Fi Car Audio manufactures handcrafted subwoofers that are proudly designed and built in Las Vegas. The subwoofers are made from USA made steel and manufactured in-house. .

Fi Car Audio has completely switched its subwoofer portfolio to neodymium subwoofers from 2021.

For each subwoofer you have the choice from a variety of Upgrade options:

• With the NEO 3.X and NEO 4.X series you can choose between the different sizes of neodymium Motor Designs and number of neodymium cores .
• The NEO 3.X series is available in subwoofer dimensions of 12", 15" and 18".
• With the NEO 4.X series you can choose from 12", 15", 18" and gigantic 21" subwoofers.
• There is also the possibility of additional centering spiders to use.
• Both series are available with either D1 or D2 voice coils available.
• In addition, Fi Car Audio offers the option of one of 3 cooling designs where we will automatically select the most efficient option for you.
• The Dustcap is always made of carbon. Here you can choose from glossy carbon in 6" or 7", or a woven dustcap carbon design in 6"
• Finally, you have the opportunity to color of the Fi Car Audio logo to choose from. Almost all RAL colors are available here. White is defined as standard. If you want a specific color, write to us!

Information about all Fi Car Audio Neo3.X subwoofer models:

• New cooling and inductance features built in stages. The first stage is a machined aluminum pole sleeve. This provides better heat dissipation and is the first part of the inductance linearization and reduction. The second stage is a combination of the pole sleeve and a domed aluminum compression cap. This increases the compression ratio for cooling and reduces the inductance in the swing. The third stage uses the pole sleeve, compression cap and a thick aluminum fin, which again lowers and linearizes the inductance and aids heat dissipation. With the third stage we have reduced the inductance by almost a factor of 3 because we don't use aluminum.

• All cables are sewn in the same pattern and use the screwed terminal block, as well as the original hybrid design. But we have added push terminals that use the same setup, with the ability to handle much larger speaker cables and completely remove the multiple soldering and crimping points that could create unwanted resistance.

• All Neo3.X subs use the high Xmax dual 1 ohm and dual 2 ohm coils for 34mm disposable Xmax.

Classification of the Fi Car Audio Neo3.5 subwoofer:

• Comparable to the older Q-series drivers. Great SQ (especially with full Cool/IND options. 2 spiders standard but can be upgraded to 3. 1750W. Works in sealed, ported, 4th and 6th order enclosures. For SQ-oriented everyday applications. 12″, 15″, and 18″ sizes.

classification of Fi Car Audio Neo3.7 Subwoofer:

• Comparable to older BTL series drivers. Great, robust driver for everyday use with great heritage. Comes standard with 3 spiders but can be made with 4 or 5 if required for increased mechanical durability or SPL specific applications. 2500W power handling. Works well in ported or 6th order enclosures.Available in 12″, 15″, and 18″ sizes.

classification of Fi Car Audio Neo3.9 Subwoofer:

• Comparable to the Team3 series. High motor power and extreme attack. Great for SPL or high pressure applications. 2500W+. Comes standard with 4 spiders, but can be equipped with 5 or 6 spiders if required for SPL specific applications. Works great in high pressure bass reflex or 6th order bandpass enclosures. Available in 12″, 15″, and 18″ sizes.

This provides better heat dissipation and is the first part of the inductance linearization and reduction. The second stage is a combination of the pole sleeve and a domed aluminum compression cap. This increases the compression ratio for cooling and reduces inductance in the drive range. The third stage uses the pole sleeve, compression cap and a thick aluminum fin, which in turn lowers and linearizes the inductance and helps with heat dissipation. With the third stage we have reduced the inductance by almost a factor of 3 when not using aluminum.

• All cables are sewn in the same pattern and use the screw-down terminal block as the original hybrid design. But we've added push terminals that use the same setup, with the ability to handle much larger wires and completely remove the multiple soldering and crimping points that could introduce unwanted resistance.

classification of Fi Car Audio Neo4.7 Subwoofer:

• Comparable to SP4 and BTL4 series chassis. Solid 4" workhorses that work well in just about any application. Standard 3 spider suspension. Power handling of 3500W. 12", 15", and 18" sizes.

classification of Fi Car Audio Neo4.9 Subwoofer:

• Comparable to SP4+ or Team Series drivers, depending on coil option. Comes with standard 4″ and 4 centering spiders, with the option for the Plus 4″ coils, with extra centering spiders and gap option. 4 centering spiders to standard and 5 centering spiders on Team coil. Works well in ported, 4th or 6th order bandpass enclosures. Power handling 3500W-4500W depending on coil and Cool/IND options. Available in 12″, 15″, 18″ and 21″ sizes.

classification of Fi Car Audio Neo4.11 Subwoofer:

• The middle between the Delta and Omega lines: Comes with standard 4″ coils and 4 centering spiders with the options on the Plus 4″ Wash , extra centering spider and gap option. Designed for modern monster applications in ported, 4th or 6th order bandpass enclosures. Buildability: 3500 watts depending on coil and cool/IND options. Available in 12″, 15″, 18″ and 21″ sizes.
