High-performance active dual subwoofer for professional studio monitoring.

The Sub A225-M is the perfect addition to any PSI Audio speaker setup. No matter if you are working with our compact A17-M or the large A25-M, the A225-M will seamlessly integrate with all our monitors. Simply engage the bass roll-off on the satellites and enjoy a full-range system that extends down to 24 Hz with all the linearity in frequency and phase that you are used to from our monitor speakers.

For those who want more than just “some bass”: the A225-M is the ideal addition to any PSI Audio monitoring system, granting the same trademark fidelity to the lowest frequencies

Designed to complement our large three-way systems, the A225-M packs a lot of power to support full-range listening without compromise. It can also extend a smaller system, of course, or even mixed setups like in surround applications as the LFE. The A225-M is at home wherever low frequencies need to be monitored reliably, like in mixing, mastering and post-production.

Quick service and reasonable price. Angus was helpful and transparent.20/07/23 Update. I had an issue with some equipment that I purchased from these guys, and true to form, they were supportive and gave me consistent feedback on the progress of my concern. Elliot and Darren were incredibly committed to getting me a satisfactory result. I have recommended Factory Sound to my mates because I actually believe that they will be taken care of.

The only place to buy pro audio gear from. Been coming here for over 20 years, and a lot of the same staff still look after me. Says a lot about their business. The best service, advice and gear every single time. If they don’t have it, they’ll get it for you. No need to worry about pricing, theirs is ALWAYS the best. All the staff go out of their way to help you, and will always get back to you. Cant’ recommend this place enough, 5 stars doesn’t seem like enough.
