SA-1 Subwoofer Amp   Sold Out

The SA-1 amp will output 200 watts into 4 ohms and 110 watts into 8 ohms.

It is also very small and will fit on the back panel of even a narrow shaped speaker. It measures only 7.125" wide and 10.625" tall.

It has a removable IEC and will work with 110 to 120 volts or 220 to 240 volt power.

It also has high level and low level inputs so it can be sent a signal via RCA or speaker level inputs. There is also a LFE input (via RCA) that will completely by-pass the crossover controls and shaping circuit.

The really unique thing about this amp is the output response. A special gain circuit has been designed that will mirror image the roll off of a sealed box or open baffle design.

The lines above show various setting on the infinitely adjustable crossover control.

As you can see, with this amp, you can get a -3db in the low 20's with the right open baffle woofers or sealed box woofers. It is also ideal for use with our SW-12B woofers:

There is also a high pass filter built in to keep from over driving the sub with information below 20Hz.

These amps will also come with the new V-2 loudspeaker kit seen here:
