Adventures in HomeCinema: Audio

The home cinema experience depends of course on the picture quality, but also the sound quality, if not more.
    Sound quality is directly reflected by your equipment and your subjective listening experience. Meaning more expensive is not always better for you, even though the equipment might be objectively measurable better.
    My 5.1.2 equipment:
  • Mains: Klipsch RP RP 280F
  • Center: Canton Center
  • Subwoofer: Klipsch R-112SW
  • Surrounds: Klipsch RP 402S
  • Atmos Ceiling: KEF T301
  • AVR: Denon X1600
My basic steps and AVR settings:
  • subwoofer crawl for finding a suitable place
  • Audyssey measurements
  • Set boxes to small and set the the LFE crossover to 120Hz
in the AVR android app (MultiEQ) are some more settings to change:
  • disable “Midrange Compensation”
  • set “MultiEQ Filter Frequency Range” to your rooms Schrödinger Frequency. This effectively restricts the AVR EQ to the lower frequencies.
The Schrödinger Frequency is the limit where your room doesn’t act like a resonator anymore. [1, 2] Bass frequencies up to 100-300Hz get amplified or negated, while everything higher disperses after some reflections.
    Seems easy enough, and sounds pretty good under most circumstances. Unfortunately some movies (for example Deep Water Horizon) that should be very bass-heavy sound / feel pretty tame. Will have to check how to fix this in the next post…
