Intermezzo 1.2s

1.Select a new test position: Cue the test track corresponding to the center frequency of the dip. In the first example in Figure 18, you would play Track 13 (56Hz). Press Play Ý. You will see a reading very close to what you had before. Now, slowly move the RSLM around the area, if possible remaining within about a foot of the original test point. As you move the RSLM, watch the bar graph. You will observe large level fluctuations. Find a position that restores the level to approximately that of the adjacent test points. You may find it helpful to move the RSLM vertically. Dips can be oriented in any axis. The position that restores the level to about that of the adjacent test points is your new test position.

2.Reset the test level: Return to the section “Setting the Subwoofer Test Level” on page 11. Perform the procedure as described.

3.Repeat the measurements: Now that you are familiar with the measurement process, you can go much faster by using Tracks 27–50.These tracks contain all the test tones necessary for measurement. However, each test is only about three seconds, and there is no frequency announcement.The first test is 100Hz. Just place each test mark in order until finished. Connect the dots.

Your second measurement will no longer exhibit the deep response dip. However, the peak will still be evident. Without the influence of the response dip, the amplitude and center of the peak may have changed. Compare your new data to the examples given in this section of the manual. Follow the instructions for the example that most closely matches your new measurement.

Example 4. Narrow Response:

FIGURE 19

Narrow Response

Although it looks as though this speaker is quite bass-deficient, this is actually indicative of a single, very narrow peak in excess of 10dB high.

Apply the Width Selector as described above. Align the center-line of the Selector over the center of the peak, as shown in Figure

14.Now adjust the Selector until you have achieved the “best fit”. The slider now points to the correct width setting. In this example, the frequency is 40Hz and the best-fit width is 10%. Fill in the Width and Frequency fields provided on the template.

Determine the appropriate level using the technique described earlier. In this example, -13dB is indicated. Enter 13 in the field provided.

Skip to the “Adjusting the R.A.B.O.S. Equalizer”section on page 18.

Example 5. One or More Narrow Dips:

Example of two narrow dips

Response dips can occur at any frequency, sometimes immediately adjacent to the peak you want to correct. In this example, there are two such dips on either side of the peak. Deep response dips such as these are caused by destructive wave interference. Destructive interference dips occur only in one spot within the room. It is not uncommon to completely eliminate their effect by moving the RSLM to a different location. Note that this does not eliminate the dips. We have simply moved away from them. Sometimes only a few inches are required. Do not attempt to correct this condition with equalization. If you encounter dips like this, take the following steps:

1.2s specifications

The Infinity 1.2s is a revolutionary advancement in the world of audio technology, specifically designed for audiophiles and sound enthusiasts who demand superior sound quality. This state-of-the-art speaker system boasts a range of features that ensure impeccable audio performance, making it a popular choice among professionals and casual listeners alike.

One of its standout characteristics is its exceptional frequency response. The Infinity 1.2s is engineered to deliver a wide frequency range, allowing it to reproduce both deep bass and crisp treble with remarkable accuracy. This enables listeners to experience music as it was intended by the artists, with each instrument and vocal nuance clearly pronounced.

Incorporating advanced driver technology, the Infinity 1.2s features a combination of woofers and tweeters that work in harmony to create a balanced sound profile. The woofers are crafted from high-quality materials to minimize distortion while maximizing bass response, ensuring that low-frequency sounds are powerful yet controlled. Meanwhile, the tweeters employ cutting-edge technology to deliver high frequencies that are both detailed and smooth.

Another significant technology embedded in the Infinity 1.2s is the innovative crossover design. This sophisticated crossover network effectively divides audio frequencies between the woofers and tweeters, which enhances the speaker's overall performance by ensuring that each driver operates within its optimal range. The result is a seamless transition between low and high frequencies, producing a cohesive sound that is rare in many consumer-grade speakers.

The build quality of the Infinity 1.2s is also noteworthy. Constructed from durable materials, the cabinets are designed to minimize resonance and vibrations, which can muddy sound quality. This focus on sturdy construction not only enhances audio fidelity but also contributes to the longevity of the speakers.

Furthermore, the Infinity 1.2s is equipped with versatile connectivity options. It can easily adapt to various audio setups, whether wired or wireless, offering compatibility with a range of devices and systems.
