Think I found better alternatives, even more sturdy then the Omnimount 20's from what I have heard.

They support speakers up to 25LBS, and both have 2 different kinds of brackets to support the 2 screw mount design of the 170SE. Now to run home and measure the distance between the two holes and the thread size on the 170's to see if it will fit the Vantage Point bracket. Hope this is the solution! I also contacted Vantage Point to determine the maximum angel these will tilt down towards. Will let you guys know once I get a response.
From reading Amazon reviews, the BSM model will tilt 30 degrees, but I am more interested in the BSME.
