Dual Mono

L1 Model II

L1 Compact

Introduction

This article pertains to Dual Mono with L1 systems.

L1 Systems

The L1 systems have extremely wide horizontal dispersion. As a result, running multiple L1 systems in the same sound field may result in overlap. The comments below are applicable in that context.

Non-L1 Systems

The F1 Model 812 Flexible Array Loudspeaker and S1 Pro System systems have narrower horizontal dispersion. If you space those systems apart or aim them to avoid overlap, this article is not applicable.

Dual Mono

This is amplifying the same sound source through two separate loudspeakers.

Dual mono (with the L1 systems) is usually not a good idea, if you have more than one performer. With more than one performer/source it's in my opinion always preferable to separate the sources (i.e. one source per L1). The spatial separation and precise localization help more with clarity much more than the added gain.

For a single performer/single source it's not quite so clear cut. One will be more accurate (i.e. sound is clearly located at the performer's position, more consistent spectrum) and two will sound wider and more spacious. In the end, that is an artistic decision, depending on which one is closer to your artistic intent.
