The MAUI is better suitable for DJ work, but … at 999,00 each (and you need two) they are about 3 times as expensive as a Dave 15G3 systems (of which you need only one) for 660,00.
What you get is indeed array top end, D-class amp of 1.000W RMS per set (so 2.000W total for two) and integrated top stand as opposed to a double A/B-class amp of 700W RMS total, regular 8″/1″ top and no stands (available separately).
So, comparing apples and oranges. With your budget the MAUI is out of range (a long way).
There are a lot of manufacturers today that make affordable 2.1 systems that are (semi)compact and provide good price/performance reputation. So some more research might be necessary.
General rule of thumb to calculate needed power is:
* indoor = 5W RMS per person. For 200 persons that would put you at a minimum of 1.000 RMS. The Dave is too small. The Dave 18G3 would fit, but is not exactly compact and portable.
* outdoor = 10W RMS per person, i.e. 2.000W RMS total.
Double these numbers if you plan on going happy hardcore full steam …
