If you can hear the sub, then it's too loud. A good friend of mine always has his up a bit, and he complains that he cannot hear mine.... but you sure miss it if I turn it OFF. In my studio I run stereo 15" subs... they make great monitor stands, but they do not call attention to themselves unless the music demands.
Why the fascination with subwoofers?
I have noticed many posts with questions about adding subwoofers to an audio system. Why the fascination with subwoofers? I guess I understand why any audiophile would want to hear more tight bass in their audio system, but why add a subwoofer to an existing audio system when they don’t always perform well, are costly, and are difficult to integrate with the many varied speakers offered. Additionally, why wouldn’t any audiophile first choose a speaker with a well designed bass driver designed, engineered and BUILT INTO that same cabinet? If anyone’s speakers were not giving enough tight bass, why wouldn’t that person sell those speakers and buy a pair that does have tight bass?
