How does this compare to the audiocontrol epicenter?

a bass knob works in one of two ways. 1. a remote gain adjustment that laters the impedance of the input stage of the amplifier 2. (most common) a remote amplitude cut/boost (voltage) adjustment to a fixed (or variable) frequency point with a fixed Q (slope.) It's like a remote EQ slider. The Epicenter is a digital bass restoration device. You send the Epicenter a full range, uncrossed over signal. The epicenter looks at this signal and computes, based on higher octaves, what it believes should be present in low frequencies. If bass frequencies are already present in the source material, the Epicenter won't add anything. . It uses some subharmonic algorithms to figure out what it thinks should be present in the low frequencies based on what it sees in the higher frequencies. You choose on the Epicenter what range of frequencies you want to adjust, both the center point and how wide of a range to adjust. That is done on the unit itself with 2 knobs labelled 'wide' and 'sweep'. Directly from Audiocontrol - "The Sweep knob allows the user to pick the center frequency of the bass restoration. With the Sweep knob turned all the way to the left, The Epicenter® is centering restoration on 27Hz. With the Sweep knob turned all the way to the right, The Epicenter® is centering on 63Hz. The middle position represents approximately 45Hz. The Sweep knob can be set to center The Epicenter®'s restoration anywhere between 27Hz and 63Hz. The Wide knob allows the user to control the width of the restoration. With the Wide knob turned all the way to the left, bass response is tighter and harder hitting. With the Wide knob turned all the way to the right, the bass response becomes more booming and open." Once you've tuned the unit to 'boost' (create) bass in the right frequency range, you then adjust how much restoration you want by turning the knob that is mounted in the front of your vehicle. Because the epicenter takes an uncrossed over signal to work correctly, you must cross over your signal AFTER the epicenter, which means if you are using crossovers on your head unit, you'll need a full-range output for the Epicenter, or you'll need to switch to an external crossover. Along with this digital bass restoration, the epicenter functions as a line driver, yielding up to a 10 volt output. It supports both balanced and unbalanced inputs. You can make ANY music absolutely thunderous with the epicenter. You can also drive your amplifier into HARD clipping EXTREMELY easily if you do not know what you are doing. The Epicenter is a bass-head's toy, not much more. Using it on some music results in muddy worthlessness. Using it on other music results in sickeningly deep, punchy and consuming bass. It's hit or miss, and you only get to tune the frequencies in which to recreate bass on the unit itself, so you can't tweak it for each song. You've just got the ability to turn it 'off' or adjust how much it recreates by turning it up. It's a glorified parametric EQ merged with a harmonic bass restoration device.
