I used to own them as I bought them new much cheaper than their alu enclosure siblings the 8040, indeed very good loudspeakers and I even liked their looks more. Many people said they were discontinued (same as their 5" M030 counterpart) because they didn't sell well, possibly as they were marketed as kind of cheaper online creator content monitors which is a pity. The enclosure was made from recycled fibres and even the packaging was fully recyclable.Wonderful review! Wonderful speaker! Why did they discontinue manufacturing it?

This is a review, and detailed measurements of the Genelec M040 powered studio monitor (active speaker). It is on kind loan from a member. It has been discontinued but cost US $895. I see a few available still for $600.

I like the more traditional look of these speakers. They have their curves but not as pronounced as the current series. Back panel shows the usual connections:
View attachment 224405
I misread the labels and measured it first with -2 dB bass. Had to do it over again. Power connection is a figure-8 cable which is easier to plug into the back than larger traditional IEC. It was nice to see RCA input as well.
Speaker feels very solid but not overly heavy for its size.

Genelec M040 Measurements
Let's start with our usual dashboard of frequency response and directivity:
View attachment 224406
Overall response is quite good. The only exceptions are a peak due to cabinet/port resonance around 650 Hz. And bass level being somewhat shy of treble. Here is the near-field response to show the former:
View attachment 224407
The resonance is very clear. On the other hand, the woofer response is impressively smooth out of band.
Early reflection shows what we already know about the resonance:
View attachment 224408
Combining with sound power, we get our predicted in-room response in far-field listening:
View attachment 224409
Horizontal beam width shows the nice control in that axis:
View attachment 224410
Ditto for our contour plot:
View attachment 224411
Typical 2-way design shows the usual two "eyes" in the vertical domain:
View attachment 224413
Distortion is impressively low at 86 dBSPL. It was also just as clean at 96 but clipping light came on toward the end and levels lowered:
View attachment 224414
View attachment 224415
I lowered levels to 90 dB and while the clipping light still came on, there was no limiting:
View attachment 224416
Notice how the left side hugs the near 0% distortion line where our hearing is most sensitive (2 to 5 kHz).
Waterfall basically highlights what we know about the port/cabinet resonance:

Genelec M040 Listening Tests and Equalization
I listened to the M040 monitor in my near-field setup. Without EQ, the overall sound was good but it was not until I applied EQ that I realized more bass was better:
View attachment 224419
The small notch filter for the port/cabinet resonance as usual improves clarity (although it is very subtle). Once there, the M040 was a delight to listen to. While there is no sub-bass to speak of, the rest of the spectrum sounds wonderful. I especially liked male vocals with the above EQ applied.
I am usually able to clip smaller Genelec speakers but could not do so with the M040. No matter how loud I made it, the clipping indicator did not come on and I could not hear any distortion.
I don't know why but I went into this review thinking the older generation Genelecs don't perform. But I was wrong. Other than one port resonance and small matter of bass output, performance is classic Genelec: great attention to design, construction and overall fidelity. With two simple filters, sound reaches upper echelons of performance ladder. With their more traditional look, the M040 could even be a better fit than some of the newer generation!
I am going to recommend the Genelec M040. With EQ, my recommendation goes up as some of the best bookshelf speakers out there.
As always, questions, comments, recommendations, etc. are welcome.

I strongly vote YES to reviewing older products!
First, it is a valuable data point and other, maybe more important aspect, is that there is a used market to think of!
That used market is very big in some undeveloped parts of the world.
Yes It looks like it.Are they using the same drivers as the 8040?
This is not true. Its the opposite.In my experience, the older Genelecs have considerably more power on tap than newer ones. Why this is, I couldn't tell you.
There is an S&R review. The biggest problem with the 8351A is it has a first gen Ones woofer design that had very poor output at some frequencies, particularly the dip at 40-70hz where it performs comparably to the later generation and much smaller 8331a.I'd personnaly like to see how the 8351A measures and compares to the B version you already tested.
One of the reasons I had bought them was also that the directivity was smoother than on its more expensive 8040B sibling:Here are the official Genelec measurements which as always match the NFS ones well:
View attachment 224513
48 Hz - 20 kHz (± 3 dB)
Low cutoff -6dB
High cutoff -6dB
Short term max SPL
Maximum sound output (Short term sine wave output on axis in half space, averaged 100-3000 Hz at 1 m).
Here an interesting Audio Express article about them https://assets.ctfassets.net/4zjnzn...0f90edc089/2014_anet_audioxpress_magazine.pdf
Also Sound & Recording had measured them (the main reason I had bought them) but the review unfortunately isn't online anymore.
