power supply "rail" voltages needed for peak outputs. With a Class H
design the rail voltages are not constant. They swing high when the
music demands it and stay low during quiet passages. This is achieved
by a sophisticated high frequency switching power supply. Power
dissipated as heat is greatly reduced and more power is available per
dollar of cost. A second benefit is that they tend to have high peak
power relative to their steady state power. The SubSeries 500, for
example, has 500 watts continuous power and is capable of over 1500
watt peaks. The result is a subwoofer capable of the great transients
required by dynamic music and explosive sound effects. The SubSeries
500 offers the latest most efficient implementation of this special Class H
technology.
The SubSeries 500 cabinet is constructed from thick MDF and aluminum
extrusions. These materials and their application in this design form an
extremely rigid cabinet free of any audible resonances due to panel or
brace movement. Large curvilinear ports with large radius flanges
drastically reduce port noise to inaudible levels while minimizing acoustic
compression common to smaller diameter port designs. Air will create
noise whenever it comes into contact with a hard surface. Minimizing the
area of the surface that the air actually comes in contact with reduces
this noise.
A severe duty aluminum cast basket, very large magnet structure, and a
high power voice coil allow the SubSeries 500 to effortlessly churn out
low frequencies at foundation shaking levels.
III. Warranty Registration
We recommend you take a few moments now to register your warranty
on-line at www.psbspeakers.com so that we will be able to serve you
better in the future.
Unpacking
The packing materials are designed to protect your subwoofer from
damage during shipping. Retain the packaging in case the need arises to
transport the speaker in the future.
IV. Cabinet Care
Cabinets have varying materials and finishes, including wood veneers
and painted cast anodized aluminum parts. They should be treated as
you would any fine furniture with similar finishes. Dust lightly with a soft
cloth; avoiding abrasives. If necessary, wipe carefully with a cloth slightly
dampened with glass cleaner to remove heavy soil.
Grille
A lint brush does a good job of cleaning grilles. Grilles can be taken off
and vacuumed if you prefer. Avoid touching speaker diaphragms.
