“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.”

The Power of EXD
Our Extended Dome Driver (EXD) keeps the advantages of both dome and cone construction types while eliminating the disadvantages. When applied to the midrange, dome drivers tend to become either unstable in the middle of the dome, or too heavy due to more rigid material being used, and they can only ever offer a very limited bandwidth in the low end. Cone drivers, on the other hand, pose a relatively large weight in their composition of membrane, dust cap, spider and suspension, which limits SPL and can cause distortion. They also restrict airflow with heavy basket designs. Even the dust cap can add distortion to the reproduction. |
|
Our EXD midrange driver developed for the A25-M, however, combines a 4-inch, latex-and-graphite-infused paper cone membrane with a light polypropylene dome, both of which are directly connected to the voice coil. With the dimensions and weight ratio of coil and membranes optimised in this way, our EXD offers higher SPL at lower distortion, pushing the new A25-M even closer towards perfect accuracy. To further improve its performance, the new driver is built directly onto the rotatable baffle with no basket at all.
"I use my pair of A25-M as the primary monitors every day. They bring a clarity to the sonic picture that I struggle to hear with any other monitors. I know that I can always trust them to get an accurate translation anytime I pull up a new mix or mastering session."
