So, I've been concerned about xmax with low frequency signals around 17-20hz at high levels. Often times if I'm pushing too far the cones in my subs will tap the spiders. I've been looking around at other drivers and nothing at the moment is really catching my interest. The talk of a 24 with a strong motor definitely caught my attention, but who knows if and when this will ever materialize. I'm open to any suggestions.

Here is what I've been modeling. Using the same drivers and amps. This is with a 10 cube box tuned to 15hz. Using a 4th order butterworth filter at 13hz to control excursion. This is modeled with 3kw into the vented enclosure and 4kw into the sealed.

And multiplied by 8 SPL:
