im leaning toward cadence because of the price but im willing to pay the extra if rainbow is worth it. i generally listen to rap/hip hop/rock if that makes a difference between what i listed.
as for the hp...
Active Crossover Modules:
These 2-way modules allow you to use separate amplifiers for your subwoofers, midbass
drivers, midranges, or tweeters. By doing this, especially on the subwoofer, a clean and
undistorted sound is available at much higher listening levels.
Each module offers a range of selectable crossover frequencies and 24dB/octave filtering.
• SWX – 60Hz, 80Hz, or 100Hz subwoofer/midbass or midrange crossover.
• MRX – 175Hz, 250Hz, or 350Hz midbass/midrange crossover.
• TWX – 3500Hz or 4500Hz midrange/tweeter crossover.
I have the TWX module on the amp and i believe its set at 3500 HZ. Also the HP on my HU is set at 160Hz so i dont think they blew because of issue with mids. I could be wrong though. If i set the the HP on my HU to 120Hz or lower then my speakers would distort and why i have it set so high and which has led me to believe to much power as i shouldn have to set my HP so high to prevent distortion.
