Well if you read what was quoted above the post. You would see that it says all things being equal a 15 dollar flea market sub will not compare to something that cost 20 or 30x that. What I am saying is that it is possible to make an inferior sub respond better then one would expect. On the flipside, it is also very easy to make a 400 dollar sub respond extremely poorly. Point being, if you don't know what your doing, you are going to have a very hard time accomplishing your goals. Whereas, if you do know what you are doing, you may be able to spend less money and have a comparable system to someone who knows less even though spent more. If you know your **** and you buy higher quality components, why would you not expect better results. I mean you can probably try to find something to nitpick about this so go for it, but this will be my last response.
