I must strongly disagree with Izzy. The
Sharx (Design: 2-chamber/4 resonators; pealess, Sound Power:
120 dB) is significantly louder than the Fox 40 Micro (Design: 3-chamber pealess, Sound Power:
110 dB).
The "useless bulk" allows for much larger inlet and chambers -- very loud. Per Fox 40, the Sharx has a 10dB advantage over the Micro, and I found it takes less effort to blow.
