Compact Subwoofer
WITH PRECISE 10" DRIVER
The main monitors have a variable roll-off that reduces low frequencies by up to 10 dB. With this roll-off, the speakers and the subwoofer are perfectly in phase and the frequency response is completely linear. Its sound pressure level makes the A125-M the ideal partner for smaller monitors such as the A14-M, A17-M or even the A21-M. If two subwoofers are used in a stereo arrangement, they perfectly complement the larger A21-M and A25-M models.
PSI Audio relies on sophisticated, practical analog technology for the A125-M, as for all its products. The double-walled wooden chassis with compact dimensions of 32 x 38 x 48 cm houses a 25 cm woofer. This is driven by a high-quality Class G amplifier, which ensures precise, efficient amplification and at the same time minimizes the heat load on the components. With a weight of 21 kg, the A125-M offers an extremely linear frequency response up to 28 Hz.
AOI, CPR, G/H - for highest quality
The A125-M has all the technical achievements that are built into the entire range of PSI Audio precision studio loudspeakers. This includes:
Adaptive Output Impedance (AOI)
This system monitors the diaphragm movements in relation to the input signal and thus enables exceptionally precise sound reproduction.
Compensated Phase Response (CPR)
This ensures that all spectral elements of the incoming signal are output in the correct phase in order to avoid unwanted changes in the sound of the source material. The entire technology works in an absolutely analogue way.
G/H power amplifiers
The same applies to the Class G/H power amplifiers, which combine the advantages of Class AB with lower distortion and increased efficiency.
Together with the Swiss craftsmanship and the complex calibration of each individual loudspeaker in an anechoic chamber, these technologies enable an unimagined precision in sound reproduction.
