One consistently reported positive is the wide "sweet spot" the monitor has thanks to it's specially designed waveguide. They are also described to be "crystal clear" with regards to frequency response. They strike a great balance between enjoyable hi-fi listening and critical flat response that translates mixes.


Some users report noise and hiss from their units. Some wanted a bit more bass response.


The 308P is a natural evolution of the critically acclaimed LSR 308. With a more refined frequency response building on its predecessor's clear-sounding signature, the 308P is a great pick for small to medium studios.

Although this was previously on our recommended list, there are now more highly rated options available which you can see in our guide to The Best Studio Monitors.
