this is 6 months I use this system consists of 4 resolution 4, 4 and 2 F218 Infrabass all amplified in FFA.
We try several before notte JBL SR system, JBL SRX ...
Plus: The fineness of its power and almost infinite room.
Minimum: Scarcity in the middle
Good value for money when you want the true quality certainly a little expensive for start in the middle
I would do this choice with his eyes closed since we will further develop our system in the next month.
