Room Correction Taken One Step Further
Using the iWoofer Pro app (iOS only), you can automatically tune your sub to your environment. The paid Pro app version features automatic room correction, which utilizes minimum phase FIR filters to adjust your subtone for optimal low-end response based on your listening environment. Using your iOS device's built in microphone, the iWoofer Pro app will monitor the frequency response of noise sweeps played back from your sub to build a frequency response plot of your room. Once iWoofer measures your room's frequency response, you have three algorithm options in how to tune your sub, Boomy, Near Field, and Linear.
Compensate for room reflections, which often create the buildup of low-end in areas of your room by employing the Boomy auto-room correction mode. Using the Boomy algorithm, you will notice that your subwoofer will have more punch and defined low-end. The algorithm compensates for any frequency that will make your system sound muddy by flattening out the bass response from 70 Hz and higher.
The goal of the Near-Field auto-room correction mode is to provide DSP compensation to make your sub sound as if it located in an ideal room with no reflections. Near-Field mode is excellent for a clean and accurate representation of your subwoofer with flat bass response. While possibly sounding duller than the other modes, Near-Field mode delivers a true room correction option when you are looking for an incredibly flat low-end response from 30 - 185 Hz. Near-Field mode is excellent for critical listening.
Linear auto-room correction mode will adjust the sub output so that the frequency response is more accurate, especially in the 50-70 Hz range. This mode will deliver a flat midbass response while leaving the lowest frequencies as they are. The linear algorithm provides a bass tone that is more transparent, controlled, and detailed.
