[QUOTE="helotaxi, post: 2851278, member: 550915"] For what I hope is the last time... A properly designed and built ported system will have all the "thump" of a sealed system and will be louder in the lower bass range at the cost of increased box size. The typical ported prebuilt system is a one note box that sounds like garbage and is not at all indicative of the normal sound of a ported system. The bass that you hear in the club is coming from a ported system. Same with concert setups. Secondly, the size of the cone has nothing in and of itself to do with the "speed" of the woofer. The "speed" is determined by what freq is fed to the sub and the inductance of the voicecoil. There are 18" midranges in the professional audio world that are "faster" than any 8" sub. All cone area determines is the amount of air being moved. More air moved means more output. The result is that a larger sub will be louder than a smaller one with other things being equal. You can equal the output of a larger sub with multiple smaller ones to get more cone area. Blending the sub with a front stage is a simple matter of matching levels and can be done with any size sub. In fact it's really easier to match up a powerful substage to a front stage than it is to do with a weak one. You can always turn the subs down if they are too loud but you can only get a weak setup so loud befroe it hits its limit and won't give you any more output. If you front stage is still louder than the subs at this point you have to turn down the fronts and the max level of the sub ends up being your limiting factor in the volume of the system. [/QUOTE]
