New cooling and inductance features that are set up in stages. The first stage is a machined aluminum pole sleeve. This provides better heat wicking and is the first portion of inductance linearizing and reduction. The second stage is a combination of the pole sleeve and an aluminum domed compression cap. This increases the compression ratio for cooling as well as adds some outstroke inductance reduction. The third stage utilizes the pole sleeve, the compression cap, and a thick aluminum finned extrustion that again lowers and linearizes inductance as well as aids in thermal dissipation. With the third stage we have reduced inductance by almost a factor of 3 over utilizing none of the aluminum.

All leads are stitched in the same pattern and use the bolted terminal block as the original hybrid design. But we have added push terminals that use this same setup with the ability to handle much larger wire and completely removing the multiple solder and crimp points that could introduce unwanted resistance.

All Neo4.X subs use the high Xmax dual 1 Ohm and dual 2 Ohm coils for 33mm of one way Xmax.

NEW! Option
Need more motor force and efficiency from a lighter package? Opting for Fi Car Audios Black Neo will up your lower line driver to the next series up in motor force, but keep the lighter series weight.
Need more motor force for crushing lows and compression fighting in the gap Gauss? Opting for Fi Car Audios Black Neo will take your N3.9 or N4.11 to the next level. Generating more motor force than previously available with the standard high temp Neo, you can gain 10-20% more Gauss without having to go to a simply massive motor.

Black NEO option

From setting world records or just crushing souls with insane output and bottom end performance adding the Fi Car Audio Black Neo to your next subs will up your game for sure
