Try Watching Alpine Type R 15" in youtube , get some idea about enclosure
yaar , 4.30 for 1 type R 15" is great
last time i heard ener = R 15" , sound was insane
and even 2 SPLX 12" was much insane then 15"
Type R 15" in 4.3 Cuft @ 40 hz will hit very loud man
is better for 42+ hz notes
, your amplfiier must hit , 1000Wrms , cause type R Magnetic field ( BL ) is very strong , which defines the power handling of the sub
it can handle 1000W easily
but donot exceed
on 4.3cuft enclosure , the Face of port should tilt upwards , so that on upper area under trunk have more space due to trunk length , hence it will make more boom out of trunk
yaar , make Type R , hell loud ,
a task for you , to make Type R loud to demo / impress others
on first time , i heard type R 15" @ absami , not louder as enerlevel
absami system same loud as my current 2x308d2 setup
but as enerlevel prove it , what type R 15" means
Contact ener for consulting
4.3 cuft Ported for Type R 15" tuned at 40hz ,
if you have 1000Wrms @ match impedence thats GOOD
lolz , serious waste of that amplifer on that system , which they dont demand for 1 ohms or even lower
the mono block should run @ 1 ohms and even LESS to give maximum performance , ( inother words to to snatch out maximum WRMS power from amp
