Here ya go, these are from my BNIB, 1 hour sine wave break in 25Hz @ Xmax,

4.4net @ 26Hz is idea, sub likes 1500 ish daily, dont drop too far below tuning or expect it to bottom out. Excellent SQ from it in that enclosure, cross it at 60Hz and filter it 18dB/oct below tuning and it will please for a long time. Spiders are soft and prone to sag so dont mount firing up if ya can help it. 2" usable throw, high vas low qes means large port area is needed to keep vent mach in check. expect to use 72sq" of port area just to reach .05, but this means alot of air flow into the cabin to stir things up as well. excellent sub for those who can run it properly!
