Hi, I'm looking at getting a couple of 10" subs for a dual bandpass box that I got from a friend, and I'm not sure which subs to buy. I was pretty much sold on the Fosgate HE2 RFP4210 before reading some of these messages, and now I'm thinking maybe Infinity or Audiobahn. Any thoughts? If so, which models, because I'm looking to spend only about $200-250 for the pair on eBay. Thanks for the advice.
