Consider this a surface skim (and not an exhaustive list) of EQ applications and devices that might bring you one step close to audio nirvana, with the caveat that EQ isn’t a magic bullet and won’t ever strip away all of the room’s ills.
I’ve not experienced all that is out there to be tried and neither have I gone too deep. For audiophiles listening at home, that often translates to a software application running on a PC or Mac or dedicated code – digital signal processing (DSP) – running on a chip inside a piece of audio hardware. EQ in the 21st century is often executed in the digital domain. That leaves number 3 as the remaining weapon of choice in our war against modes and reflections. During last week’s video interview with Berlin-based studio acoustician Jesco Lohan, he listed three big wins in his battle against the negative influence of the room over a loudspeaker system: 1) speaker/couch placement 2) the installation of numerous absorbers, diffusers and bass traps and 3) Equalisation (aka EQ).įor the majority of readers, domestic harmony will immediately strike number 2 from the list and number 1 was probably set in stone a long time ago - although a revisit couldn’t hurt.
