I went looking around and came across an arm at Monoprice
that has a 200mmx200mm VESA plate to attach to an arm. This particular arm has a weight rating of 85 pounds! This seemed to more than meet the need of the MT-110SR which weigh in at 34 pounds. I purchased the arms. As it turns out, they sat around on the dining room table for a while, but that was out of my hands.
I then went over to PSA's website. I spoke with Tom a bit about arms, told him what I had chosen and asked if he had known anyone to do the same. He hadn't, but that wasn't going to stop me! I asked for a discount code and he graciously obliged. I placed the order on a Sunday (January 14, 2018). Tom let me know via chat that the woofers were on backorder and wouldn't be available for about 5-10 business days. Let me tell you friends, that felt like a lifetime! Ok not really, but I have to keep you interested.
I got to work getting the mounting plate
attached to the speakers
. I needed to find out the minimum height I needed to mount the arms. I took a measurement
from where the plate mounts to the arm to the bottom of the speaker.
After some measurements of the arm, and some math, I grabbed a level and took it to the back of the couch. I used the level to create a mark on the wall indicating the top of the couch. I then measured up to where I wanted to install the bottom of the arm's mount. I found the stud, and drilled a large hole at only the top screw hole of the mount. I put the speaker on the arm and this is what I got
This was way too close to the back of the couch. Someone would definitely hit their head if I left the mount there. Luckily, since I only drilled in the top hole of the arm, all I had to do was unscrew the arm and move it up! That hole became the hole for the bottom of the arm. This moved the arm up 7". It turned out to be perfect
