[QUOTE="T3mpest, post: 8178620, member: 560148"] Don't let anyone scare you away from.a 4inch coil. Bigger coils also have higher bl products that generally counteracts the weight and for low bass mass is not a bad thing anyways. The thermal advantages especially st your your power levels outweigh the loss.. my current sub is a 6inch coil and is light enough for 96db per watt per meter rating.. bigger coils up your power handling drastically. Not just taking the power and not burning up but actually using thr power for output. There are many good cooling tricks now on three inch coils but they are still just tricks to eek a bit more out without blowing.. You'll see more gains on music than a burp as music heats the coil more than a 3 second burp.. that burping part of car audio culture is probably where part of the fear of a heavier coil comes from. I know your meterijg but if your looking at 30hz in assuming your mostly into music. If not you could be an easy mid 50 by tuning higher lol. [/QUOTE]
