How to install

Choosing where to place the speaker systems

• Sounds played through speaker systems are easily affected in 

subtle ways by the conditions in the listening space.

• For best sound, choose a solid floor upon which to place the 

speakers, and position the speakers as shown below. The level 

of low sounds can be adjusted by moving the speakers closer 

to or further from the wall. Adjust the speakers so that they are 

equidistant from their respective side walls to assure balanced 

sound.

• Place the left and right speakers equal distances from your 

listening position for good stereo sound. Use speaker cords of 

the same length for each speaker.

• So far as possible, place the front left and front right speakers 

on the same plane as the TV screen.

• To achieve optimum surround sound, you should place the TV 

between the left and right speakers, with the speakers 

pointing at a 50 to 60 degree angle toward the listening 

position.

• If the room has a lot of reverberation, we recommend hanging 

heavy fabric on the walls, and/or putting a carpet on the floor 

to damp the sound. For best results, cover walls completely.

• These speakers are bookshelf-type speakers which will give 

their best performance when placed on a solid, level surface 

off the floor. Placing the speakers directly on the floor will 

result in boomy, undefined sound. Ideally, the tweeters should 

be at about ear level when seated in your listening position. 

We recommend using the CP-31B speaker stand for optimal 

sound and stability. 

If you choose to use the CP-31B speaker stand, make sure 

you secure it with the screws provided. 

(for more details, refer to the operating instructions of 

CP-31B)

• This unit has two screw holes on the bottom panel. These 

holes are meant for joint use with speaker brackets and 

speaker stands; speaker brackets are commercially available 

and can be used to mount the speakers on a wall. The diagram 

below shows the spacing and size of the holes. When 

choosing a speaker bracket, make sure that it can hold at least 

2.5 kg. Please also read the instructions that come with the 

bracket. Speakers that are not mounted properly are a hazard. 

• Pass a commercially-available reinforced string through the 

safety metal to securely support the speaker to the wall. Be 

sure that the wall to which you fasten the speaker is strong 

enough to support the weight of the speaker. After fastening 

the speaker, make sure that it does not fall over.

Mounting the Safety metal for Fall-Prevention

• Do not attach the safety metal directly to the wall. It should 

only be used in conjunction with reinforced string to prevent 

the speaker from falling.

• Using the included screw, tightly secure the safety metal to 

the backside of the speaker. 

• Pass two reinforced strings through the safety metal, and 

fasten the speaker to the wall as shown above.

• If you mount the speakers on the wall or ceiling, first make 

sure that the mounting surface can bear at least 2.5 kg. If 

you’re unsure of the load capability, please seek professional 

advice.

After installing, make sure the speakers are securely fixed.

• Pioneer assumes no liability whatsoever for damages 

resulting from assembly, improper mounting, insufficient 

reinforcement, misuse of the product, acts of nature, etc.
