The A23-M is a compact 3-way active studio monitor, designed as a mid-field (or near-to-midfield) monitor.

The A23-M is especially well-suited for:

• Mixing and mastering in small to mid-size studios: thanks to its accuracy, flat response, and good low/high bandwidth.
• Midfield monitoring – rooms of modest to medium size where nearfields are too small but full “mains + sub + mains” setups would be overkill.
• Broadcast, post-production, editing workflows: its pinpoint imaging, phase coherence, and wide dynamic range suit critical listening.
• Flexible setups or variable studio spaces – the rotatable module helps if your monitors need to fit unconventional spaces or be wall-mounted/horizontally placed.
• Quality-conscious project studios / home studios where budget or space constrains but you still want reference-level monitor performance.

The A25-M delivers a set of features that make it a serious reference monitor – beyond “project studio nearfield” – but close enough to be versatile for many professional uses.

The A25-M is especially well-suited for:

• Professional mixing and mastering – thanks to its accuracy, wide frequency range, dynamic headroom, and transparency.
• Midfield or main monitoring in mid-to-large-sized control rooms – where nearfield monitors are too small and large “mains + sub” systems are either overkill or less practical.
• Post-production, broadcast, or immersive audio work – its power, dynamic range, and neutrality help with demanding formats (multichannel, immersive, high-SPL monitoring).
• High-end personal studios / project studios where quality matters – for engineers/ producers who want reference-level monitoring without going to “giant studio main speaker + racks” setups.
• Flexible installations – thanks to the rotatable driver module, you can place speakers vertically, horizontally, or adapt to room constraints (wall mount, console side-mount, etc.).

The A226-MAIN is the flagship “main / mastering” monitor from PSI Audio – its largest, most powerful active-analog three-way studio monitor.

The A226-MAIN is especially well-suited for:

• Mastering studios – where transparency, neutrality, full-range response, and consistency are critical.
• High-end mixing rooms (music, post-production, broadcast, film, immersive) – especially when you have a properly treated room and enough space to let the monitor breathe.
• Immersive / Dolby Atmos / 3D / multichannel setups – due to its wide frequency response, high SPL, and stable stereophonic image.
• Large control rooms or professional environments where powerful, accurate, full-range sound is needed.
• Serious personal listening environments – for audiophiles or professionals who want “reference-grade” sound even at home.

The A326 D-REX is not a “regular” subwoofer: it’s a Dynamic Range Extender (D-REX) designed specifically to complement the A226 MAIN monitors.

The A326 D-REX is especially well-suited for:

• Mastering studios – where accurate bass and low-end dynamics are critical.
• Film / post-production / immersive audio studios – deep bass, LFE, sub-bass effects need precision and control.
• High-end music mixing studios – especially for genres with heavy low-end (electronic, hip-hop, orchestral, cinematic).
• Large control rooms or broadcast rooms – where high SPL and full-range coverage are needed without sacrificing neutrality.
• Audiophile or high-fidelity listening rooms – for listeners who want accurate, full-spectrum playback with low-end extension and dynamic realism.

The A225-M is an active subwoofer / bass-extension from PSI Audio – meant to extend the low-end of A23-M and A25-M or any PSI Audio monitor system down to deep frequencies.

The Sub A225-M is especially well-suited for:

• High-quality mixing / mastering studios — when you want to extend the low end beyond what the main monitors can handle, but still with reference-grade accuracy.
• Full-range monitoring systems: When you combine PSI monitors + A225-M, you get a system covering from deep sub-bass up to high frequencies – great for music production, film audio, sound design.
• Bass-heavy genres or content: Electronic music, hip-hop, cinematic soundtracks, EDM, film sound – anything where sub-bass content and low-frequency control matter.
• Project studios & professional environments that demand accurate, neutral bass reproduction (rather than colored or exaggerated low end).
• Immersive / surround / Dolby Atmos–ready installations – thanks to optional LFE module and proper phase/response alignment with PSI monitors, A225-M becomes a dependable low-frequency component for complex multichannel systems.
• Professional broadcast / post-production / film studios where accurate sub-bass and LFE monitoring is critical.
