FROGBRO Witte superplatte luidsprekerkabel, zelfklevend, laag profiel, geïsoleerd, 2 zuivere koperen geleiders, 16 AWG, 6,9 cm breed x 15 m lang, met 2 aansluitingen

Firstly the good bits - this cable does exactly what it says on the tin. I've stuck it direct to a concrete floor, including doing an "origami" fold to do a 90 degree turn, and the cable runs are now 100% invisible beneath the latex screed + hardwood effect flooring that we laid over the top of them. The one thing that did disappoint though is that in various videos of similar products, you get the impression that having pealed back the protective backing, the white surrounding paper would be sticky but the copper strips themselves would not be covered in self-adhesive. However the Frogbro cable is seriously sticky all over, which means that if you intend to do solder you speaker wires onto the end as opposed to using the plastic connectors, you're going to have some difficulty. I've been unable to scrape off or find a suitbale solvent to expose the copper for soldering. The result is that for the final run of standard cable up to the speakers, I'll have to buy some smaller gauge wire, since the screw holes in the supplied plastic cnnector blocks are VERY small. All in all though, it's done the job and I'd use again.

These were the best solution for me as I didn't want to drill in to a concrete ceiling and it's amazing how thin the cables are. The glue is super sticky but still allows you to make one mistake whilst retaining the stickiness.On a white wall/ceiling however, when you paint white over it, it's still visible. I'd imagine with a colour (preferably darker), this will probably hide well.I have no complaints.I don't think you need to buy the connectors as they are too expensive.You're better off connecting existing normal cable to the flat wire via electric tape and secure it well.
