no experience with the se, but with the sx is where it gets odd lol.
niche audio na6000d (2400 rms at 1 ohm)+12"sx in 3 cubes at 32 hz= 139.x at 35 hz or so
rd audio 2200.1 (1500ish at 1 ohm) tc9 (with out recone) in folded horn t0line=138.7 at 45ish hz.
probably install dependant. but being as how the FI q is just a step above the sx i'd say it would be right on par with an sx. it wooudl certainly have stayed in the car had i not found the oz sub.
I am looking for something that can sound good yet at them same time play high volumes without break up....where you running it for SPL like number ......Been there done that but thiis for a console enclsoure ment to replace a stock console.
it depends on which tc9 motor you have. i emailed him as well and discussed it over the phone. according to him the coil will do just fine in this motor. also when the spiders break in a bit the fs is slightly higher. they don't make it useless as a daily aplication.
nice sub. i wanna get one of the newer tc9 motors with triple stack mags //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
