I use Sanus stands, the steel series, rated to 35 lbs (very conservative, IMO... they are steel tubes) , and Pinpoint AM40B wall mounts, rated for... 50 lbs (according to Amazon listing... had to check) with HSU HB1 mk 2 speakers, which weigh 14 lbs. May seem like overkill, but I wanted to purchase the right tool the first time.
There is a very similar wall mount, the VideoSecu MS56B, for about half the price of the Pinpoints, that looks identical, and lists a weight rating of 55 lbs, according to the Amazon listing, but I have no direct experience with it. If I recall correctly, it uses 2 bolts, versus 3 for the Pinpoints. I did test the ones I used, after putting them on the wall, by hanging from it, so I know mine will hold 180 lbs
, at least temporarily. I don't recommend that... I just wanted to know. I like overkill, but , of course, YMMV.
