Introduction

Thank you for purchasing a Sunfi re Dynamic 

Series Subwoofer. We hope you enjoy it and 

the music it makes as much as we have en-

joyed creating it for you.

The big features of the subwoofer are its 

high-effi ciency Class D digital amplifi er, and 

its computer-optimized woofer and passive 

radiator design. And, the Sunfire Dynamic 

Series' extended frequency response means 

that your 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.

Quick Start Guide 913-164-00 Rev A

Location

Your SDS Subwoofer is designed to be placed 

in a corner for optimum performance.   

Ex per i ment with at least two corners and de-

cide which sounds the best. 

Although low frequencies are non-di rec tion al, 

room re fl ec tions, standing waves, resonance 

and ab sorp tion strongly affect the per for mance. 

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 mag net ic tapes 

and discs. This will reduce the chance of the 

magnetic fi elds upsetting the CRT screen or 

erasing your magnetic media.

Also position the control panel so that it is 

not touching anything and can receive good 

ventilation. 

Using Two Subwoofers

With two subwoofers, the sound output will 

double. Place each subwoofer in a corner, and 

ex per i ment with the location and phase control 

to achieve the best bass response.

1.  Read these in struc tions.
2.  Keep these instructions.
3.  Heed all warnings.
4.  Follow all instructions. 
5.  Do not use this apparatus near water.
6.  Clean only with dry cloth.
7.  Do not block any ventilation openings. Install 

in accordance with the manufacturer’s in-

structions.

8.  Do not install near any heat sources such 

as radiators, heat registers, stoves or other 

apparatus (including amplifi ers) that produce 

heat.

9.  Do not defeat the safety purpose of the polar-

ized or grounding type plug. A polarized plug 

has two blades with one wider than the other. 

A grounding type plug has two blades and a 

third grounding prong. The wide blade or the 

third prong are provided for your safety. If the 

provided plug does not fi t into your outlet, 

consult an electrician for replacement of the 

obsolete outlet.

10. Protect the power cord from being walked on 

or pinched, particularly at plugs, convenience 

receptacles, and the point where they exit 

from the apparatus.

11. Only use attachments/accessories specifi ed 

by the manufacturer.
