I own a pair bought used.
4 years with indoor and outdoor use.
For me a very good compromise Nexo Alpha E (more expensive)
The advantage: Dual amplified with a REAL serious.
Acute medium-module is equipped with a 26 cm flag, is an acute compression of 2-inch center-mounted flag a medium (hence coaxial), precise and consistent.
It has 2 serious hp 46cm mounted in a box semi flag: it gives a good bass sound with great fishing and impact!
Simple and fast to use: the heads land on the subs, it connects to Speakon 4pts, it's reliable and with great sound.
I did a lot of concerts and festival is GREAT!
As always we must not neglect the amps and the wiring for his son, but the quality / price / simplicity and reliability is excellent.
