No filters, no DSP no nuttin here.
But limiter, compressor ?
Thanks for the details, much appreciated! But I think the price is too steep for me.I’m the owner. I have a pair as Atmos speakers as middle height, and I got a second pair to add some front heights.
For sure. It’s a luxury item from the standpoint of paying a lot for made in California, the reputation/brand markup, serviceability, and trading off size for performance. It’s also weather resistant and rated for outdoor use and you can even get full weather protected versions.Thanks for the details, much appreciated! But I think the price is too steep for me.

But it is neat to see real measurements of a purpose-built exotic speaker like this. It’s literally the limit of what a single 4” full range driver can do. You could more correction of the FR in DSP, but because it’s intended for supporting live music, they are much more sensitive to processing delay compared to home speakers.
One thing is for sure though. None of the Meyer Sound speakers score super high on the standard preference score, and yet in real applications, they sound pretty amazing. I think most audiophiles going to a live Cirque du Soleil or Broadway Musical come away with the impression that things sound great.
It was some of these experiences that got me interested in the company, which led me to the Meyer Sound Amie and then building out a home theater with other Meyer Sound speakers. For these 48V speakers, I get a 1U rack power supply that handles 8 channels, which is nice compared to a 8 channel Buckeye or HypeX amp.
What’s great is that the measurements are the objective truth, and the subjective experience is still just the subjective experience.
Perhaps at some point you get to the performance level where variations in frequency response are no longer that big of a deal since it’s good enough to be masked in stereo? Is it group delay? Phase? IMD?
It also could be as simple as circle of confusion since a lot of my reference “gold standard” experiences are musicals or concerts that use live stage reinforcement, often with Meyer Sound gear.
But i guess for large venues there’s are other sources of information I don’t know about it seems to be it’s own field of research.
Sounds in large venues is better than ever .
Taking a quick look at the PCB, PWM 7 and 8 are not connected, PWM 4 goes to test pads, PWM 1 and 3 go somewhere, and on 2, only the P side goes to a test pad. It's safe to say that not all channels are being usedOk thx to be honest i have no idear what a 8 channel PWM modulater does in a mono speaker but hehe i would also not know in a 8 channel speaker.![]()

It's safe to say that not all channels are being usedIt's a curious choice for such a product for sure, but I guess It contains just enough DSP features to make it work, and they may reuse this product in a whole range of other products. The chip can do dynamic range compression, giving it a kind of limiter option, seven bi-quads per channel, additional tone controls, and low/high-pass filters.
These are all just headers on the evaluation board. What is the relevance here?
I think we are in quite a lot of danger on straying off topic for a speaker review thread . Let's not go further into the weeds please .
But this is the DSP in this active speaker, so it seems on-topic?I think we are in quite a lot of danger on straying off topic for a speaker review thread . Let's not go further into the weeds please .
Yes, but not posting random headers of some eval board of the PWM chip that happens to be used by the speakerBut this is the DSP in this active speaker, so it seems on-topic?
I compared the ASR measurement with the data provided by Meyer Sound: NFS is oscillating a lot less below 400Hz but overall that's close.

Yes, reading/posting diagrams early morning after hard night is no-no. My bad.Yes, but not posting random headers of some eval board of the PWM chip that happens to be used by the speaker![]()
Coming a bit late to the party... Thanks Amir for this thorough exploration of such an odd duck speaker.This is a review, listening tests, EQ and detailed measurements of the Meyer Sound MM-4XP, active "micro" monitor (4 inches). It is on kind loan from a member and costs US $1,180 plus the cost of external power supply.
These speakers are not meant to be a general purpose speaker to be used in your typical noncommercial application. What they do offer is reasonably high quality audio performance when used appropriately, and they will do it day in and day our for many, many years, and best of all, if they fail Meyer will repair them at a reasonable cost.Not much there for $1180 each.
