Can anyone point me in the right direction for some good quality wall mounts for the 626 ribbons that have the recommended 4" clearance in the back? Am looking for something that will not violate the speaker cabinet, will easily hold the weight, is tiltable, and has a safety strap. For the dipole ribbons, am looking for a wall mount with the same features except would like to hang the speakers flush on the wall. Would appreciate any help.
