Limited sound good quality and cables

Unfortunately in all three systems, the two speakers on a 3.5mm jack to the subwoofer (amplifier) ​​are connected. After the cable is split to the left or right speakers on each side, only about a meter long. When a speaker I have extended the cable, which for a coaxial cable is not easy but can be done with some skill and solder joints when stripping.

At the recent Edifier Prisma after about a year the right speaker has failed. Troubleshooting revealed that the associated contact on jack is no longer actuated properly. To spare me the new purchase, because this facility is not used too often, I have the right to clamped to the left speaker, the still works. Became Although only MONO and annoying but it works.

Sound and looks are my claims otherwise perfectly fine. In principle, I would recommend the district, c (n).
