INFINITY®REFERENCE ENCLOSURES

Looking for a more moving audio experience? Take Infinity

car audio for a ride. Innovative materials and breakthrough

engineering have always put Infinity products out in front of the

competition. So expect extreme output from these enclosures, but be

prepared for accuracy and detail that may surprise you. Infinity

Reference Series enclosures deliver deep, thunderous bass, free from

distortion and port noise, thanks to the patented Slipstream port.

So what’s the big deal about a

port? The Slipstream port in

Infinity Reference enclosures

eliminates that annoying

“whooshing” or “chuffing”

noise characterizing other

ported enclosures. Port noise

isn’t just nasty-sounding

distortion; it’s a sign that

something is wrong. Ports

make noise when they can’t

transfer enough air or when

the air in the port is moving

so fast that the air outside

the box can’t keep up. When

ports can’t transfer enough

air, the enclosure and the

woofer operate almost like a

sealed box, with increased

driver excursion, less bass

and a greater likelihood that

the woofer will be damaged.

The contours of the Slipstream

port flares are precisely

calculated to minimize

turbulence so there’s

no port noise. Also, the

Slipstream port’s area is

calculated differently than

the area for a conventional,

straight-sided port. As a

result, the Slipstream port

can effectively tune the

enclosure to a lower frequency

than a straight-sided port

can, with an equivalent

cross-section. That means

better woofer reliability and

more low bass from Reference

Series enclosures.

Since 1968, Infinity engineers

have been designing and

constructing enclosures for

award-winning home audio and

home theater speakers and

subwoofers. This expertise,

coupled with extensive

knowledge of in-vehicle

acoustics, has driven the

development of this world-

class line of enclosed

subwoofers. If you are looking

for great bass, free from

noise and distortion, look

no further.
