100db SPL at 1 metre is not very much. The Klipsch KMC-3 is rated 105db at 0.5m, which corresponds to 99db at 1 metre. And it has considerably less Volume than The Beoplay A8 let alone The Sounddock 10. I also included The JBL Authentics L8 in my tests. It is rated 104 db @ 1 metre. Not even as loud as A8, let alone Sounddock 10.

Beolit 15 is powerless compared to A8. Totally different scale. 2 x 35W RMS vs. 2 x 105 W RMS.
