B-System presents measurement results of the Dryboxx:

Dryboxx is to custom-built in-wall speakers what a carefully engineered cabinet is to high-end floorstanding speakers. Many audio experts agree that the cabinet accounts for up to 50% of a speaker system's overall performance.

We fully share this view. The right cabinet can significantly improve the performance of a custom-built loudspeaker—especially in terms of clarity, dynamics, and bass reproduction.

At the same time, we know that unsuitable enclosures—especially those with insufficient volume—can significantly impair sound quality. Therefore, choosing the right Dryboxx size is an essential part of sophisticated integration.

We have now measured the effects of reducing sound leakage and found that Dryboxx reduces rearward sound transmission into adjacent rooms by up to 30–40 dB at relevant frequencies – a significant improvement in acoustic insulation.

To summarize these findings, we've created a document outlining the acoustic benefits of Dryboxx. Feel free to share it or use it as you see fit. I've enclosed it in German and English.

Dryboxx is an excellent solution for premium loudspeakers – and will continue to be the platform for our developments in this area in the future.

The document can be German and on English can be downloaded and is available in the Downloads from the Dryboxx product page ready for retrieval.
