12inch horn loaded sub build

if u guys didnt see my last build the detials can be found here
https://www.thirdgen.org/forums/car-...pine-type.html
a pair of those played down to 13hz

im not sure what direction im going to go with this build either play as low as possible or as loud as possible

probably as loud as possible

the drivers are some cheap pheonix digital 12's that i picked up for 25 bucks a long time ago right now i have these in a box thats aprox 2.5cft per side with slot ports tuned to 30 or 35 hz , for a cheap sub these things absolutly pound and have tons of excursion


from the specs ive come up with these things should do pretty good in a tapped horn design or even a loaded horn design

im playing with a design right now that should go from 25 to 95 hz and be very efficiant , once i tweak it a lil more ill post up some results and pics

should be later today

My question is; just how long do you expect that pontiac to hold together at 13hz rattling it apart? One cannot hear 13, nor 20, not even 1000 watts can repair the degradation of rolloff. BUT IT SURE FEELS FUDGING GREAT IN THE SADDLE I EXPECT!
