I just finished installing a bar in Morocco loundge here's the config of the place:

1x Allen & Heat Xone Mix 62
1x Denon DN4500 CD
1x BSS FDS-334T MiniDrive
1x ECLER MPA 6-80
1x QSC RMX 850
4x sub HK Audio Premium PR: O 18X
Newtec 12x Cono Alto Audio (This is a brand to discover: HP ceiling with a spread of 360 ° sound is amazing how the sound is clear nickel!)

I removed the filters passive subs because the management is entrusted to the HP MiniDrive and subs sound of thunder! I did a test with and without passive filters and housings are not even safe in the low ... happiness!

The set is super consistent and if it shakes up the sound a serious place 120 people max!

I therefore strongly recommend these boxes, as HK!
