[QUOTE="Buck, post: 8754371, member: 591582"] THIS. Great explanation. I'm trying to design a wall and put a box in a CNC and talk about this at the same time lol. That's so the way I look at it man. You explained my mind better than I did. That's why I was making a reference to low notes. You can over-travel from playing too high in a ported box, but since high notes have less polarity duration, the cones tend not move as much per stroke, before they have to go back the other direction. Low notes and port tuning <--- one of the quickest ways to destroy your woofer is not respecting this relationship. I design my boxes for music almost always; that's what most people want. I design around cone control, largely, and with cone control comes proper frequency bandwidth volume, or leveling, where the woofer is moving more consistently across the bandwidth. Another way to say that: I try to give the sub ton of mechanical air support and loading as it sweeps across a bandwidth. This is extremely important to sound quality and somewhat flatter responses, because some boxes will unload so quickly under tuning that it's easy for the sub to damage itself. It doesn't take much of the bottom of the coil slapping the motor back plate to absolutely destroy a coil and former. It's also very important to control cone movement to limit the variances in impedance and voltage spikes that the amp deals with from the sub movement. When the sub unloads, you run the risk of amplifier problems and dirty signal/distortion problems. I design my boxes, largely, around giving the woofer a home it's happy in, relative to how you want the system to sound. Sometimes you gotta let your woofer stretch before you try to make it run a marathon, you know? [/QUOTE]
