    Nope. They played with 4" coils on prototypes (basically TRF motor/TC 4hp), but found that the efficiency of 3" was worth more than the added power handling of 4".

    The reason most companies don't do a production 4" coil on a 12" is that with most off-the-shelf baskets you lose a bit of excursion with standard 8" spider.

    Plenty of 3" coil subs that would take the 2500D if you're careful, and really 2500 is fully capable of blowing up a 4" coil.

    no 4" 4 layer coil will take 5krms clamped.

    a rms rating means that power constant for 20+ mins nonstop
    So a super heavyweight wont take 5k?
