My New Review of the Spatial Hologram M4 Open Baffle Speaker

I will report back. Just had my M1 upgraded with a new tweeter. Guess what there coming back in? New boxes at no extra charge. Now that's customer service.

Very intriguing speakers- thank for the write-up Rebbi.  I'm currently very happy with a pair of restored/upgraded MMGs in my small listening room- all tube electronics, as well as a pair of Sonus Faber Liuto monitors, but am quite tempted to avail myself of the 60-day home trial of the M4's.

And just when I thought I was "done."   :)

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

Anyone tried corner placement with any Spatials?
