I bought a second hand 2x12" cabinet with Celestion speakers. The 2 8 ohm speakers were wired in parallel and as I needed 16 ohms so I had to rewire the speakers in series. So I took advantage of the situation and I ordered this speaker cable from the same company that I used before for making my own guitar cables: Cordial.
Well, the result has been excellent. This cable not only is of excellent quality and easy to work with but an improvement in tone. Compared to the previous thin cable in the cab, this one brought out a stronger, cleaner low end, and a slightly more defined mids and highs. Celestion G12T-75 (the speakers in the cab) seem to like the fact that I was using a good quality speaker cable such as the Cordial CLS 240. Recommended for any application but mainly for high wattage applications.
