Ok, I know some are already saying not a fair comparison, and I must admit it's true. I'm in the process of changing out my audio, and since all my parts aren't here yet, I'm getting bored and fooling around. Anyway I had a set of RF T1675s in my lowers, they sound good, but I decided since I'm up grading my Focals in the fairing, I will put some in the lowers also. I took the left RF out and replaced it with a Focal 165 CA1, I turned the stereo on, the difference between the right channel, (RF), and left, (Focal) is unbelieveable. the Focal is truly superior. The RF's cost me somewhere around $80, the Focals $100, the Focals are well worth the extra $20. I just wish the Focals were thin enough to go on the inner fairing without altering the glove box, I'd put them there also.
