To be used in EASE Focus, a GLL needs to be compiled including a so-called “.author” file. These .author files are encrypted by AFMG explicitly for each loudspeaker model and sent to the manufacturer for GLL creation.

In general, a “model” refers to precisely one configuration of a loudspeaker with exactly one acoustic radiation pattern, the so-called “balloon”. Usually, manufacturers call this a “loudspeaker model” or “loudspeaker type” and give it a unique number within their portfolio.

We have introduced “variants” in order to reflect little modifications to a loudspeaker or loudpseaker arrangement in our licensing model.

• In our sense “variants” of a speaker are primarily different versions of the same device that the user can create by himself in the field. These are not fixed when shipping from the factory. This could be a rotatable horn, for example or left/right symmetrical versions that are mounted differently.
• We also consider it a “variant” of a device if its acoustic radiation behavior does not change. This is for example mostly true for the active and the passive version of a loudspeaker or for the install version using different mounting hardware.
• Another use-case for variants are specific subwoofer arrangements of two or three subs which have already been licensed as single models. If certain manufacturer-recommended setups are measured and provided as separate GLLs distincly then these can be authorized as variants.

We use the term “box-type” to speak of both “models” and “variants”.
