Dont see how anyone could reccomend one over the other considering you havent mentioned what you are looking for in a sub.. More spl, or more sq? Also how much power do you have?
Im leaning more towards sq. As far as power goes looking at the AQ2200D, possibly the 3500D depends on a few other things. This will be a major upgrade over what I have now.
If you are leaning more towards sq, then probably the fi q.. If yo uare leaning towards the 3500d, then the hdc. Thats dam near 4kw, the q's wont like that power..
