[QUOTE="audioholic, post: 5125912, member: 549629"] I already explained why, pretty much. When you have two systems running the same frequency band, but not identical systems, they will display dissimilar response curves. So instead of reinforcing each other linearly, as would identical setups, it will get irractic and unpredictable response characterisitics. Some frequencies will be reinforced, some will have cancellation. Over all output to your ears will sound louder generally speaking, as you simply have more cone area for displacement. But if you listen to the system critically, you will notice some notes will be much louder than others, when they should sound the same, for example. You seem to be correcting yourself to say you are after output, not SQ, but then describe a situation where you want a certain type of sound for the low end, and a certain type of sound for the upper bass. These would be aspect in the SQ realm, not the SPL arena. You say your ported system sounds muddy on the top end. Who is to say the 'tightness' you hear in the sealed system will overpower the sloppy sound from the ported, and give an over all pleasing sound? It wont. Subbass is primarily intended to reinforce the front stage, not dominate it or compete with it. IMO you need a better midbass setup in your front stage, and quit expecting your subwoofers to play midbass. Trying to over complicate your substage to attempt to play midbass well, as well as subbass, is just not the right direction to head in. [/QUOTE]
