All NEO 3.X Series

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 extrusion 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 Neo3.X subs use the high Xmax dual 1 Ohm and dual 2 Ohm coils for 34mm 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.

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

Description
The Bass Blaster subwoofer series is a truly unique blend of car audio nostalgia and modern technology. Designed and built as a product of love for car audio, this subwoofer will look as good in your installation as it will sound. As lifelong enthusiasts ourselves, we knew the demands this subwoofer would need to meet. The engineering expertise of Jacob Fuller, founder of Sundown Audio, has led to a subwoofer that can take the abuse of high-powered systems that the modern-day enthusiast likes to throw at everything. Advanced cooling techniques, high-excursion linear suspension, and classically inspired aesthetics mean The Bass Blaster will give you the best-sounding bass, for a long time, as you turn the heads of anyone that takes a look.

Design
Our philosophy with The Bass Blaster was to recreate the feel of car audio from our youth. The blue surround is not just our branding color, it is an homage to woofers of the 1990s that used brightly colored surrounds as a signature look. The balance of the blue to the grey/silver basket and cone harkens back to the early 2000s when some of our favorite woofer models sported a distinct style. The aluminum dust cap gives depth and texture to the woofer as a whole and adds rigid reinforcement to the cone body. The genesis of the design was the motor itself, the large vent for the four-inch coil caught our eye in car audio shops in the 1990s. Jacob Fuller captured that look while tapering the vent and adding a pole cap so as to not compromise modern cooling techniques for the best performance-to-aesthetics ratio possible. Topped off with the metal mesh over the magnet slugs, The Bass Blaster is the 90s/2000s woofer we all wish we had in our teens, but even better that we have it in our 40s.
