Bose Acoustimass 10 Series II cracked open Tech 27/01/2014 Audio 2 Comments Photos of the Bose Acoustimass 10 Series II cracked open, as well as a few transparent plexiglass showcase edition. See what’s inside this mighty subwoofer, packing three small woofer speakers, in a weird bandpass arrangement explained in one of the pictures. Tim Koers How do I remove the front panel (the plastic part where the sound comes trough)? I have a bad center woofer, which is located in a room that is far away from handreach. Thanks, Tim Tech I guess the only option would be to try pry it open with a wide flat blade, as there are no screws..
