Fi Car Audio HC Series Subwoofers

The New HC Series of subwoofers offering ultra low sub bass response to tight, controlled and powerful attack. For one brutal daily driver sub
The HC Series signals a return to traditional ferrite motors. The HC Series is the latest in the progression of Fi subwoofers geared towards thundering daily drivers. Utilizing a favorite 3 stack ferrite magnet design using US steel cut on our water jet and finish machined on our CNCs, there is plenty of motor force in the FEA derived design for both daily and SPL use. Utilizing a solid pole and staged aluminum cooling helps keeps thermal temperatures under control. A classic 3 stack of ferrite magnets provide the Gauss while 4 Fi designed 10″ heavy progressive spiders keep things under mechanical control. Utilizing a special 144 tinsel count leadwire that is double sewn to the spider pack, there are no losses in power transfer to the coil (available in either standard stitched with terminals or the hybrid stitched with bolted termination.
The HC brings back an updated favorite with the performance you have come to expect from our classic ferrite designs.
NEW PLUS Feature adds extra motor slug, lowers Fs and has compliant spider pack.

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 10-30 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.If we sent you a faulty subwoofer, or was received damaged, you will still be liable for a 30% refund fee plus all applicable return shipping costs.
By reading these terms and conditions, you agree to wait for the item to be recieved. If order is delayed or if there are manufacturing delay or part shortage you will be notified in good time.
If you have anymore questions do not hesitate in contacting us.
