I bought flat speaker wire to run undercfamily room carpeting.  These were a perfectvwayvto terminate them on each sidec- screwing them into the wall 4" above base board.  Looks very professional for DIY in see tall.

I needed some speaker wire for sound in a local haunted house. I know others would be hooking and unhooking things every night, so I normally use red and black electrical tape around the end wires so folks know which wire goes in to which terminal on the speaker. When I saw this inexpensive wire that was already red and black, I knew it would be perfect.

I solder/tin the ends of the wire to make it easier for folks to hook up, and so far, it looks like they have hooked it up properly every night.

Next time, I think I'll get a thicker gauge of wire, and I'll look for this brand first. Great price.

(The photo is from Linn's Supermarket Haunted House in Des Moines, Iowa. It shows this wire coming out from behind a clown prop at the exist. We hid a speaker behind the clown, playing audio for folks waiting in line outside.)

I needed to run HDMI under carpet.  This was low profile enough so that when walking over the carpet, you can't feel the cable underneath.

Wires work well judging by sound coming from speakers.

The wire was used to connect the set of vintage hi-fi speakers.
I actually noticed the improved quality of sound.

Just moved to an apartment and wanted speaker wire that could be hidden under rugs and along walls.  This wire works perfectly for that!  The jacket is extremely flexible and can be bent at 90 angles just fine.  It is also kind of a cream color jacket so it blends well into its surroundings.  The markings on the one side make + to + and - to - connections a breeze.
It is completely invisible under the long area rug I have along a wall.
To expose some wire I simply made a small cut with a scissors not quite 1/2" from the end.  I then twisted the end until the piece of jacket came off and the wire twisted at the same time to allow for installation in the speaker terminal.

Used this to hardwire my upstairs with Cat-5e across two different rooms (router in bedroom, and fed the line through the walls up into the attic and back down to the loft area where the computer area is). Exactly what I needed. I didn't expect to see RJ45 modular plugs attached to each end so if someone needed pre-crimped cables this would work well for long runs...but I cut them off and wired them into a wall plate with a jack in each room. I still have plenty of wire left in case I need to wire other areas of the house too.

Using this for a couple of weeks now to attach computer speakers to TV input across the bedroom (now the sound is right next to me so volume can be turned lower. Now I can hear, and wife next to me and kids in next room are undisturbed at night).  This isn't a super heavy-duty cord, but it's not a cheap or thin speaker wire either (I would classify as medium duty). I certainly expect it to continue to perform since it will remain stationary. Works great, no problems. Good value. Shipped fast. Very happy with this puchase.

i was able to do a very nice custom job of running this along the upper wall and down a section line.  piped my internet to a router in the living room then used the flat cable to go out of the router, through the living room window,  through a water heater door to plate in the wall of the rear bedroom.  i have applications where i simply like cat 5/6 better than wireless. made a custom installation quick, easy, and professional looking.

Because the cable is thin twin-lead, I was able to tuck the cable under the baseboard for a near hidden install of a remote amplified speaker (12V 1A supply).  The cable is flexible and the connectors fit well.  The over-molding provides a grippy surface.

I bought this model because of the almost flat plug so I can put furniture closer to the wall.

This speaker wire is great for speaker runs of most types.  Please keep in mind that this is not meant for in-wall installation as the shielding is not rated for that, but if you are running this along baseboards or under rugs/furniture, it is great!  The sound was clean with little to no interference detected, even when running along side a power source.  The longest I ran this was about 30 ft and it sounded just as good as the center channel at 3 ft from the receiver.

I purchased the 10' cord and am having no problem with having it lay flat. Sadly though, you can't use this UNDER your carpet. They say it can be a fire hazard.

I run this cable under carpet from a PC in one room to speakers in another room. I use all 25 feet and notice no problem at all with hissing or crackles...just normal sound.

I ended up coiling excess cable and using a zip tie to keep it together under my computer desk. I have even stored the excess outside to reduce the clutter under my desk.

I had some cheap speaker wire running between a great receiver and some decent speakers. I thought it sounded okay, but I wasn't really impressed. I bought some of this cable and as soon as I had everything rewired and turned on the system, I could notice that it sounded better. The bass seemed a lot lower and I was happy with the difference. My roommate also noticed the difference as well. Investing in cables is usually a pretty good idea considering how much interference can be caused by a lack of shielding, and how many cables you usually have running out of the back of a system.

Tried both the flat and round. In my case the double shielded round cable gave me a very noticeable difference in reception quality. I'd say if you don't have to install it under carpet get the round.
