NCLOSURES

A vented enclosure acts like a sealed 
enclosure at frequencies above its tuned 
(resonance) frequency. At resonance 
(which is defined by the vent), the vent 
produces the majority of sound – the 
subwoofer cone is nearly stationary while 
the air inside the vent vibrates. This 
provides greater mechanical power 
handling at and above resonance, but 
reduced mechanical power handling below 
resonance. Since the subwoofer cone and 
voice coil don’t move much at resonance, 
airflow across the voice coil is minimized 
and thermal power handling is reduced 
slightly at resonance.

Vented enclosures provide better 
efficiency in the 40Hz – 60Hz range, at 
the expense of sound output in the lowest 
octave (below 40Hz). The use of an 
infrasonic filter is recommended with 
vented enclosures. An optimum vented 
enclosure for a Club Series subwoofer is 
larger than an optimum sealed enclosure.

See accompanying data sheet for specific 
enclosure dimension requirements.

DVANTAGES

• An optimum vented enclosure has 

greater efficiency and higher output in 
the 40Hz – 60Hz range than an optimum 
sealed enclosure.

• An optimum vented enclosure provides a 

greater sensation of bass than an 
optimum sealed enclosure.

• A Club WS1000 or WS1200 subwoofer in 

an optimum vented enclosure will 
require less amplifier power to achieve 
a given acoustic output (down to the 
enclosure’s resonance frequency) than 
in an optimum sealed enclosure.

NCLOSURES

Band-pass enclosures can provide the 
most output from any amplifier and 
subwoofer combination over a limited 
band of frequencies, but that additional 
output comes at the expense of sonic 
accuracy. Band-pass enclosures combine 
a sealed or vented enclosure that houses 
the subwoofer along with a vented 
chamber into which the subwoofer 
outputs its sound. The vented chamber 
acts as an acoustic low-pass filter which 
attenuates high frequencies in the 
subwoofer’s output. That attenuation of 
high frequencies can make it very 
difficult to hear amplifier and speaker 
distortion; consequently, you may not be 
able to determine when the subwoofer is 
in danger of being damaged.

See accompanying data sheet for specific
enclosure dimension requirements.

• An optimum band-pass enclosure has a

ONSTRUCTION

Band-pass-enclosure construction is more 
difficult than vented-box construction 
and, as with vented enclosures, the 
design parameters for the vented section 
must be followed carefully. (The sealed 
section is more forgiving of small design 
and construction variations.) Fortunately, 
there are many prefabricated band-pass 
enclosures that are designed to extract 
the most output possible from nearly any 
subwoofer. Prefabricated band-pass 
enclosures are strongly recommended if 
you must have a band-pass enclosure. If 
you choose to build your own band-pass 
enclosure, use medium-density fiberboard 
(MDF), glue and screws to construct the 
enclosure,and be sure to seal all joints 
with silicone caulk.

ECOMMENDATION

Band-pass enclosures are recommended 
only for enthusiasts who want high 
sound-pressure levels (SPL) without 
regard for sonic accuracy. If high SPL 
AND great-sounding bass are your goals, 
choosing a vented enclosure is 
recommended instead.

NCLOSURE PERFORMANCE 

TRADE-OFFS

• Reduced output in the lowest octave 

(below 40Hz).

• Reduced mechanical power handling 

below the enclosure’s resonance 
frequency. The use of an electronic 
infrasonic filter is strongly recommend-
ed, to reduce the chance of overdriving 
the subwoofer below the enclosure’s 
resonance frequency.

• An optimum vented enclosure will 

always be larger than an optimum 
sealed enclosure.

ONSTRUCTION

Vented-enclosure construction is more 
difficult than the construction of a sealed
enclosure. The enclosure volume and port
dimensions have a specific relationship 
with the physical and electromechanical
characteristics of the subwoofer, 
requiring that the recommended 
enclosure volume and port characteris-
tics be strictly observed. As with sealed 
enclosures, use medium-density 
fiberboard (MDF), glue and screws to 
construct the enclosure, and seal all 
joints with silicone caulk.

ECOMMENDATION

Club WS1000 and WS1200 subwoofers in 
vented enclosures are recommended for 
enthusiasts who prefer accentuated bass 
response, for those who have plenty of 
cargo space to devote to a subwoofer 
enclosure and for those who will use a 
less powerful amplifier to drive their 
subwoofer. The volume and port 
dimensions indicated on the included 
technical data sheet must be followed 
precisely to ensure optimum 
performance.
