This is not a subwoofer
At least not in the way most people think about subwoofers. In many cases, the leading questions that govern the development of a subwoofer are “how low can it go?” and “how loud can it go?” At PSI Audio, we did consider these questions, but we added a third one: “how precise can it go?” With typical subwoofers, all you get from the low end is some vague rumble. This can be impressive, but it is not particularly musical.
With the A125-M, you get the power and the depth, but you also get the punch, the transients, the speed and accuracy that you can expect from a PSI Audio product – which is why we like to think of our subwoofers as “low-frequency precision monitors”.
