Dayton SD270-88 10" Shielded DVC Subwoofer
reasons i want to change:
1. lower moving mass. my subs are mounted to the deadened rear deck, so lower mms = fewer vibrations/less rattling = purer sound?
2. more cone area. higher sd = less excursion for same volume = lower distortion = purer sound?
3. higher qts. generally a higher qts is better for IB.
the only negative i can think of is the 10" subs have a lower x-max (6mm vs 14.1mm), but i remember reading something about lower x-max woofers sounding better. i ran a quick excursion test by turning the volume up louder than normal with a bass-heavy cd, and the excursion was just under 6mm with my 9Kv.2's.
