PSI Audio LFE Module for Sub A225-M - Option

LFE Module

Turn your Sub A225-M subwoofer perfect for immersive audio setups

Main Features

With a new add-on module for the Sub A225-M, we can now fully support immersive audio environments. For all Sub A225-M built from September 2022, the LFE Module can simply be installed in place of the blank panel on the speaker. For older versions, an upgrade is possible but does require modification by the specialists at PSI Audio. With a frequency range of 24 to 160 Hz and output levels adjustable from -10 dB to +10 dB, the Sub A225M with the LFE Module is the perfect low-frequency companion for Dolby Atmos and other immersive formats.

Turn the A225-M subwoofer into a proper LFE speaker

With a new add-on module for the Sub A225-M, PSI Audio can now fully support immersive audio environments and is Dolby Atmos compliant.

One thing that remains unchanged by the LFE Module is the acoustic performance of the Sub A225-M. Low-frequency playback is more than just moving a lot of air; it is about capturing fine details down to the fundamental frequencies. Especially in immersive setups, a crisp and tight low end is paramount, as it is all about spatiality, sound location and imaging to create that effect of immersion. PSI Audio excels at reproducing the low spectrum. The flat frequency response and linear phase response recreate a very natural sound stage – just what you want in an immersive setup. The Sub A225-M with its LFE Module can add range and power to the bass, but its main focus is to bring out the low frequencies more transparently, to convey all the information in the bass spectrum with the precision and fidelity that you would expect of a studio monitor – especially one from PSI Audio. The Sub A225-M delivers a robust low end that still shows all the contour and delicate detail of the signal, and with the new LFE Module it complies with Dolby Atmos LFE requirements.
