No,what I was trying to say is some folks have a stricter idea "what works" than other people will have,that's all. I would suggest keeping an open mind and be prepared to consider any/all options. I agree with this,stereo subs can absolutely work very well,but they're not an absolute requirement. Same with ported vs. sealed,there are good & bad examples of both. As someone mentioned: That about covers what I was trying to say. For an experienced "sub guy" it's pretty easy to pick & choose when shopping,for the new subwoofer buyer it's not quite that easy. It just takes some time to study up and figure out what sub(s) will best fit your given needs,and a bit more patience dialing it in. Good luck on the sub hunt. Bret P.
