Important Owner Information
Read and Follow Instructions –Please read this entire manual before unpacking and setting up your Radia Freestanding loudspeakers. For maximum performance and years of trouble-free enjoyment, all operating and care instructions should be followed.
Retain – DO NOT discard any factory packing material. The packing and shipping materials may be required in the unlikely event your loudspeakers need to be moved or shipped to our service center at BG.
Cleaning – Use a wax-free cleaning substance only (i.e. Pledge™) with a soft, dry polishing cloth, not a paper-based chamois. DO NOT apply any cleaning solutions to the grill cloth.
Liquid – DO NOT place BG loudspeakers near an open source of liquid that may spill on the loudspeaker surfaces.
Heat – DO NOT place BG loudspeakers near a direct heat source.
Tipping – BG loudspeakers should be placed on a smooth flat surface utilizing the enclosed spiked feet in order to ensure that the loudspeaker(s) do not tip over. A loudspeaker tipping over can pose a hazard for small children and pets.

General Information
Unpacking Your BG Loudspeakers
1.Lay the shipping box down on the floor, ensuring that you have adequate space to lay the loudspeaker down after removing it from the shipping box. Note: If your floor is not carpeted, lay a blanket or other suitable soft fabric on the floor to prevent damage to your loudspeakers.
2.Rotate the box so that the white product label affixed at the factory is on top and facing up.
3.Pull the top flaps of the shipping box up, taking care not to cut yourself on the staples used to close the box. Open the other cardboard flaps to expose the loudspeaker still cradled in it’s protective foam and inside a protective plastic bag. Remove the foam pieces over the top of the speaker. DO NOT open box ends.
4.Remove the loudspeaker by lifting it straight up and out of the box. Due to their weight, we recommend that two people work together to remove Models 520i and 420i.
Assembly Instructions: Special assembly instructions can be found in the last section of this manual.
Proper Hookup: Red terminal post to positive (+) amplifier post Black terminal post to negative (-) amplifier post
Most BG loudspeakers can be bi-wired or bi-amped by simply removing the gold plated jumper to allow separate wires to be run to the low and high pass section of your system.
Break-In Times: Typically a BG loudspeaker requires not less than 48 hours of operation at moderate sound level before reaching its optimum sound quality. This improvement may be rather subtle but noticeable for a trained listener.
Note: Do not play your loudspeakers excessively loud to try to accelerate this process!
Amplifier: BG loudspeakers are extremely accurate and deliver a high degree of detail and resolution. Therefore a good 100-150 watt per channel amplifier or receiver will deliver adequate power for typical system and room size. Your authorized BG dealer can recommend an amplifier best suited to your needs.

Home Theater and Stereo Applications
Refer to the diagram on page 7 that depicts a recommended layout for Radia loudspeakers. This diagram is an overhead view of a typical listening room with the video screen located at the top of the diagram (the front of the room). Keep in mind the room is a part of the sound reproduction system and has a significanteffectonthesoundyouexperience,especiallyatlowerfrequencies (see subwoofer setup on page 9).
Locating a loudspeaker close to the wall increases bass output. It may also increase the boominess of the bass and can artificially alter the loudspeaker’s tonal balance. We recommend that you spend some time adjusting the position of the loudspeakers, moving them in and out gradually, to get the sound you prefer. You may toe the loudspeakers in or out (rotate them around their vertical axis towards or away from your listening position) to improve high frequency balance (as indicated by the dashed lines on the diagram). In general, best results are obtained when the front left and right loudspeakers have their axis intersecting slightly behind the position of the listener.
The relative location of your listening position to the loudspeakers is important as well. If possible, do not select a listening position less than three feet (one meter) from the rear wall of the room. As with adjusting the placement of your loudspeakers, you can also adjust your listening position to get the most desirable bass reproduction and high frequency resolution.
The Radia 520i and 420i loudspeakers are dipole devices, which simply means that sound comes out of the rear of the loudspeaker as well as the front. For optimum performance they should not be installed inside a cabinet or alcove.

Home Theater Applications
If you plan to use your BG loudspeakers for home theater or multi-channel audio, here are some additional recommendations.
1.The center channel loudspeaker should be positioned on top of your television or a shelf directly above or below it. NOTE: The Radia 220i center channel loudspeaker is magnetically shielded.
2.If you are using a projector, you will need a suitable stand to position the center channel loudspeaker on the floor in front of the screen or a bracket above or below the screen. Aim the loudspeaker so it is pointed at your listening position. The center channel loudspeaker should be as close as possible to the screen so the voice soundtrack appears to come from the video image.
The optimum position for all five loudspeakers requires the same distance from the listening position (i.e. distance A, B and D are equal), see diagram on opposite page. If it is not possible to get the distances equal, you can use the delay and level adjustment functions available in most home theater processors to compensate for the differences in distances.
The diagram shows the optimum placement for the rear loudspeakers. The subwoofer should be placed beside or behind either the left or right front loudspeaker. For multiple subwoofers see your authorized BG dealer for advanced setup procedures.
This manual addresses 5.1 surround sound systems. Where 7.1 or higher systems are being utilized see your authorized BG dealer for advanced setup procedures.
