Many of my clients see my bills and I use a section called "misc"...(believe it or not, I get clients who just "write a check") Misc, for me, applies to HDMI, speaker wire and all the other "unknown" till you get there(like blades for a sawzall)... I ALWAYS use fresh saw blades in the sawzall...
So your molding around the sliding door looks out of place? Cordmate(hardly the only brand) is... 1. Paintable. You can choose to match the wall, or the molding. 2. Comes in various sizes/textures. 3. Can either "stick to the wall" with tape or be nailed in.
Speakers don't "put out watts". What matters is efficiency. The current Mini is 90db at 1 watt. I have no idea if that relates to yours. But efficiency and extension are ALL THAT MATTER. Pick a sub, either are going to be "close" to the PDR 10.
