Those sold here are very expensive. Any hints on something cheaper (such as from amazon) that work well with my speakers? Thanks!

Don't the QS4's come with wall brackets (the "T-bracket" or whatever replaced it?).

Or are you looking for an adjustable angle bracket like the FMB ?

Skerdi, welcome back. As John B. pointed out, the QS4s are supplied with brackets for mounting flat to the wall. That type of mounting is recommended in most cases since the speakers don't have to point directly at the listener's ears. If for some reason that you haven't mentioned you want a tilting/swiveling mount, possibly a unit such as this one from MonoPrice may be suitable if it can handle the weight. .

It has been a while since I bought these, did not remember they came with the brackets. Hopefully I have saved them somewhere. John: I am shocked you remember me!
