I need help on a little mono "FAST" boomless box w. GRS 8PT and 3FE25-4 (or 8 as have both)

I have a single 3FE25-8 and a spare 3FE25-4 for this little (10 liter for the woofer box. Using hornresp for filter examination I get a 0.4 l liter box for 3FE25-4 and minus 3dB down ~250Hz with good power handling at 20 watts input. (will use cheap 3116 mono amp - 20v tool battery)


The lowpass which appears higher in F, and with 150uF caps I have coming is 4.5mH withg two 150uF caps

Will this mess sum OK as is? adjustments ? would there be an advantage to using the somewhat less sensitive 8 ohm 3FE25?

Power handling for 8PT looks good with 20v not hitting xmax and input power dropping fast below 80Hz
