Let add another vote along with MikeKaz & DonnyD about the CEA Innovations 2000 Design and Engineering Award Winner JBL S38's.
Specifically this Studio Series loudspeakers utilize many of the same leading-edge testing and design technologies included in our Professional Series LSR Linear Spatial Reference studio monitors**, and allow home listeners to enjoy the same neutral, uncolored, detailed and spatially accurate sound quality heard by the pros.
**JBL LSR28P - 1999 TEC Award Studio Monitor Technology Winner
The JBL S38 & S36 is designed after the JBL LSR32P
Phil,
You sound like a walking JBL Spokesman! They should give you
a job because you do such a great job as it is (for free!)
You are worse than I am with AR stuff.. heh
If it was me I would go with the AR15's and mount them
horizontaly (which you can easily do as the tweeter's
acoustical ring will disperse the same from any orientation)
But that's just me
