  1. Subwoofer SPL reading is too high to EQ to 75-80

    Subwoofers, Bass, and Transducers
    Hi there, I just synched up my four subs using the delays in MiniDSP. Now my issue is EQ. My SPL readings fluctuate above the 75-80 range. This makes it impossible to EQ. Any ideas what I should do to calibrate this? Did I miss anything? I am following the suggestions from the Hour and a half...

  7. Bookshelf speakers: Max SPL at lower frequencies?

    Audio Theory, Setup, and Chat
    Hi, When discussing subwoofers, it's often mentioned what SPL they can reach at different frequencies. But what about other speakers, such as bookshelf speakers?
