Stereophile reviews the active Grimm LS1C


A day before I started a thread on active speakers Stereophile published a review on the fully active Grimm LS1C. Fully configured (upper and lower sections) you are looking at $30k for a pair or more depending on finish.

There’s a lot I like about the design here, except the price, of course:

  • It’s aesthetically pleasing and doesn’t look like a monolith. It’s thin (front to back) and open.
  • Wide baffle (I’d rather have a wide speaker than narrow)
  • Woofer positioned very close to the ground.
  • Excellent off-axis performance ( a rare thing in high end speakers ) both horizontally and vertically.
  • Excellent recommendations for listening position and speaker angle given the tweeter used

I’m not sure I care about having a "perfect" response curve. Personally my choices have always been to apply EQ sparingly. There are systems like Dirac for instance that can hammer a speaker into measured frequency domain perfection but it’s the time domain performance that I find interesting.

The subwoofer is a bit of a mystery though. They make a big deal of the tweeter and midwoofer but the driver used in the sub is not listed. Given the size and claimed low end extension I suspect they are relying on the DSP to compensate for a cabinet that would otherwise be too small.

Would be really interesting to hear who has heard them and who would think this speaker was for them.

Time and audio march on.  We'll just have to wait and see what becomes of the LS1C. This does seem to be a new direction that audio is taking.

It's always interesting when a review and particularly the corresponding measurements section objectifies a loudspeaker as being nearly perfect. IMHO, loudspeakers are like human faces. How can there be a perfect; perception in this case is reality. 

I've heard the active Grimm speaker system (incl. the sub module) at a couple of occasions, and what has struck me with their sound fairly consistently is the coherency, tonal authenticity, balance, resolution and relative ease of presentation. There's an unforced "rightness" to the sound of the Grimm's that's difficult to articulate but nonetheless immediately appealing in its perceived quality, and a relief, really; they don't call undue attention to themselves, and instead "channels" the music in quite a natural way. 

I usually favor a higher efficiency segment of speakers (also actively configured), but in a no more than a moderately sized listening room the Grimm's are a treat. My sonic preference could be described as a "musical monitor" sound of sorts, and I'd say they comply with that sonic DNA - for whatever it's worth.
