Fi Car Audio NEO 3.x Series Subwoofer

Neo3.5:
Comparable to the older Q series drivers. Great SQ (especially with full cool/IND options. standard 2 spider, but can be made with 3. 1750W. Works in sealed, ported, 4th and 6th order SQ oriented daily applications. 12″, 15″, and 18″ sizes.

Neo3.7:
Comparable to older BTL series drivers. Great tough daily driver with plenty of heritage. Standard 3 spider but can be made with 4 or 5 if needed for increased mechanical durability or SPL specific applications. 2500W. Works well in ported or 6th order applications as well as some high pressure 4th orders. 12″, 15″, and 18″ sizes.

Neo3.9:
Comparable to the Team3 series. High motor force and plenty of attack. Great for SPL or high pressure applications. 2500W+. Standard 4 spider but can be made with 5 or 6 if needed for SPL specific applications. Works great in high pressure ported or 6th order applications. 12″, 15″, and 18″ sizes.

NEW BLACK NEO Option. Increases gauss by 15-18%
NEW PLUS option. Upgrade any neo subwoofer to a PLUS; Changes include bottomless mechanical structure, low FS softparts / mid 20hz FS, +1″ extended back plate and depth with longer pillars/pole/coolers.

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

Fi Options Explained

This is a complete list of options; not all options are available on all models.
See drop down selections for options available with each speaker model.

Cooling Stage: The new cooling stages are aluminum rings or plugs that aid in cooling and reducing the inductance of a coil (as well as linearizing it to further reduce distortion). The first stage is a machined aluminum sleeve over the pole. This has better thermal conductivity than steel alone does and reduces the effect of the coils inductance increase being an iron core inductor. The second stage includes the first pole sleeve and adds an aluminum pole cap that increases compression and cooling. The third is the first two stages along with the large visible heatsink that surrounds the outside of the coil and transfers heat to the ambient environment as well as greatly reducing the inward inductance of the coil. The overall effect increases cooling/thermal capacity as well as linearizing in vs outward inductance shift reducing distortion ad increasing bandwidth

Cooling: Self explanatory, the cooling channels are machined into the inside of the sub to help cool the coil FAR better. This option is available for subs that do not have staged cooling. While it is not a visible option, it makes a huge difference in long term thermal capacity.

High QTS: This option is for users who intend on using the subwoofer in only a sealed enclosure.

Low QTS: This option is for users who intend on using the subwoofer in only ported enclosures.

Extra Spider: This option adds an additional spider to the spider pack to help with mechanical power handling and keeping the moving assembly under control. It can have small detrimental effects on the sound quality of the sub if the sub is made too stiff (reducing excursion ability and low frequency bandwidth). But in some applications the losses are offset by the ability to use extra power. An extra spider is not a bandaid for improper subsonic filter settings on your amp/DS with respect to the box tuning (should be 2-3 Hz lower than box tuning to avoid mechanical issues when the port unloads).

Internal Lead: This option is for 8 lead per coil, increasing the current flow from coil to terminals. It is sandwiched between the spiders to keep it linear and from flopping around under extreme excursion.

Plus Coil Pack: This option adds an extra spider and the larger/higher power handling Omega/TeamV3 coil. This well bump thermal capacity from 3500W to 4500W or more depending on other options and application. The extra spider helps keep the additional moving mass and power under control while the coil has much higher current carrying capacity over the standard 4″ coils.

Speaker Terminals

We have two terminal options on selected subwoofers.

Our Standard Push terminal using 144 strand count sewn tinsel leads Or our new Hybrid+ lead system with ring terminal attachment for high power systems.

“Fi Terms & Conditions”

These are not mass produced items. Each and every order is built from the ground up. This is not by using pre made parts and bolting/gluing them together, far from. They are machined to exact tolerance for your given application. There is no mass produced magnet sitting on the shelf, your woofer is made for you, when you order. Sure others can produce drivers faster but our manufacturing goes much deeper giving greater control during manufacturing resulting in a ultra high performance regardless of the footprint.

As a result build time is typically 10-14 days. With the distance from USA to the UK this can be anywhere from 14-28 days till you receive your Fi subwoofer.

We can offer a faster service with additional freight charge to express. Typically 7 days. Please contact us about this before ordering.

Refunds, If your custom-built-item has not yet begun to be manufactured you will be charged a 5% processing fee for refunding your payment. If your speaker has begun to be manufactured, or is finished, but has not shipped, you will be charged a 30% refund fee. If the speaker has already shipped, you will be charged the 30% refund fee plus all applicable return shipping costs.

By reading these terms and conditions, you agree to wait upto the allotted 28 day period. If your order exceeds this due to manufacturing delay or part shortage you will be notified in good time.

If you have anymore questions do not hesitate in contacting us.
