SWR Golight series Owner's Manual page 4

Congratulations on your purchase of an SWR® golight™ bass speaker
enclosure!
The SWR tradition of innovation and excellence began in 1984, when
founder Steve W. Rabe developed an entirely new concept of bass
instrument amplification. Responding to advice and suggestions from top
L.A. recording bassists of the day who wanted their live sound to resemble
what they heard in studio playback monitors, Rabe developed a full-range,
hi-fi bass system that allowed players to dial in any tone they wanted with
the accuracy of a studio mixing console. The "SWR sound" was born.
When the first Goliath™ 4x10 enclosure was introduced in 1987 it was a
radical departure from the norm. Ten-inch drivers were then considered
too small to adequately reproduce bass frequencies, and a tweeter horn
was thought useful only in full-range PA enclosures. This combination
turned out to be exactly what many bassists had been searching for,
and Goliath speakers became a familiar sight on stages and in studios
worldwide. The original Goliath design has become an industry standard
and remains one of the most imitated bass enclosures in history.
Now, in 2009, SWR proudly introduces the golight series of bass
enclosures. These high-quality, lightweight enclosures are the result of a
painstaking process in which every component of our Goliath Series was
IMPORTANT INFORMATION
• ONLY connect one amplifier to your bass speaker enclosure(s).
Two amplifier outputs connected together may damage your
equipment.
• DO NOT connect speakers with a total impedance load below
the minimum rating of your amplifier to prevent damage to your
equipment. See Impedance Guidelines.
• DO NOT connect speakers with a total power handling capacity
that is below the power output rating of your amplifier to prevent
damage to your speakers.
• ALWAYS switch your system power OFF before connecting or
disconnecting speakers.
• ONLY use unshielded speaker cable of 18 gauge or heavier (such
as 16 or 14 gauge) for speaker connections. Shielded instrument
cable may limit the power delivered to your speaker and the cable
may overheat.
• SWR RECOMMENDS removing any casters from bass speaker
enclosures during performance to extend your bass response by
coupling the enclosure more closely to the floor.

evaluated and, whenever possible, a new lightweight high-performance
component was selected for use in the golight enclosures. The
neodymium speakers were developed during the same extensive testing
sessions that produced the Goliath (Series IV) speakers, introduced in
2007, and are specifically voiced to closely match their tone and power
handling. The Okume wood used for the cabinets impressed us as much for
its pleasing tone and durability as for the significant difference in weight.
Even the grilles and handles are crafted from aluminum in order to reduce
weight as much as possible without sacrificing tone or durability.
We are also proud to have worked extensively with Marcus Miller to
develop the first SWR artist model bass speaker enclosure. The Marcus
Miller golight is a unique 'sealed' 4x10 cabinet designed to deliver the
tight, punchy midrange response that Marcus favors. The MM golight
uses specially designed neodymium speakers that are voiced to take
advantage of the unique acoustics of a sealed cabinet, and deliver a crystal
clear Marcus Miller tailored SWR sound.
We're confident that you will enjoy your new golight enclosure for
many years to come, and many thanks for "Stepping up" to SWR.

IMPEDANCE GUIDELINES
Use the impedance ratings on your amplifier and speakers to
determine if a particular combination of speakers is appropriate
for your amplifier. NOTE: All SWR ® bass speaker enclosures (and
most others) are wired in parallel (not in series), therefore, these
Impedance Guidelines apply only to parallel speaker connections.
group, each speaker will receive equal power from your amplifier.
However, if speaker impedances are not the same, speakers with the
lowest impedances will receive the most power. For example, if 4
and 8 speakers are connected in a group, the 4 speaker will draw
double the power and may be louder than the 8 speaker. Take this
into consideration when calculating power handling capacities and
when positioning your bass speaker enclosures.

This Illustration shows the total
impedance loads of various
combinations of speakers connected
in parallel. Ideally, you will want to
connect your amplifier to speakers
with a total impedance load equal
to the minimum impedance rating
of your amplifier. Operating below
the minimum impedance rating can
easily overheat the amplifier and
cause damage. Conversely, operating
above the minimum impedance rating
will reduce the amplifier's maximum
power output capability.
Notice that different combinations of
speaker impedances can equal the
same total impedance load. If speaker
impedances are alll the same in a
