I hear that the smaller audio companies generally make better subs & cost less than the more popular name brand companies such as Fosgate, Kicker, & ect. However ive never used any of the lesser known brands & cant find many testimonials as to what smaller sub companies make great subs. I am looking to buy a single top of the line 15 inch sub for a decent price. (under $200) Can you tell me your thoughts & experiances on the smaller brands?
