INSTALLATION PROCEDURE

The diagram above shows the typical

installation procedure into a fiberglass panel using

the supplied hardware. Always follow proper

safety procedures when working on a vessel.

Before cutting, drilling or inserting any screw, check

clearances on both sides of the planned mounting

surface. Also check for any potential obstacles, such

as wiring harnesses, fuel lines, hydraulic lines, etc.

Use

eye-protection at all times and a dust mask and

gloves when cutting.

1) Choose a f lat mounting sur face that has

sufficient

depth and air space behind it to accept

the subwoofer.

2) Cut a 8.875-inch (225 mm) diameter hole.

3) Run the speaker cable to the mounting location.

4) Place the woofer in the hole and mark the screw

hole locations using a sharp, pointed tool.

5) Remove the woofer and drill a pilot hole

(see chart on next page) in each of the screw

locations. It is also advisable to use a hand-driven

countersink tool on each hole to further inhibit

gel-coat cracking of fiberglass panels.

6) Connect the speaker wires and place the woofer,

with its grille in place, into the opening

7) While holding the speaker firmly in its mounting

location, evenly snug the mounting screws in a

criss-cross pattern, then hand tighten in a criss-

cross pattern.

Total Speaker “Q” (Qts): 0.754

Equivalent Compliance (Vas): 1.29 ft3 / 36.53 litres

One-way, Linear Excursion (Xmax)*: 0.42 in. / 10.7 mm

Non-standard installations may require different

hardware. Always use marine-grade, stainless-steel

fasteners to ensure a secure, reliable installation.

Efficiency (1W/1m)**: 87.23 dB SPL

Effective Piston Area (Sd): 50.68 in² / 0.0327 m²

DC Resistance (Re): 3.957 ohm

Nominal Impedance: 4 ohm

Infinite Baffle Use: Yes

Enclosure Use: Yes (Sealed Only)

Power Handling (continuous): 175W

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used

as a comparison to other subwoofers to determine which one is “louder” !

We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and amplifiers.
We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely
affect performance.

SUBWOOFER INSTALLATION DIAGRAM

!!

While this speaker is designed to be water and

spray resistant, it is not designed to be submerged

or to withstand high-pressure water spray.

Please exercise care when washing your boat to

avoid damaging your speaker. Do not install on

submersibles, personal watercraft or any other

vessel likely to be under water at any time.

Prolonged exposure to sound pressure levels in

excess of 100dB can cause permanent hearing loss.

This high-performance speaker can exceed this

level. Please exercise restraint in its operation in

order to preserve your ability to enjoy its fidelity.

When installing a subwoofer in your vessel, it is

extremely important to secure it firmly. This applies

not only to the woofer itself, but also the structure

it is mounted to. If not firmly attached, the speaker

can become a dangerous projectile in a collision.

Please review the mounting information carefully

and use the supplied marine-grade hardware to

mount this product.

recommended for use in Ported Enclosures.

The enclosure recommendations listed are external dimensions which assume the use of 3/4” (19mm) thick material. If you are using 5/8” (16mm) thick material, subtract 1/4”
(6.5mm) from each dimension. Do not use any material with a thickness of less than 5/8” (16mm) as this may compromise the rigidity of the enclosure.

All enclosure volumes listed are net internal volumes! Box volume displacement, port displacement and brace displacement must be added to obtain the final gross internal
volume. All enclosure dimensions listed have already taken this into account.

RECOMMENDED CONTINUOUS RMS POWER RANGE FOR ONE SUBWOOFER DRIVER:

MEDIU M GRAY MINI MUM:

From a r eliabil ity sta ndpoint , th is z one
represe nts a very comfor table operating power
range f or each dri ver. This level of power wi ll not
stress th e w oofer but will not e xtract all of its
perfo rmance potenti al, either.

Use of l ess tha n the minimu m power level
will not dam age the woofer, but may re sult in
unsatis factory pe rformance.

When designing systems with our drivers, it is very important to achieve a good power match between the subwoofer amplifier and the subwoofer driver's capabilities. The power levels listed in the above
chart represent continuous (RMS) amplifier power per woofer and assume that the user will regularly make full use of that power without drastically overdriving the amplifier(s). Make sure you factor system
impedance and the total number of subwoofers into your calculations. Adhering to these power recommendations will result in systems that are both reliable and enjoyable.

LIGHT GRAY OPTIMU M:

This zone rep resents the best compromise
between long-term reliability, high-output and
low-distortion performance. This power level is
lower than the woofer’s continuous power rating
(as published in its s pecificat ions), bu t you will still
be taking advantage of the woofer’s, low-distortion
performance range without undue risk of failure.

DARK G RAY MAXIMUM:

Slightly more SPL will be gained by pushing the
power into this zone, but typically not more than
2dB, compared to the light gray zone. The subwo ofer
driver is designed to operate safely up to this power
range, but not beyond. Operate with caution.

BLACK WA RRANTY VOID:

We do not recomme nd operating woofe rs at
this level of power. In this z one, there is a ver y
high proba bility that the driv er will fail due to
excessive heat and/or mec hanical stres s.

Subwoofer drivers operated at these levels of
power are NOT covered under warranty.
