Popori Acoustics writes: “Our smaller models, the W360, WR2 and WR2 XL are also available in a transparent (TR) version. The disappearance of the cover frame and the modification of the panel structure allow the tuning of the bass range by placing damping sponges.
This highly efficient solution has so far only been available for the WR1 model.
With its help, the frequency response can be customized. It primarily affects the bass range, but the entire frequency range can be fine-tuned. It offers an endless number of options for playful users.”
