I've always like yamaha stuff - bikes, boats, stereos, guitars, keboards, etc. Never been disappointed.
I almost got the dxs18..but i'm not a bandpass fan. I have the yamaha stagepas 600 for ceremonie's and smaller gigs and 2 ev zxa1 12" subs for use with it (or my older passive setup). Really lets those tops sing and balances them well.
The DJ i bought out had mackie S505 tops and 2 mackie 1400i amps and an old peavey sub. I'm rebuilding the sub (was going to use it as a ported, previously bandpass, till I got the school dance and just figured WTH, it's only money, go big or go home..that and the DXR12's are SOOO much louder/better than I had anticipated.). the mackie stuff is 15 years old - still works just fine.
Have to decide what to do with it...backup, second rig, sell it...it and the peavey PR12 and 15 tops I have I'll probably keep for outdoor gigs. Or if my son and his friends do start a band they'll have a PA.
