passive network with a Þxed crossover frequency of 70 Hz and a 6 dB per octave slope.

We recommend using this high-pass function with main/satellite speakers that are small and not designed to reproduce low frequencies. If your main speakers are capable of operating full range, then you will not need to use the high-pass function.

To use the high-pass outputs, connect the preamp outs on your preamp/ receiver to the subwoofer’s line level in- puts using good quality RCA type patch cords. Then connect a second patch cord from the subwoofer’s outputs to the inputs of your main ampliÞer. This will allow your main speakers to oper- ate at frequencies above 70 Hz and the subwoofer to operate at frequencies below 70 Hz (see page 16).

6. Line Level Inputs

Connect these unbalanced inputs with RCA type patch cords to the line level outputs of your receiver or preamp.

If your preampliÞer or receiver has a single sub/LFE output, connect it to the subwoofer’s left input jack (see page 14). There is no need to use the subwoofer’s right input jack.

If you want to run your main/satellite speakers full range, use a “Y” adapter at the preampliÞer outputs (see page 15). In this way, you can send the preampliÞer’s output signal to your main ampliÞer and to the subwoofer at the same time.

7. Balanced (XLR) Input

Use this balanced input to connect to the balanced line-level output of a Home Theater preampliÞer or other source. Balanced connections offer superior noise cancellation over unbal- anced connections, so if your preamp has an XLR subwoofer output, we recommend using it.

8. Speaker Level Inputs

Under normal conditions, the preferred connection is through the line level inputs. If this is difÞcult or not possible in your system, then you can use the speaker level inputs. Also, if you expe- rience excessive noise or hum with the line level inputs, often a simple change to the speaker level inputs will result in a lower background noise level.

Connect the speaker level inputs to the speaker-level outputs of your ampliÞer or receiver using speaker wire. The binding posts can accept bare wire, banana, dual-banana or spade con- nections.

Your ampliÞer or receiver MUST have common grounded outputs, or it will be damaged if connected to the subwoofer’s speaker level inputs.

9. Line Fuse

The subwoofer is supplied with a con- servative slow-blow type fuse to protect the electronics.

Always unplug the power cord before inspecting or changing the fuse. Never use a fuse with a larg- er current rating than shown on the markings next to the fuseholder.

10. IEC Linecord socket

The subwoofer comes with a detach- able linecord which connects here.

US (120 VAC) MODEL: Connect the linecord to the subwoofer before connecting the other end to an 120 Volt, 60 Hz AC outlet. The outlet must have a circuit rating of 8 amps or more (a typical home circuit is rated at 15 amps).

Never plug the US (120 VAC) Model subwoofer directly into

220-240 Volts AC as this will cause catastrophic circuit failure.

12 specifications

The Sunfire 12 is a state-of-the-art subwoofer designed to deliver unparalleled audio performance for both music lovers and home theater enthusiasts. Known for its deep, powerful bass response, the Sunfire 12 has become a popular choice among audio engineers and consumers alike. This subwoofer embodies a blend of innovative technology and practical design, making it a standout option in the competitive subwoofer market.

One of the hallmark features of the Sunfire 12 is its impressive 12-inch high-excursion driver. This driver is engineered to move more air than typical subwoofers, resulting in profound low-frequency output. The driver is complemented by a unique Dual Voice Coil design, which allows for greater control and improved linearity during operation, ensuring that dynamic audio passages are reproduced with precision.

The subwoofer also incorporates Sunfire’s patented "Tracking Downconverter" technology. This advanced power supply design ensures that the Sunfire 12 can deliver consistent power output, even during the most demanding audio peaks. The result is a dramatic increase in efficiency, which translates to powerful bass without distortion, even at high volumes.

Another notable characteristic of the Sunfire 12 is its compact size. While it delivers deep, resonant bass, the subwoofer's enclosure is significantly smaller than traditional models. This compact design allows for flexible placement in a variety of home environments, making it an ideal choice for those with limited space. The elegant aesthetic of the enclosure ensures that it can blend seamlessly into any room décor.

The Sunfire 12 also features a sophisticated set of adjustable controls. These allow users to fine-tune the subwoofer’s performance to match the acoustics of their space, ensuring optimal sound quality regardless of the room’s dimensions. The built-in crossover and phase control further enhance the ability to integrate the subwoofer with existing sound systems, allowing for a customized listening experience.

With its robust construction and cutting-edge technologies, the Sunfire 12 sets a high standard for compact subwoofers. Whether for music playback or home theater applications, the Sunfire 12 delivers an immersive audio experience, making it a top choice for discerning audiophiles seeking powerful bass without compromise.
