SUBWOOFER FEATURES

FUSION subwoofers are low frequency drivers capable of delivering extremely high bass levels

from small enclosures. In order to achieve the maximum performance from your new FUSION

Subwoofer, please use one of the recommended size enclosures that best suits your application.

Sealed and vented enclosure sizes can be found in this manual.

BASKET

NV Series Subwoofers feature a uniquely high pressure cast aluminium basket. Development

of the NV Series basket allows rigidity and style for any custom install. Finished in a protective

metal silver paint and detailed with FUSION green enhancements, the basket displays impressive

strength and style.

CONE ASSEMBLY

Development of the high performance pressed paper cone, creates a dynamic low bass

response and high power performance. The cone is ﬁnished in a dynamic silver with NV Series

super graphic, catering for style, strength and sound performance.

SPIDER

In order to keep the cone assembly balanced and linear, FUSION has used green poly cotton ﬂat

spiders to reduce the mechanical distortion for better sound quality.

VOICE COIL

NV Series Subwoofers use dual 2 ohm conﬁguration. This allows a multitude of wiring

combinations for your ampliﬁer system (please see wiring conﬁgurations in this manual). NV

Series Subwoofers utilise high temperature, multi wound black aluminium voice coils.

EXTENDED POLE PIECE

Recognising that an increased linear magnetic ﬁeld for the subwoofer encourages a better low

frequency response, FUSION has extended the internal pole piece to achieve this. The extended

pole piece also decreases distortion.

MOTOR STRUCTURE

The motor structure is constructed from the highest strontium magnetic material triple stacked

and capped with a diamond cut FUSION back plate, has enabled increased power handling and

larger excursion. With the additional venting holes we assure consistent booming.

ENCLOSURES

All enclosures include port and subwoofer displacement. All ports are circle aero ports unless

otherwise stated.

Ported Enclosures: A ported enclosure is generally larger than a sealed enclosure

Sealed Enclosures: A sealed enclosure will be the smallest enclosure you can build. It will have a

tight low frequency response, but not as low as a ported enclosure.

ENCLOSURE CONSTRUCTION

All enclosures should be constructed from 18mm (3/4”) Medium Density Fibre board.

Enclosures should be glued and screwed, because MDF is porous. FUSION recommends

sealing the internal sides with a polyurethane sealer prior to installation. To accurately cut the

subwoofer hole use the unique FUSION ruler guide included inside the FUSION Subwoofer

packaging.

ENCLOSURE PLACEMENT

An important factor is to place the subwoofer enclosure as far back in the vehicle as possible,

so that the natural bass gain of the vehicle is utilised. If your vehicle is a hatch back, always

experiment with which direction the subwoofer is facing. Facing the subwoofer towards the

rear of the car, should enhance the low down bass that NV Series Subwoofers are designed

to produce.

ENCLOSURE TUNING

When tuning the system it is always a good idea to try running the subwoofer out of phase

(which means switching the speaker wires around) with your other speakers. Do this and listen

to the system to see if the perception of bass is more from the subwoofer location or the front

speaker location. Which ever way gives the better perception that the bass is coming from the

front speakers, would quite safely guarantee the subwoofer is wired correctly.

CALCULATING ENCLOSURE ‘BOX’ VOLUME

Cuft:

To calculate Cuft multiply the height (A), width (B), depth (C) in inches, then divide that number

by 1728.

Example: 10" high x 18" wide x 12" deep = 2160 inches³

Divide 2160/1728 = 1.25 ft³

Litres:

To calculate Litres, multiply the height (A), width (B), depth (C) in centimetres, then divide that

number by 1000.

Example: 25.4cm high x 45.72cm wide x 30.48cm deep = 3539cm³

Divide 35396/1000 = 35.39 litres
