Live End, Dead End (LEDE) is a concept that many, including Brian Cheney, VMPS founder/designer, have supported for many years. There are other acoustic ideas out there, including a more diffusion-rather-than-absorption idea that I like with my VMPS's. That means keeping the front (yes, front) soundstage lively yet diffuse by using diffuser drapes or diffuser objects that break up high frequency beaming, use bass traps to tame the low end, and use first reflection absorption, not front wall absorption.
To each his own.....and with all the different types of speaker architectures, I'd have a long talk with the speaker mfg'er about your particular room acoustics, your tastes and your speaker positioning. That will guide you toward a consistent room acoustics plan. That's the advantage of buying from mfg'ers who are accessible via phone, email or the net.
