Target Sound Options
Once the room measurements are completed, MultEQ® Pro calculates an equal- ization filter for each loudspeaker channel, including the subwoofer(s). The role of these filters is to achieve a particular frequency response within the entire listening area for each loudspeaker. This curve is determined based on several acoustical and program material considerations and is called a target or calibra- tion curve.
Contrary to popular belief, a target curve that is flat from 20 Hz to 20 kHz is not always the one that will produce optimal sound. There are several reasons for this including the fact that most loudspeakers are much more directional at high frequencies than they are at low frequencies. This means that the balance of direct and reverberant room sound is very different at the high and low ends of the frequency spectrum — something that should be accounted for in selecting an appropriate target curve.
The Target Sound Options screen allows you to determine the end result you would like to hear, after MultEQ® Pro has finished calculating the corrections needed to get you there. The four curves are used as follows:
•The Flat curve creates equalization filters that correct the re- sponse to flat from the low frequency cutoff point that MultEQ® Pro has determined to the upper frequency limit of the tweeters. This setting must be used in a THX system in order to allow THX
•The Standard HF Rolloff curve introduces a gentle attenuation of high frequencies that accounts for the balance between direct and reflected sound for most domestic rooms. This is the recom- mended curve for Wisdom Audio speakers under most circum- stances.
•The Gaming curve adds some boost below about 40 Hz to enliv- en the gaming experience. While technically less “accurate” than the Standard HF Rolloff curve, this option is unquestionably fun and exciting. Be certain your subwoofers can handle a little extra
