Dayton Audio's DSP-LF Low-Frequency DSP Controller gives you the power to revolutionise your home theatre or listening room's low-end dynamic using digital signal processing. Easily integrate the DSP-LF into an existing audio system and take control over your bass response all from your smart mobile device. In tandem with the free iWoofer, Android/iOS app, the DSP-LF puts you in control of your bass's sonic character, tailored perfectly for the sound you desire.

Simple, Straightforward Installation and Operation 
Installing the DSP-LF hardware is hassle-free and straightforward. Featuring a 3.5 mm input and output, the DSP-LF is easy to connect to your current system. To control your DSP unit, download the iWoofer app from Google Play or the Apple App Store. Once the DSP-LF connects to iWoofer via Bluetooth, you immediately have complete control to customize your low-end to your preferred taste. The DSP-LF comes complete with two dual RCA to 3.5 mm cables. 
Insert the DSP-LF between the sub output on your receiver and your powered sub (or sub amp) input to gain instant control over your desired sound. The free iWoofer iOS/Android app allows you to adjust parameters such as EQ, crossover, subsonic filtering (high pass filter), gain, dynamics, precise phase, and even subharmonic synthesis. 
For further detailed control, iWoofer Pro (iOS only) offers automatic room correction that listens to the response of your subwoofer in your room and automatically applies precise minimum phase FIR filters to correct the output of your sub to match your listening environment. 
 
Total Custom Sub Sound with App Convenience 
Using the iWoofer app, you have command over your audio system from the convenience of your smart device. With control over functions as EQ, crossover, gain, dynamics, precise phase, and even subharmonic synthesis, you can tune your sub to deliver the sound that you want. The iWoofer Pro version (iOS only) offers automatic room correction, which is a great option to dial in an even more defined subtone. 
The standard, free iWoofer app allows you to adjust both high and low pass Butterworth filters with adjustable slopes to find the perfect crossover. The crossover control also allows you to add up to 25 bands of fully parametric EQ. The gain function gives you control over the volume of your sub, complete with an Auto-On feature. If your audio source lacks a low-end response, the SHS (subharmonic synthesizer) control will help add more punch and depth to the overall low-end output. Controls over delay and phase allow you to tune the sub to align acoustically with other full-range speakers in your current setup. Access to dynamic processing enables you to limit the output signal, or with the dynamic bass control, you can restrict your compressor to a specific frequency bandwidth. 
Save, import, and export presets within iWoofer so that you can recall your perfectly tuned sub in an instant. Presets allow you to have multiple configurations based on your listening selection. 
 
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 is located in an ideal room with no reflections. Near-Field mode is excellent for a clean and accurate representation of your subwoofer with a 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. 
Once the auto-correction is complete, as seen above, you have further control over the DSP. In the graph above the blue line shows the Near-Field measurement of the subwoofer, the green line shows the initial measurement of the listening position before correction, and the red line shows the corrected response at the listening position. Each algorithm is customizable after the initial room correction with up to 25 bands of additional EQ so that you can adjust the sound to your needs with extreme accuracy.
