Speaker Placement Considerations Achieving the best performance from your AV123 x-series speakers requires several details to follow when setting up your speakers in their new environment. Tips and suggestions for the most desirable placement techniques are listed throughout this section. At the end of this section you will also find more information on placement alternatives in unique situations.
bit of asymmetry here is actually preferable. Symmetrical placement generally results in larger standing waves in the room that reinforce certain frequencies and diminish others. When you take the time to place your speakers properly, you’ll realize better “imaging” (the apparent lateral placement of individual instruments or voices), and more depth or “layering”.
Center Speaker Equally Between Left and Right T LEF CENTER RIGH T speaker), this is especially effective in creating a “phantom” center channel effect. In addition to imaging improvements, toe-in can also change your speaker’s tonal balance (or timbre). For that reason, you may want to play with toe-in to get the most out of your speakers.
do not directly radiate toward the listener. With surround speakers, some reflection is intended before reaching the listener’s ears. Your home theater preamplifier/processor may have additional suggestions for surround speaker placement, especially if there are multiple surrounds (as in a 7.1 arrangement). In general, a diffuse (rather than direct) surround speaker positioning allows your ears to anchor primary sounds in the front which makes for a better overall home theater experience.
your subwoofer is placed, it should not be easily localized, but should instead produce a balanced and enveloping response. Factors that can affect performance in relation to placement and localization of the sound are rattles from shelves, walls, or other nearby objects, as well as distorted output. If you are having issues with subwoofer localization, try to isolate any rattling or buzzing objects, or place the sub in another corner of your room.
Speaker Placement Alternatives In a perfect world, you have a room dedicated only to your audio/video needs and you can set up the room to suit the needs of speaker and equipment placement. Well.., that’s in a perfect world and at AV123 we are aware that most rooms have other uses too. This means we’ve considered some alternatives to speaker placement and/or mounting that may help you blend the ideal placement with a realistic solution for your application.
Stand Mounting If you’re placing your AV123 x-ls monitors speakers on stands, you have several options: • Ideally, you would use the threaded inserts in the bottom of the speaker cabinet as a way to secure the x-ls monitor to the stand using the appropriate hardware. This approach would be the most secure as far as traffic and routine house cleaning is concerned because the speaker and the stand become one.
Connections For the best sound quality and signal transfer, AV123 recommends a minimum of 16 gauge high quality, multi stranded, oxygen free copper speaker cables. Speaker wiring connections are accomplished through the 5-way binding posts. Left/Right Connections To To Connect the amplifier’s LEFT channel outputs to the positive and Amplifier Amplifier negative input terminals of the LEFT x-ls/x-cs monitor or x-sls/xNegative Positive mtm/x-pls tower, being sure to observe correct polarity.
Line Level Inputs If your receiver or preamplifier has a set of full range RCA line outputs that are not already being used, you can connect these into the LEFT and RIGHT Line Input jacks (pictured at right in the illustration). When using these inputs, the crossover is still active so a full range input will be filtered to allow only the lowest frequencies to reach the subwoofer.
Calibration Calibrating your speaker levels will ensure that the effort you’ve taken to correctly position the speakers themselves will pay off when you finally sit down to enjoy them. SPL Measurements To accurately calibrate levels, you’ll need an SPL meter. Radio Shack sells a digital meter that works very well for this purpose (P/N 33-2055) and it’s about $50. Set the meter on ‘slow’ and “C” weighting.
5) Begin by setting the levels of the main, center, and surround speakers one at a time. While pointing the meter toward the speaker active with the test tone, set each channel to the same reference level while the SPL meter remains in the listening position. Your goal is to establish an even output level of each speaker to that spot. Setting Subwoofer Gain 6) Once finished with the other speakers in the system, direct the test tone to the subwoofer.
crossover in the x-sub/x-pls. Begin at the highest setting (150Hz) and slowly dial it down until it seems as if the bass is anchored in the front speakers rather than just the subwoofer. We strongly recommend settings above 80Hz because this will allow a nice blend with the other x-series speakers without making them work too hard with reproducing the bulk of the low frequencies.
