“The A25-Ms are genuinely revealing monitors that can provide great insight into the components of a mix and how they fit together, or not. I’ve no idea if it’s the CPR or AOI (or both) that are responsible for the abilities of the A25-Ms, or if it was simply good, traditional electro-acoustic engineering that I was hearing, but it seems to me the the number one priority of any monitor design is that it enables us to hear what’s what in a mix, and to help us make the appropriate creative decisions. The A25-Ms really excel in that regard.”

 – Phil Ward, Sound-on-Sound UK

Extend the Low Frequencies and Add Power

When used with one of our subwoofers, the A25-M will transform in an amazing 4-way system, with ultra precise control on all the frequencies, from very low until the highest notes:

• Our compact Sub A125-M (Two units are required to match SPL max of A25-M)
  
• Our full range Sub A225-M
  

"The A25-M exactly translates 1 by 1 my work. It’s the perfect main monitor for mixing and mastering."

– Pascal Brunko – Damp Studio
