And the subwoofer has a piezo accelerometer for the digital motion feedback.The woofer is a Seas Excel W22. The tweeter a Seas 27 DXT (H1499).
The subwoofer is 10". It looks much like a Dayton RSS series driver. But could be something else.

Yes, which could be attached quite easily to an off-the-shelf driver that doesn't have one.And the subwoofer has a piezo accelerometer for the digital motion feedback.
Yeah, it was the only logical reason I could see for that kind of a roll off. It does make the bass distortion measurements look better than they really are though here in this review, because the bass is just not on the same level of other speakers that are flat down to their more aggressive roll off point. So if you were being fair you'd bump up the response of the subwoofer part to be more anechoic flat and the distortion measurement of the bass under those settings would then be more comparable to other reviewed speakers in my eyes. I'm therefore thinking we shouldn't get too excited about how this speaker/sub measures for distortion in the bass.KEF does something similar in many of its speakers to account for room gain. A strategic move to maybe help users get reasonably flat bass without EQ.
Well in that case I take back part of what I said earlier in this post, as it seems it's designed not to play low and would indeed need a sub to be paired with it anyway if you wanted to play low. But still, my point about the amount of measured distortion of the bass holds true - the bass is rolling off from 100Hz so is at a lower level than many other speakers tested so the bass distortion measurements still look better than what they really are, so to speak, if compared to other speakers that attempt linear bass extension. The fact this expensive speaker kind of needs a sub makes it a bit more of a mockery, to use a cruel word, but it's super expensive, so.No. The "subwoofer" in this speaker is not a traditional sub. It is a component that becomes part of the speaker, taking it from 2-way to 3-way. Indeed, that is how you configure it in the software. As such, I tested it like any other full range speaker. In the case of the measurements, the speaker is 5 foot above the floor so even near-field, non-anechoic response is going to show response that is closer to anechoic than otherwise. Also, in that near-field graph, I adjust the height of each driver. They actual levels are not correct. They are just a guess on my part (in this case, matching them to the crossover frequencies).
To the extent we test all speakers with deep bass response the same way, they can all be compared the same way. This is the purpose of testing. To take out the environmental effects.
The thing to pay attention to here is the integration of so called 'sub' with the rest of the speaker system. This is what GRIMM is bringing to the table which you would not have with a stand-alone sub.
Finally, I listened to the speaker and noted in the review that deep sub-bass is not there as there is in other full range speakers. What it plays is exceptionally clean but it is at higher bass frequencies.

This driver could be something different. But that's what it looks like to me.
Well, probably because it is not.does not sound easy to me?
Attaching the sensor is easy. Doing all the rest of the implementation is where the work is. Obviously.does not sound easy to me?

I don't really agree, the bass is what it is (apparently not very strong) but the distortion is a reflection of what you would actually hear in use. "How much distortion would this speaker have if you EQ'd it" would make it harder to compare different speakers.if you were being fair you'd bump up the response of the subwoofer part to be more anechoic flat and the distortion measurement of the bass under those settings would then be more comparable to other reviewed speakers in my eyes.

I know that most piano pieces don't use the lowest note, but the point stands that there is potential information, and often information, in the low end of bass for all genres. At least that's what my spectrum reader says.Ugh, I dislike when this talking point is brought up. As someone who plays piano, I can assure you that most piano repertoire does not use the lowest A. Further, the bass strings for the lowest notes on all but the largest of concert pianos have so much harmonics that you hear those more than the fundamental.
Still, at this price point I don't think it's unreasonable to expect this speaker to be able to cover down to 20Hz competently considering there is vastly cheaper equipment that can do so.
The room, the floor especially, will alter the output dramatically. It will lift the bass output, without increasing distortion.Also, I'm not 100% sure the distortion measurements would get worse if you EQ'd this thing.
Our DIY buddies could simulate the outcome of a variety of possibilities. I would opt for a 8" bass, a 6" midrange, and a 1" tweeter a la DXT x/over at 1200Hz to at least gradually mitigate the problem with vertical lobing.I have lusted after this speaker for years. Reading the white paper ...
It's about half the volume, what do you expect?Why does the sub perform so poorly? The KH750 is almost a tenth the price, also uses a 10" driver, but extends down to 22Hz at -3dB and has tons of fancy DSP features.
I should add that a great way to tell is to put in filters on the sub, which is easy with certain SVS subs and the app. If I put a 24db filter to cut 40 hz down, I notice a difference in a lot of music. At 60hz it's a big difference. At 80hz it's a huge difference in pretty much everything. This holds true when the sub level is matched by ear but also when it's matched by Dirac.I know that most piano pieces don't use the lowest note, but the point stands that there is potential information, and often information, in the low end of bass for all genres.
