency and directivity of the medium and high frequencies, and the passive radiator extends the low frequency response to 65 Hz. 

The design and modeling concept of the shell was completed by the designer Mr. Stefan Lindfors, who has a wide variety of works all over the world. The injection-molded shell also uses UPM Formi's next-generation bio-based materials. This gives I 3PR not only a unique and timeless appearance, but also strong, light and resonance-free characteristics.  

I 3PR does not have a frequency division function, which results in a completely flat phase response and the most accurate transient response.
