[QUOTE="audioholic, post: 972042, member: 549629"] As to if excursion affects "SQ", yes it does. Two subs, one with greater excursion than the other, the one woth more excursion will be working proportionally less to acheive the same output. In other words, two subs moving 10mm (which will be equal output.. assuming same cone displacement here for simplicity), one has 20mm xmax, the other has 30mm xmax, the one with 20mm xmax will be working at 50% of its maximum while the 30mm sub will only be working at 30% capacity. 30% versus 50% equals less stress on the sub obviously. This does not mean all subs with greater excursion will inherantly be cleaner, as many other factors are involved (motor topology, etc), but its certainly an advantage. Also, more excursion means more displacement potential which generally equals more low end output, as it takes more and more displacement for lower and lower notes to play at the same output. Some would consider this better "SQ" in the subjective sense. [/QUOTE]
