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.

• 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.

• This speaker is a bookshelf-type speaker which will give best 

performance when placed on a solid, level surface off the floor. 

Placing the speaker directly on the floor will result in boomy, 

undefined sound. 

• Pioneer assumes no liability whatsoever for damages 

resulting from assembly, improper mounting, insufficient 

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

Using the Foam Plug

On the rear side of the unit, a foam plug is provided to allow 

adjustment of the bass sound. The foam plug can be removed if 

desired to produce a different bass emphasis. 

The following can be taken as general guidelines for use of the 

foam plug:

• Mounted in the middle of a rack: Leave the foam plug in place

• Mounted on the top of a rack or on the floor: Remove the foam 

plug

When using the silicon rubber feet

These speaker systems have been provided with silicon rubber 

feet. Use them to adjust the four corners to produce optimum 

stability.

Using the template (see end page) will allow easiest adjustment of 

the setting angle.

Using the template

1

Open the hole in the template along the line indicating 

your desired setting angle.

2

Align the line with the front of the unit, and then align 

the template with the cabinet. 

3

Affix the four silicon rubber feet in alignment with the 

four cut-out holes.

Attaching and Removing the Grille

It is recommended that this speaker system be used with the grille 

net attached, but it can be removed if desired. To remove, follow 

these instructions:

1

To remove the grille, place your fingers at the outside of 

the grille toward the bottom and pull gently outward. Then 

do the same at the top to detach.

2

To reattach the grille, hold the speaker grille with the 

triangular symbol pointing upward, then align the four pins 

on the back side of the grille with the holes in the speaker 

and press in firmly.

Do not force the foam plug into the hole excessively, 

since it might be pressed inside the speaker and be 

impossible to remove.
