Sewell Ghost Wire 2.0, Super Flat Adhesive Speaker Wire, 16 AWG, 2 Conductor, 100 ft. Spool, White

I use this for doing audio in places where I have to cross traffic paths. It’s no thicker than gaff tape so it’s almost unnoticeableThe only issue is the connection blocks are a little janky, I tin the speaker wire, and when installing I tape the block and cables down tight. Granted it’s made for home use not what I do, but the stuff is amazing if you don’t want to see or trip on cables

We were renovating and repainting our family room, and my wife agreed to let me put up surround speakers on the condition that there were no visible wires.Unfortunately, on a room with 3 exterior walls, running the speaker wire in-wall was going to be a difficult task. Likewise, wireless options aren't really up to the task if there are no electric receptacles in the area.After reading reviews, we decided to give Ghost Wire a shot. We did some small test samples, about 1-2' long, on a section of the wall where the wire would be run, and painted over it with the color that would be used on the wall. After it dried, my wife said it was minimally visible, and wouldn't bother her, so away I went on installing it.Installation took about an hour per line. I ran it in short sections, peeling off the backing paper as I went, and smoothing it out with a credit card. The adhesive is VERY tough, and not at all forgiving, which was the most trying part of the install, and why I docked it a star. If you make a mistake, paint IS coming off the wall. Changes in direction near corners are particularly difficult because you need to get the angle exactly right, and the adhesive is fighting you the entire time.But once it was up and painted over, it practically disappeared. It is decidedly less visible at eye level and above, and more visible down low. The corners are the only part where it needed extra attention with paint.In all, I'm very happy with the product. It did what it was supposed to, and barring the installation headaches with corners and turns, wasn't bad at all. For a straight run, it would've been no problem at all. Once the paint was up, the only thing left visible was the terminal block. It passed the walkthrough test when my mother-in-law came to see the room and didn't even notice it until it was pointed out to her, and even then she said she still couldn't see it.

Before I begin I will note that I hold a Bachelors in Recording Arts and I studied audio in college. I built audio equipment, and I take it fairly seriously. I wouldn't personally use GhostWire to wire a studio, but this is for an entertainment center.I found this product by accident while searching for a solution to run speaker wire across a floor under a rug in an ultra-low-profile.I did some research and watched a few videos to make sure it seemed to be what I wanted and then ordered a roll and some of the terminal blocks.If you are not getting the terminal blocks then frankly any problems you have are with yourself, this product works beautifully - and I won't lie I kind of had my doubts and thought I was sinking some money into a pipe dream.No this stuff is awesome!The most difficulty I had was in laying straight lines without a guide - something I should have thought to do was mark out my path ahead of time and square it but I was too excited and went straight to taping. Luckily the floor is covered by the aforementioned rug and the wall section by a wall tapestry.The GhostWire is currently powering my rear channel speakers in a 5.1 setup.I am so satisfied I reached out to Sewell to let them know. I intend on using GhostWire for future installations as well.I have not tested how well it takes spackle/drywall mud and paint, since I opted to cover with a wall tapestry as I know I will have to uninstall it eventually.Finally, the tack on this is pretty great. The stick factor is impressive, even dealing with our slightly textured wall like a champ. This stuff is thin, not quite paper thin, I would put it about as thick as two razorblades stacked - tapered at the edges with a gentle slope. This is barely noticeable and before the rug was put down I was able to drag a coffee table over the installed wire without it catching/hanging.Edit 6/20/19: this stuff is still going strong and has even survived the first ten months of my daughters life. It's getting uninstalled soon for a move, but I intend on using this product again when I rebuild entertainment in the new home.
