| There are limited options when comparing output, quality and size. The L-Acoustics dV-DOSC is probably a direct competitor. The d&b Q10, Nexo GEO S8/12, EAW KF730, Martin W8LM, SLS LS8800, etc. are not powered. The QSC WideLine has, as the name suggests, a wider than normal nominal 140 degree pattern, this could be good or bad depending upon the situation.
I could be totally misunderstanding things, but it almost sounds like this may be being approached in what is usually a less than optimal fashion. I say this based on the comments regarding the questions on the number of subs and which model to use, as well as your general question on whether the M'elodie is enough for the application. Rather than picking products and then trying to fit them to the application, it is often better to first define your goals and then determine which products can support those goals. For example, whether the M'elodie is sufficient requires knowing what defines being sufficient. Are there any specific design criteria or goals your system designer is trying to achieve or are they just suggesting products rather than trying to achieve any specific result?
How much of your service is speech and vocals? I personally do not like split stereo systems for many venues as any mono sources are routed to both arrays, which typically results in interactions between the signals from the two arrays that lead to issues like combfiltering and a low frequency 'power alley'.   |
