Lad,
This thread is stale, but I thought I'd chime in as an M4 Turbo S owner with now about 200 hours on them and they simply wonderful.  I hooked up my REL T-7 sub and it sure fills out that the lower octave in a way that makes the sound presentation come alive.  They are very easy to drive with a 7 wpc tube amp, but also sound wonderful with a CJ solid-state amp.  I could't be happier wit the sound I am hearing.  Cheers, Mark
Mark - Whitestix,

Did your M4's experience a break in period whereby the sound changed and/or improved over time?
Thanks,
Randy
For what it’s worth, I haven’t tried corner placement. I think you’d have to ask Clayton whether that was a good idea. He recommends either a far-field or near-field placement – and these options are detailed in the Owners Manual. On the other hand, my setup isn’t exactly compliant with either of those two set up recommendations, and I’m getting great results. I think there really is something to be said for the "controlled directivity" concept as implemented here in terms of "taking the room out of the equation" with placement.
Frankly I am amazed more open  baffle designs are not in systems everywhere. There is no going back when you lose the box unless you spend big dollars. Nice review!
