I just sold my new 20-39CS/s700 so that I can take advantage of the upgrade discount to get a 20-39CS+/s1000 which I will order when I get home today. It is my understanding that the CS+ is roughly like 2 CS subs. Now my question is what differences will be noticed when listening. For example, will I notice more bass in movies that I am watching or will I only be able to turn it up louder and have more volume? Or will I have more lower extension at my current listening levels? I would like to see more lower end. Does that mean that I could block one of the ports and then the output would be lower than 20hz. Since it does more I could have more lower end at a higher volume? I guess this is the fundamentals of bass. I am just a newby. I realize the output of the CS+ line is greater. I just want to know how the differences will be noticed. Thanks!!!
