    Shouldn’t we be looking more at PA speakers?

    I think companies like RME, Benchmark, Genelec, Neumann, Kali, and Meyer Sound have shown us that the gear marketed genuinely for studio/professional use can offer superior performance to “audiophile” brands with the obvious tradeoffs of looks. Audiophiles have also moved from the idea of...

    Finally, proof speaker cables can affect sound with sufficient difference to meet the audible threshold...

    In the same vein as this thread from @amirm, I found some data showing that different diameters of speaker cable can translate into differences in sound that reach the threshold of audibility. https://www.l-acoustics.com/wp-content/uploads/2021/10/RS2015-Cable_Effects.pdf TLDR? 1) It's great...

    Circle of Confusion: Database of Studios and their Monitors

    Out of curiosity, I started looking up the mastering/mixing gear used at some of my favorite studios. I thought it might be good to create a master thread where we keep track of what speakers are used where. I haven't separated the recording studio from the mastering/mixing studio, which is...

    Dirac/Atmos upfiring target + MultEQ-X question

    The current version of Dirac doesn’t properly support upfiring Atmos speakers in that it doesn’t distinguish between the initial impulse of the speaker versus the reflection which captures the ceiling height.
