This pair of wall mounts are perfect for ‘bookshelf’ or surround speakers. The original ad says they are rated for speakers up to “13 inches deep, 11 inches wide and 33 lbs”. They worked perfectly for a pair of Klipsch R-14M speakers, which are 3.2 kg (7.13 lbs). They mount to the wall securely and are super strong and allow you to tilt and swivel the speakers to point them where you need. We recently moved and no longer have a use for these - they are in excellent condition. Asking $35 or offers.
