I bought two LF12N401 in order to re-equip two boxes in which I had two delta 12 (eminence).
I only have one thing to say fishing is huge and it drops down. One can easily get to 35 Hz
High price buy the pair for 500 € I'm really happy with my purchase. I think in 12 "we can not not find a better sub / bass compared to the power.
I installed one in a box from a friend who makes the tuning and I just say it's a really good mind-blowing little jewels.
It is am that the scope of a loudspeaker in 12 "is not great do not think you sound to 20 meters with that dirty masi in small rooms such refreshment football, little dirty is really excellent.
QSC RMX 4080HD over a 2 x 8omhs AC drives.
Finding high price for the 12 "but the result is.
Nothing to say for the 12 "sub that goes down to 35Hz, excellent bass fishing and it's up to medium low.
My advice to really make the most of this speaker to work enter 50 see 55 and 100 Hz tone can be felt that that's working range.
Excellent speaker to complete a body 12.
Only negative point high price.
