RoomEQLab is run by Derek Anderson, a home cinema and hi-fi enthusiast based in Scotland.
Why I built it
Room correction is one of the biggest upgrades you can make to a system, and one of the most confusing to get right. The good information is out there, but it is scattered across manufacturer manuals, help centres, forums and Facebook groups, and a lot of it contradicts itself.
I found myself answering the same questions again and again in Dirac and AV groups. So I decided to write the answers down properly, in one place, with the sources linked, and make them free for anyone to use.
My own system
At home I run a dedicated cinema room with Dirac Live, including Bass Control and Active Room Treatment, and three subwoofers. The guides aren’t about my kit, though. They cover every major room correction system, whichever brand you own.
How the guides are written
- Every step is based on the manufacturer’s own documentation, and the sources are linked on each page.
- Where advice comes from user experience rather than the manufacturer, the guide says so.
- The guides are brand-neutral. RoomEQLab isn’t affiliated with Dirac, Audyssey, Yamaha, Anthem, Lyngdorf, Sonos or any other manufacturer.
- Each page shows when it was last updated, and I revise guides when firmware or software changes.
How the site is funded
RoomEQLab is free, with no sign-up, no adverts and no affiliate links. No manufacturer or retailer pays to be included. See the Advertising Policy for details.
Spotted a mistake?
If something in a guide is wrong or out of date, post it in the RoomEQLab thread on AV Forums and I’ll correct it. I can’t offer one-to-one setup help, but Troubleshooting and the FAQ cover the most common problems.
