Proficient Protege F5 Series Owner's Manual page 3

INTRODUCTION
Thank you for purchasing the Proficient Protege FS Series Subwoofer. We hope you enjoy it and the music
it makes as much as we have enjoyed creating it for you. The big features of the subwoofer are its high-
efficiency Class D digital amplifier, and its computer-optimized woofer and passive radiator design. These
powerful forces combine to produce as much bass as several 15-inch drivers mounted in a cabinet the size of
a small refrigerator! In addition, the Proficient Protege Sub's extended frequency response means that your
new Protege subwoofer is the perfect match to virtually any loudspeaker. The result is extraordinarily high
operating efficiency – that is, more acoustic output for each watt of input.
UNPACKING
Your Proficient Protege FS Series Subwoofer should reach you in perfect condition. If you do notice any shipping
damage, please contact your Proficient Authorized Dealer immediately. Gently lift the unit out the box and
remove all the packing material. It is important to save all of the packing materials and the box in case your
subwoofer ever needs to be moved or shipped for repair. Keep your sales receipt as it is the only way to
establish the duration of your Limited Warranty and it may come in useful for insurance purposes. Please
take a moment to read the serial number located on the control panel and record it in this manual.
SUBWOOFER PLACEMENT (See Diagram 1)
Your Proficient Protege FS Series Subwoofer is designed to be placed in a corner for optimum performance.
Experiment with at least two corners and decide which sounds better. Although low frequencies are
non-directional, room reflections, standing waves, resonance and absorption strongly affect performance.
Moving the subwoofer from one corner to another can have a major effect on the bass response. Keep it
at least two or three feet away from any CRT screen, computer, VCR or magnetic tapes and discs. This will
reduce the chance of the magnetic fields upsetting the CRT screen or erasing your magnetic media. Also,
position the control panel so it is not touching anything and can receive good ventilation.
TWO SUBWOOFERS
With two subwoofers, the sound output will double. Place each subwoofer in a corner, and experiment with
the location and phase control to achieve the best bass response.
