I've been reading about different subs over the past week and I've seen people say sub X is louder than sub Y. How are you able to tell without listening to it? I did a quick search if you can tell by sensitivity and most said that's marketing.
So if I were choosing between the 4 10" subs below, which would be the quietest so to speak. I'm looking for a single 10" to blend in well with my stock JBL system. I'll be using a JL 500/1 V2 to power it and running it at 4ohm.
