Maybe used layman terms but the speed the woofer moves does matter - bigger woofers will push more air and will be slower than smaller ones - basic physics. Boominess I meant as in the difference between ported and sealed - sealed tend to be tighter, clearer, more focused than ported which will deliver more boom. When it comes to integrating sub with speakers for music, if your speakers are good the woofers will move fast with precision - its hard to expect 12 or bigger inch subwoofer to be able to keep up with it regardless whether sealed or not.Daka, I believe you have some misconceptions. Faster? It is a sub. It has a frequency response. Most sub drivers can easily produce 300 Hz at X-max. You are crossing them at 80 or so. Do not confuse the mid-bass where the impact comes from with what the sub does. That's magazine reviewer double speak. Poor impact is more often pushing the mains too hard as they don't have the correct high pass filter on them or are just not up to the job.
Ported subs need not be boomy. Only badly designed ones are. We learned this in the early 60's thanks to Theil and Small. Too small a box typically to get a big hump to make the uninformed think they go deeper. Failure to control excursion another common fault. ( Yes, subs should have a HIGH PASS filter on them just as tweeters should have a LOW PASS filter on them.
I do prefer Critical Q subs as they blend with room gain better as second order rather than third, but much bigger. Actually , anything below .7 is OK, A lot won't go below .6 no matter how large the box. Ports big enough for no noise and no resonance issues can get quite impractical. Otherwise BP4 and 6 have some advantages. Just too hard to pull off.
Without doubt general consensus is micro 3000 is tighter, clearer bass than sb1000 pro - and its got nothing to do with SPL at any frequency.
Does that make sense?
