I've been eyeing line arrays for a long time. I've wanted to build a set but time never allowed itself.
It is time to replace my Def Tech 7002's. I found a pair of LS6's(from AV123) for sale but have never heard them. I've heard all kinds of great things about them but a blind purchase is still a blind purchase.
I have heard the DefTech ST's and both speakers fall within my budget, the LS6's actually begin less expensive.
I know this is a hard question and I'm not looking to start a "this speaker is better than that speaker" discussion but it looks like on paper that the LS6 should be a better all around speaker, but again I've not heard one and have heard the other.
I've got to go 11 hours to hear the LS6's.
My room is 20x20 with sloped ceilings from 14' at the edges to 20' at the peak, so those good with math can figure the angle

The room is open, it opens into the foyer and loft area. Split between HT and music.
I have no sub but I'll add one or two.
Right now I just have a Yamaha A-1000 but I'll be adding separate's. The A1000 does all I want audio wise but doesn't have the power that my older RX-V2600 had so I'm looking some amps in the 125w range.
The price is right on the LS6's, and actually on most of the LS series that I've seen for sale.
WAF is no consideration, she actually asked me if I was going to be OK 'settling' for the 6's vs the 9's.
So my mind says the ST's are a safe bet since they are local, I've heard them, etc...but what am opportunity am I giving up for the risk of buying the LS6's basically blind is what goes round and round in my head. I know I need a sub but I'm looking at about $800 less for the LS6's than the ST's which should give me a good headstart on a decent sub.
