Hope you dont mind me asking you a question about the Polk speakers you have in your Mobius. Im in the market to upgrade the speakers in my Mobius and Ive been looking at a couple of different models from Polk. What size are they? Model? Do they have the seperate crossover control and if so, how did you mount them? Do you like their performance? What size of amp do you have driving them? Any input would be helpful. Thanks!
