I have noticed a lot of people like the "I" series speakers. RT55i, f/x500i, cs400i ect.
My questions are
1. What is the difference between the blue "I" series and the black non i series?
2. Other than the driver is there any difference? like the crossover or the tweeter?
Are the drivers interchangeable between say the rt55's and the rt55i's or the rt2000p and the 2000i
3. I am also wondering if they offered an RT5000i package.
I am just curious.
