My first sub was a KLH. Basically it's bottom of the barrel as subs go. There are two schools of thought on the matter. Some say that it's better to go without a sub than get a crappy sub because crappy subs can be so bad it's not worth it when you can sock away the money toward a quality sub starting at $500. The other school of thought is it would be better than nothing. I lean toward the "crappy sub is better than nothing" and it will help you really appreciate a good sub when you can finally get your hands on one.
