I have the old red basket tc sounds lms 5400 18" 4hp sub. i'm wanting to make a 12" with the motor. would getting a direct drop in assembly be a problem. would the motor have to be modified to fit the screw holes of the 12"? or like i said would it be as easy as taking the 18" essembly off and dropping in the 12"?
I don't know your goal but why do that when Audiopulse has similiar (and cheap) 1500W RMS drivers in 10's & 12's (LMS) on partsexpress? Then there's Eclipses' 750W SW8200 (LMS/TC motor) & SW8210 (non-LMS w/similiar specs), and Sound Splinters' 2000W RL-S in 12" & 15".
You want a 12" to handle 3k? Why not buy two AP LMS 10's that handle 1500W each, and put it in 3-3.846 cubes NET?
thatts ultimately what i'll end up doing. bought a new commuter car. the 18" wont fit, so I thought no need to not use the motor. dave at psi can make one for 150. still cheaper then buying a new sub. and it would be a nasty little 12 at that.
Stands for Linear Motor Structure, meaning that the BL curve stays constant as the voice coil moves out of the magnetic gap. They increase the factor L, by winding more on the coil so that when the coil moves (and B decreases) L increases which yields the same motor force at all excursion levels.
In my eyes turning a 5400 motor into a 12 is a crime. Won't be much better than a set of 10" lms drivers. sell that motor for some good money and invest in different subs.
I'd buy the whole sub from you in about 3 weeks if you still have it
I used an Eclipse SW8200 on 750W and when there was a constant bass line with kicks during it didn't seem to play them with the same force, it was weaker just like every other sub. Not sure if that's what it's supposed to accomplish. My XXX had more impact with kicks when the kicks were during bass lines.
