XJ-700-DSP - LFE Mono Block Amplifier with Built-in DSP Module

The XJ-700-DSP has a unique built-in Boundary EQ designed to remove exaggerated boomy sounds created by corner loading, large wall surfaces, or installations inside custom cabinetry; other amplifiers try to equalize the room only by adjusting the volume. This amplifier addresses the actual phase correction problem along with the room EQ. The XJ-700-DSP can also power multiple tactile transducers like Earthquake’s Q10B, as well as high response subwoofers like the patented THOR in-wall shallow subwoofer making it an extremely versatile option. Additionally, users may also connect any other passive subwoofer/s to this amplifier.

The XJ-700-DSP is ideal for handling heavy-duty subwoofer applications to driving the equipment of everyday home audio enthusiasts and professionals. It was designed to exceed the highest expectations in audio amplification for folks who desire full control and ability to adjust all parameters of operation. With the new XJ-700-DSP, a customized room response has never been easier.

The minimum rated impedance is 4-Ohm total. On the actual amp it specifies 4-Ohm minimum on each terminal.
These terminals however operate as one
meaning that you can either put a 4-Ohm load on one of them and none on the other OR put an 8-Ohm load on both of them
resulting in a total impedance of 4-Ohm.
