Ok I decided I need a new replacement sub. The box from my current sub is perfectly fine and is why I just want to replace the driver. Eventually I will build a new and better box for it but right now I just don't have the time. Yes I have box building skills, I have built many sub enclosures for auto throughout the years and know how to use tools:D I haven't lost any fingers yet and plan to keep it that way:p;) I already have some plans in mind on what I will build. Any hoot, my question is have any of you had any experience with this Dayton sub? I researched many subs and this one seemed from the reviews and others around the net as a good sub. I used their speaker guide and this one suits my current enclosure perfectly, and so does the price! And even better yet my fiance gave me the go ahead to buy it if I want it Geez I feel bad about saying she will kill me on some other threads if I buy any more speakers, she is absolutely amazing for putting up with my ass:o Also this is replacing a 10 year old sub. So any opinions would be greatly appreciated, Thank you in advance, LB!
