Most EMMA competitors never hear the term ESQL until they're well into the Master class or chasing a spot at an international final. It's not something I get asked about at a typical local round, but it comes up enough from competitors looking ahead that it's worth laying out properly — what it is, how it's judged, and where it actually shows up.
What ESQL actually is
ESQL is a separate, higher-level EMMA Sound Quality format sitting above the regular SQ classes most competitors run in. It's been part of the official EMMA competition structure since April 2013, and it's built specifically as a Master-category format — it isn't something you drop into at Entry or Skilled level. If you're still working out where you sit in the standard ladder, my EMMA Sound Quality classes breakdown and the Master vs Entry €3,000 classes explainer are the better starting points.
How it's different from standard SQ judging
Two things set ESQL apart from the closed-door SQ judging most of us are used to:
- It runs last. The rulebook is explicit that ESQL judging doesn't start until the regular SQ, MM, ESPL and EMMA racing judging at that event has finished.
- It's judged in public. Rather than one judge and one competitor in a closed session, ESQL evaluation happens in front of an audience. That alone changes the pressure on the day — you're not just being scored, you're being watched while it happens.
Who's actually eligible
The entry bar is deliberately open rather than restrictive:
- The vehicle must be registered and self-propelled.
- It needs at least a proper driver's seat — this isn't limited to daily-driver interiors.
- Professional installation is permitted.
- Modified or custom-built equipment is allowed.
- There's no voltage limitation on the system.
That combination tells you who it's aimed at: serious, built-for-competition cars rather than stock daily drivers — closer to what you'll see discussed in my OEM vs Unlimited install categories piece, even though that's a different judging discipline.
How it's scored
ESQL scoring is a four-part process that gets aggregated into one final result:
- An installation check against the Master category rulebook matrix.
- Measurements taken with the doors open, microphone positioned at the ESPL measurement point.
- A tonal accuracy and spectral balance assessment, taken from 5 metres away using specified test tracks.
- A listening pleasure evaluation, played from the competitor's own CD at a moderate volume.
That last point is the interesting one — it's the only part of the process where you're not being judged purely against a reference track. If you want the detail on how a standard scoresheet is structured first, my EMMA Sound Quality scorecard breakdown covers the baseline version of this.
Where you'll actually see it run
I'll be straight with you here rather than guess: ESQL shows up at finals-level EMMA events — national finals and the bigger international stages, including events run under the EMMA Asia banner, which Australia is affiliated with (see my piece on what that EMMA Asia affiliation means). I haven't seen it run as a standard fixture at a local Australian club round, so don't go in assuming it'll be on the schedule at your next event — check with the organisers for that specific event, or get in touch and I'll point you in the right direction.
My honest take as a judge: don't chase ESQL until you've actually got a Master-level build and you're comfortable being judged with people watching. It rewards competitors who are confident in their tune, not just technically correct on paper.
If you're building toward Master class and want to talk through whether your current setup is realistically in that territory, get in touch — I'm happy to talk it through before you commit to an entry.
