PRACTICE SAFE SOUND

Continuous exposure to sound pressure levels over 100dB may cause

permanent hearing loss. High powered auto sound systems may

produce sound pressure levels well over 130dB. Use common sense

and practice safe sound.

PRATIQUEZ UNE ÉCOUTE SANS RISQUES

Une exposition continue à des niveaux de pression acoustique upérieurs à

100 dB peut causer une perte d’acuité auditive permanente. Les systèmes

audio de forte puissance pour auto peuvent produire des niveaux de

pression acoustique bien au-delà de 130 dB. Faites preuve de bon sens et

pratiquez une écoute sans risques

PRACTIQUE EL SONIDO SEGURO

El contacto continuo con niveles de presión de sonido superiores a 100

dB puede causar la pérdida permanente de la audición. Los sistemas de

sonido de alta potencia para automóviles pueden producir niveles de

presión de sonido superiores a los 130 dB. Aplique el sentido común y

practique el sonido seguro.

PRAKTIZIEREN SIE SICHEREN SOUND

Fortgesetzte Geräuschdruckpegel von über 100 dB können beim

Recommended Enclosures

This manual outlines two speciﬁc types of enclosures that provide distinctly dif-

ferent performance. This section is to help you decide which type is best for your

application.

Sealed Enclosures

Sealed enclosures are the simplest to build. The most important part of building

a sealed enclosure is to make sure that the enclosure is airtight. Using glue and

some type of sealant on all seams will ensure solid construction and prevent air

leaks. The box volume will directly impact the performance of the speaker. Larger

enclosures will provide ﬂatter response and deeper bass where smaller boxes will

provide a bump in the response curve and generally higher output for greater SPL.

Advantages of sealed enclosures:

• Small enclosures

• Linear (Flat) response

• No port noise

• High power handling at all frequencies

• Excellent for sound quality

• Extended low frequency output when compared to vented enclosures

Vented Enclosures

Vented enclosures vary only from the sealed enclosure in that a vent or port is

added to “tune” the enclosure. The enclosures recommended are designed for

great overall performance. Larger boxes tend to be easy to tune to lower frequen-

cies while medium and small boxes are easier to tune to higher frequencies. The

vented design is less linear in response than the sealed box but with noticeably

more output at the tuning frequency.

Advantages of vented enclosures:

• Higher average output than sealed

• Tuning frequency can be easily adjusted by changing port length

• Deep bass response with lower power requirements

• Great for high output with limited power

Inﬁnite Bafﬂe Design

These designs typically called “IB”, are the easiest enclosure types to build. The

reason is that you are not actually building an enclosure, but rather simulating one.

This is done by closing off a cavity area (ie; car trunk, enclosed area of a boat hull)

with a bafﬂe board. This creates your “IB” sub-woofer system. Essentially, an “IB”

design can just be considered a large sealed enclosure design. Given that an “IB”

design does not rely on a volume of air for its suspension, the low frequency output

is driven by the speaker’s inherent damping or “Qtc”.

Advantages of inﬁnite bafﬂe design:

• Easy to build

• Light-weight

• Deep bass response with lower power requirements

Vented vs Sealed vs Inﬁnite Bafﬂe

The graph shown here is a sample of how SPL and Excursion differs between the

various enclosures.

Building an Enclosure

To work properly, the walls of the enclosure must be rigid and not ﬂex when sub-

jected to the high pressures generated by the speaker’s operation. For optimum

performance, we recommend using 3/4” MDF (Medium Density Fiberboard) and

internal bracing. The enclosure should be glued together and secured with nails

or screws.

Calculating Volume

Calculating volume is merely a matter of measuring the dimensions in inches and

using the formula: H x W x D divided by 1728 (cubic feet). See block below.

Box Volume Height” x Width” x Depth”

Divided by (cubic feet) 1728

If two facing sides are of uneven length, add them together and divide by two to

take the average. Using this number will give you the volume without the necessity

of calculating the box in sections and adding the sections together. The thickness

of the bafﬂe material reduces the internal volume so this must be subtracted from

the outside dimensions to determine the internal volume. The speaker itself also

reduces the internal volume. The amount of air displaced by each model is listed

on the speciﬁcation sheet and should also be subtracted from the gross volume

calculation.

Sealed Enclosure

NOTE: Vb is the internal volume, before any speaker and/or port dis-

placement is added. All external dimensions were based on the use of

3/4” (1.90cm) materials.

NOTE: When using enclosures other than recommended, call Technical Support

for correct application.
