The Entra Series of loudspeakers continues Infinity's longstanding commitment to accurate sound reproduction. Our patented Ceramic Metal Matrix Diaphragm™ (C.M.M.D.) drivers, precision dividing networks, and rigid, well-braced enclosures combine to deliver uncompromised performance in any stereo or multichannel home-theater system. In addition, Entra Series speakers are magnetically shielded for safe placement adjacent to a television.
UNPACKING THE SPEAKERS
If you suspect damage from transit, report it immediately to your dealer. Keep the shipping carton and packing materials for future use.
PLACEMENT
Stereo
Before deciding where to place your Entra speakers, survey your room and think about placement, keeping the following points in mind, using Figure 1 as a guide:
- For best results, place the speakers 6'–8' apart.
- Position each speaker so that the tweeter is approximately at ear level.
- Generally, bass output will increase as the speaker is moved closer to a wall or corner.
- Refer to "Home Theater" below if you also plan to use the speakers for home-theater reproduction.
Home Theater
For front-channel use, place one speaker on the left and another on the right along either side of the television monitor. Since the speakers are magnetically shielded, you can place them without worrying about the field distorting the TV picture.
For rear-channel use, place Entra One speakers on bookshelves or stands – or Entra floorstanding speakers on the floor – alongside the listening position. Final placement depends on room acoustics, availability of space and your listening preference (Figure 2).
The center channel speaker should be placed on top of or directly below the television and aimed towards the listening area.
NOTE: An Infinity powered subwoofer will add impact and realism to both music and film soundtracks. Contact your Infinity dealer for recommendations on subwoofer models for your application.

FIGURE 3 – This figure shows an alternate layout, which may be more suitable for some rooms.
INSTALLING SPIKED FEET
Entra Two and Entra Three
Refer to Figure 4 as you perform the following steps:
-
The Entra Two and Entra Three come with the round end of their feet exposed for use on hard-surface floors. To expose the spiked end of the feet, lay each speaker on its side and use the enclosed wrench to unscrew and remove the four feet. Screw the round end of each foot into its hole and hand-tighten a nut onto each foot. Leave a minimum of 5/8" of exposed spike. (On thicker carpets, you can increase the length of exposed spike up to 1-1/8.")
-
Carefully stand each speaker upright to sit on its feet.
-
If needed, adjust the feet so each speaker is level and then tighten each nut with the enclosed wrench.
FIGURE 4 – This cross section shows how to install a foot onto the bottom of an Entra floorstanding speaker.
WIRING THE SYSTEM
IMPORTANT: Make sure all equipment is turned off before making any connections.
For speaker connections, use a minimum #16-gauge speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +).
NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options.
The speakers have coded terminals that accept a variety of wire connectors. The most common connection is shown in Figure 5.
To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 6. Connect the - (black) terminals in a similar way. See the owner's guides that were included with your amplifier, receiver and television to confirm connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to - or - to +) when making connections. Doing so will cause poor imaging and diminished bass response.
FIGURE 5 – This example shows how to connect bare wires to the terminals. Banana plugs may also be inserted directly into the rear of the connector.
FIGURE 6 – Wiring diagram shows polarity connections for one channel of a stereo or home theater system.
FINAL ADJUSTMENTS
Check the speakers for playback first by setting the system volume control to a minimum level, and then by applying power to your audio system. Play a favorite music or video segment and increase the system volume control to a comfortable level.
NOTE: You should hear balanced audio reproduction across the entire frequency spectrum. If not, check all wiring connections or consult the authorized Infinity dealer from whom you purchased the system for more help.
The amount of bass you hear and the stereo-image quality will be affected by a number of different factors, including the room's size and shape, the construction materials used to build the room, the listener's position relative to the speakers, and the position of the speakers in the room.
Listen to a variety of music selections and note the bass level. If there is too much bass, move the speakers away from nearby walls. Conversely, if you place the speakers closer to the walls, there will be more bass output.
Nearby reflecting surfaces can adversely affect stereo-imaging quality. If this happens, try angling the speakers slightly inward toward the listening position until the optimum effect is achieved.
Each Entra Series cabinet has a wood-grain-vinyl finish that does not require any routine maintenance. When needed, use a soft cloth, dampened with water only, to remove any fingerprints or dust.
Clean the grille by gentle vacuuming.
NOTE: Do not use any cleaning products or polishes on the cabinet or grille.
