Stereo vs mono Subs?

Sorry about that. What I'm trying to say is simply that you are going to hear a difference in component quality over say...your standard pioneer coaxels at best buy. When you combine more extreme subwoofer setups to a nice set of components it is going to be harder to maintain ultamite quality at higher volume levels if you are looking to keep everything balanced. Concluding that you simply can't have both SQ and SPL... I do have to admit there are more woofers and components these days that have represented some good SQL performance. I would only have to further agree that building your setup more towards the midbass direction is better. To me once you cross a certain line on volume level with your woofers, your speakers can't keep the proper quality when being balanced. You are less likely to experience ear fatigue with components.
