The Dinaburg C2S™ Alignment is a unique approach not only to packaging a passive radiator in a small volume, but it also reimagines the traditional approach by repurposing previously discarded energies within the speaker itself. Rather than allowing this energy to go to waste, we harness it, and redirect it towards enhancing the listening experience. The result? Unprecedented sound quality with minimal distortion while significantly reducing energy consumption.

The Dinaburg C2S™ design is not producing any unusable or unwanted acoustic energy compared to the passive radiator design.
Simulation vs Measurement (500-8kHz)
The measured Dinaburg C2S™ polar plot matches very closely to the COMSOL model.

Dinaburg is much closer to the low frequency off-axis response, even at angles up to 60 degrees.
