20 foot long speaker cable: is it ok?


Hi guys I'm looking to move my speakers to the long wall of my room, the 14 foot one. In order to do this I'm going to need to acquire a 20 foot pair of speaker cables. I don't (can't) put my amp in the middle.

Based on my research it seems as long as the cable is well made, it shouldn't matter, at least 20 feet or under? I am worried that my sonics will suffer...

I have been using a 24 foot pair of 12 gauge speaker cables for 15 years with various systems in my living room.  Never ever had any problems.  
No big deal. Save your money for real improvements with your components and get some ordinary speaker wire. If you want to go crazy then get 12 gauge wire. The only thing you should avoid is 18 gauge lamp cord or thinner wire. Stranded cables are best because solid cables can be stiff and can cause contact issues and plug or connector strain.
Thanks @stereo5 and @shadorne and @almarg as always you 3 are extremely helpful ☺️

Will be ordering a pair of 20 foot 10g Belden pre terminated cables from BlueJeansCable soon.

I may wind up putting my electronics in the middle of my room, in that case I'd need a 12 foot long power cord as my mains (the only one in my room) is off to the side. Thoughts?
