Grandinote Mach 8 XL vs Mach 9 speakers

Yes you have, see posts #73 and #74 and you even commented on #73. They both have quite good bass.

Ok, with audion etc. I will listen again later don't remember now but I think I liked the videos that Abeidrov was later sharing with the Jadis - Grandinote - Gryphon. It was sounding like a decent set up one can listen various music on.
 
2018 the best sound of the show volta dac, shinai amp + mach 9

P.S grandinote shinai with soundkaos same league

Btw, your Gryphon does play the Rabin better than the Jadis and the Grandinote amp on my earphones, will listen on soundbox later.
No, it does not. Please, listen to the tone of violin with Mephisto. It’s shouty and lacks body compared to the own Grandinote amp.

Again, this is not the type of music I am talking about. Just one or two instruments. I tried Mahler 5th and Beethoven 9th and 7th. The results were the same. To quote one experienced audiophile, who was visiting me at the time: “Mahler sounds more convincing with WA speakers.”
 
As I demonstrated with other videos, as well hearing them live, the speakers can produce outstanding bass. Why they don’t apparently in Abeidrovs’s room probably has to do with his room, not the speakers. Your analysis disregards these facts.
The room doesn't affect break - in and sure the room can and will have an influence on bass output at the listening spot. But it doesn't change my statement above, it's physics.
 
It is very easy to create more bass, disregarding quality of sound.
Yes, add subs. For quality, integrate well and employ high - quality subwoofers. You can also move your speakers and sweet spot and even room treatment can help sometimes.

Ok as I said I will listen on soundbox later I am at work so only heard on earphones. Compared to Jadis it has more nuance and dynamic range. My earphones are not best for playback

Just by putting bigger woofers and bigger boxes and not having coherence with top you can get more bass. FYI he is not referring to subs with either speaker

If you are looking for a more dynamic, bigger soundstage and more thrilling musicality from a speaker, then listen to Analog Domain Argus. That speaker does impressive every time i listen to it.

We're talking passed each other. He's talking about his speakers in this post, there is no option to expand the cabinets, etc.

Also, yes, I mentioned subs as a way for more bass with the same speakers.

Just heard at home, the Grandinote is much better.

Woofers commonly require minimal break - in time. And as the owner noted, Wilsons as with most more conventional designs (3 - way) with dedicated bass drivers versus drivers that are closer to full range covering midrange frequencies rarely deliver such a large frequency range effectively. That's why very, very few designers employ such an approach. For them to be effective, it might make sense to roll them off at ~80Hz and add subwoofers to cover the bottom 1.5 octaves.
The Grandinote design is quite different from Wilson’s. It relies on a mechanical crossover and specific damping structures behind the driver membranes, which naturally makes the break-in process longer. These physical elements take more time to loosen up and reach their optimal behavior, so the sound, especially in the low frequencies, keeps evolving with hours of use.

Compared to Wilson, which may need around 50 to 100 hours of break-in, a mechanically crossed design like the Grandinote can take roughly two to three times longer. The damping materials and suspension system need more time to fully settle, so it can easily reach 200 to 300 hours before the performance truly stabilizes.

I think that observation might apply more to single-driver full-range designs such as the Cube Audio Nenuphar rather than the Grandinote Mach 8 XL. The Mach 8 XL uses eight 6.5-inch drivers working with a mechanical crossover principle, providing more than twice the total woofer surface area of the Wilson Sasha DAW. With that much radiating area and its high efficiency, it can deliver large-scale orchestral works like Mahler or Beethoven with greater ease and scale once properly broken in. It’s not a typical full-range limitation scenario, it’s a different design philosophy altogether.

You keep omitting the fact that each 6.5" driver is required to reproduce not your typical 2-3 octaves but everything <=~5KHz, over 7 octaves, a tall order for any driver, even 8. So the Mach 8 XL doesn't have woofers per se, it has essentially 8 full - range drivers and a tweeter covering ~1.5 octaves only. That puts an enormous burden on the drivers.

Also, driver size alone doesn't account for LF dynamics, Xmax matters much. That's why in the Enjoy the Music review, the reviewer states, "The only spec I would question is the 20Hz extension, although I would assume that's 20Hz (-4 or -6dB), so who knows for sure? I do know that I did not get the base extension I had in my room with the Wilson Alexia 2" which the Sasha DAW uses the same woofers if I recall (albeit a slightly smaller cabinet).

That's why I mentioned either rolling this speaker off at ~80Hz or complimenting at full range via adding 2 subs would provide a completely bigger, better experience.

Sasha DAW also doesn’t get down that deep being -5dB already at 40 Hz.

I think we are seeing a long break in effect because the 8XL can clearly go deep bases on other recordings and my own live experience with them. Some stuff high sensitivity drivers can take 1000 or more hours.

Not correct driver fs and port tuning always results in -3db point between the two impedance peaks.~27hz20251105_223037.jpg
P.S
Wilson always uses bass reflex ports to create deep bass in the room. Whether you like that or not is another matter.

The Mach 8 XL’s concept is not about forcing each driver to behave as a true full range unit. The eight 6.5 inch drivers are mechanically tuned and acoustically loaded in such a way that their effective bandwidth is naturally shaped by damping and enclosure interaction, creating a smooth mechanical transition rather than a traditional electrical crossover. This approach spreads the workload progressively across the array, so each driver operates well within its optimal range instead of covering the entire 7 octave span equally. In practice, the upper drivers tend to contribute more to the midrange, while the lower ones handle more of the low mid and bass energy, creating a natural and gradual frequency distribution across the array. And regarding Xmax, while each individual driver may not have extreme excursion, the combined displacement of eight cones results in a very large total volume of air moved, providing strong, fast, and well controlled bass without relying on long throw woofers.

Regarding bass extension, the 20 Hz figure in the specs is indeed likely around −4 to −6 dB, but that’s still comfortably within the range needed for large scale orchestral works. In classical symphonies like Mahler or Beethoven, there are virtually no musical notes below 30 to 35 Hz. Frequencies under 30 Hz occur mainly in church organ pieces or film soundtracks, not in traditional orchestral repertoire.

For an orchestra to sound natural and powerful, what really matters is balance, control, and linearity between roughly 40 and 200 Hz. That’s where most of the fundamental energy and perceived dynamics of the orchestra reside. If the bass in this range is clean, fast, and well controlled, the sense of scale and weight comes through fully even without true 20 Hz extension.

Subwoofers could certainly extend the bottom octave, but that’s a matter of taste rather than necessity. The design’s philosophy emphasizes coherence, speed, and phase purity over sheer subsonic reach, a different but equally valid approach.

Look at the response curve a bit further down the page and you will see where my comments come from. Sure with room gain it gets deeper but it is not going that deep on its own with any high output.

Well, you shouldn't expect miracles from an 8" woofer. fs ~ 40Hz is perfectly fine. With a clever housing and bass reflex calculations, you can even get ~27Hz. Whether it makes sense to operate well below fs of driver is something everyone has to decide for themselves. On the other hand, how often do you hear 27Hz and lower tones in music?

P.S
I would listen to the Argus speaker; it's in a different league when it comes to drivers, and the sensitivity is significantly higher.Screenshot_20251105-165328_Write on PDF.jpg
