[QUOTE="audioholic, post: 553941, member: 549629"] You misunderstood me completely. Nowhere did I say xmax (actually I used the term excursion, which included xsus) was everything. My point was about air displaced. In my example, when I said if the XXX displaced twice as much, I didnt mean on paper, the specs. I meant in the actual situation. One sub excurting twice as much as two other same sized subs will equal same output. Comparing advertised xmax figures does not answer this variable. Enclosure design, power compression, and many other variables need to be accounted for. As for not all xmax's being equal, and at which frequency it will obtain its advertised xmax, I think you are a bit confused. Different subs do not simply acheive different excursion levels at different frequencies depending on the subwoofer, that is 100% enclosure dependant and irrelevant when comparing drivers. Each driver can be put into an enclosure with the same tuning. And at that point, excursion differences due to freq changes will be the same between the two drivers. SPL subs do not always (or even generally) not extend low. Its true SPL installs do not extend low, but this is due strictly to the tuning freq of the enclosure used being relatively high to match the vehicle's resonant freq, it has nothing to do with the driver used. I guarantee in the proper install, a Stroker, MT, 9500 or SoloX will have zero problem dropping below 20hz. Which would be louder would depend on the enclosure, tuning freq, and power used between the two setups. But yes, as I said in my other post, the SE's have the advantage in output. I did not say otherwise. You said they would be 3db's louder due to double the cone area, that's what I was pointing out that's not true. [/QUOTE]
