Pure Low GR -- Infrasonic Panel

[treitz3]

Symbolico...I believe it is the, "Make us stronger" track. Now, this is off of memory, so please forgive me if I am incorrect. Great track!

What's that tune please? It does sound phenomenal.

Just listened to your clip…sounds phenomenal. Would have to go back to compare properly. From memory…the perceived space and separation in treble is better. Despite how hard hitting the bass is…and I know this track…your system positively IS massively hard hitting…I “remembered?” Your earlier recording being ever so slightly more? But truly ever so slightly.

Right after the words about “rain falling taking away the sun” in your other video I thought I recalled the metronomic beat being harder hitting than here but a smidgen.

While not subsonic, I wonder if (if my memory is even correct) the Torus or your setup was doing something down below that this beat was calling for…which is slightly different than how the PureLow is doing it?

I felt like this new version is more cleaned up, the other weightier but perhaps less clean?

But we are taking top single digit percentile performance for this track. 99% percentile either way! Enjoy and thanks for taking the recording…will go back to find the other one.

Hi Todd,

Went back to listen to the earlier recording from your system of this identical track. It was not difficult once hearing it (after several months) next to the new recording with the PureLows now in place.

Overall, your new recording wins. The new with PureLow has even more detail, completely natural…upset as well as bottom end punch.

I also think my recollection of greater slam on original is because the newer ones gives naturalness and clarity to the upper registers which raises the balancing point of the system slightly.

Bass whack to bass whack the systems sound remarkably the same in the bass. Fantastic!

Lloyd, thank you. I appreciate the kind comments. It is nice to know that some of the bass information is coming through on the video. However, there is just now way the video can convey the sense of pure power that exists. Just so you are aware, the other video I recorded of this song over a year ago did not have the Torus.

I will start working on the integration with the Trio directly in a week or two. It will be interesting as I will be able to toggle between Spacehorn only, Pure Low Only and Spacehorn + Purelow.

I must admit these sound very intriguing - would be very interesting to hear these matched to a set of panel speakers such as Diptyque or the smaller Alsyvox. If they match well, it would make a much better value proposition than the larger Alsyvox etc.

They were originally designed to mate with the Quad ESLs. So matching it with any panel speaker should not be a problem at all. The Pure Low are relatively easy to integrate as far as subwoofers go but you still have to do the work.

 

[heihei]

I don't mind doing the work - I've spent many hours tuning in my Torus using miniDSP and some class-D amps to much better effect than the WB Torus amps!

Sorry, I did not mean you still have to do the work. I am certain you have and will. It was more the universal "you". There are some who seem to think all of this stuff is just plug and play. No matter how good a speaker or subwoofer is there is still the necessary due diligence.

Wow...that sounds like an amazing next chapter in this. Very much look forward to that one! From a consumer standpoint, I think we have covered this, but because it is important and I suspect more people are starting to follow this one...what do you make of risk of repairs...as well as the number of repair people who could fix this?

A cone sub is probably straightforward...particularly a passive one. Less likely to break and there are many, many more people who can fix it. A panel by contrast is a more unique tech, with fewer people who can fix (and presumably far fewer parts available)...plus it is about whether one can find someone locally who can without having to ship it back to the manufacturer.

Your guidance on how you think about the PureLow in this more practical regard for a prospective owner is appreciated.

Hello Lloyd,

I am not sure why you think that the Pure Low would be subject to "break down" more so than any other subwoofer. Is there something specific about it you are concerned with? If there is I can try and get you information on that specifically.

Here is some detail on the reliability of the Pure Low.

First, the most obvious thing is that the number 1 thing that breaks in most subwoofers is the plate amp. The Pure Low is passive so you are free to choose any amp. (I chose the Atmasphere Class D) These external amps are going to be much higher quality than the cheap plate amp that is attached to most subwoofers. So this is not a problem with Pure Low. Probably the number 2 thing on most subwoofers is the foam/rubber surround degrades or cracks. The Pure Low doesn't have a surround like this. This can't happen with a Pure Low.

The warranty is 3 years. No Pure Low has broken down going back to the original unit produced in 2006. In the event something happened, all of the parts are field replaceable. The Pure Low is not made like a Magnapan or Martin Logan. It is not possible to "burn" it with too much current. The only real way for it to not work is a major accident. Such as submerging it in a swimming pool. Or taking a stick and trying to poke it through the membrane. Or dumping a bunch of iron filings into the magnets. Or taking a cutter and slashing the membrane.

I hope this helps. If not then please try to be more specific with your concern.

Thank you and very helpful. This was only a generalized question from the standpoint of the following context:
- the bigger the unit, the more trouble repairs are because you have to carry it or ship it
- the more rare the unit, the more you rely on the manufacturer...rather than a local pick up by the local dealer (who in our case provides a loaner unit of some kind to keep up us going during repair)
- plus, I have seen cone speakers and horns speakers decades old..the surrounds can re done by 'almost anybody who is a decent audio tech'...whereas my read of older panels is that one may need to find a specialist who gets involved in finding parts that fit or match the film materials in the original panel which are less commonplace than finding another 18" cone, etc, etc.

That is all. Sounds like 'it is what it is'...and if you find them robust in your use of them, that is a great start.

Okay, I think your concern is not that it will break but if it does break then how are you going to get it fixed.

There are no obscure parts used to make a Pure Low. Patrick would support the product if parts are needed. But let's say in 20 years something happens. If you hand it to a competant technician they will see what to do and would be able to find the parts.

Thank you and helpful. As I see on their website PureLow appears to be part of a larger French company, is that correct?

Hello from France !

I'm Cédric, and sorry for my English....it's an English from my school, and it's a long time ago....I've two Pure Low since 4 years, and a friend since 10 years. We listen music all days, at a good volume....sorry for my wife...We never have a problem with the Pure Low, it s a hard construction (I dream of that level in other manufacturer). All it s fabric with the hand, no machine, and industry.
My friend moved 3 times, and no soucy.

I'm Ok with a last message, there's no electronic in the Pure Low, it's not Quad, Martin Logan, Magnepan or other. It's different....and if I can help you, make me a promess, no listen the Pure Low....because after, you dream of that, you think Pure Low all the day...You want one...when I've listen the first time I've take a foot "in my ass", sorry, but it's that...It's a very new thing in the world of hifi, not a marketing dream...

For information : I use that with Quad esl57, and Triangle Magellan concerto.

Merci beaucoup! Il y a au moins 30 annees que j'ai pris des cours en francais au lycee! Pardonnez moi pour mon terrible francais! Merci encore pour votre message. Excellent hautparleurs!

Est-ce que c'est possible pour vous decriver la difference entre hautparleurs typique (caissons de basse) et le PureLow? particulierement la qualite du basse et son? Vitesse? Details? Et aussi, le pouvoir sans effort? Moi, je cherche pouvoir sans effort parce qu'il cree un ambience, sens du l'espace incroyable. Oui, c'est formidable en voyant les films aussi...mais, je cherche pouvoire sans effort pour l'ambience total.

Merci bien...et si vous preferrez reponder en anglais, je vous remericier an avance! Mon francais est vraiment terrible et c'est difficile pour m'ecrire et lire!

Hi LL21, excellent your french, I hope the same english....for more precision and comprehension, I prefer use google traduction for my respons.

In my opinion we are comparing 2 incomparable things, basically it is made to do the same, but neither the way nor the result is comparable. I tested a lot of things to get bass, a duo of 38cm Audax, different subwoofers, but in fact on classic speakers, I have the impression of listening to their faults: it drags, it's noisy , that does not correspond to reality. With the Pure Low, "you don't hear it", it doesn't bother you, it's as fast as an electrostatic speaker, so it fits with it, doesn't lag.
With the Quad esl57, it becomes one. No one can tell me anymore that I don't have enough bass with my electrostatics...it's much more beautiful than my old Martin Logans, we don't have this boom boom which doesn't bring any musical information...just bad feelings. At the same volume as before, I have more treble, midrange, of course bass, but coherent, which gives fullness, more detail. As a result, you improve all areas: 3d image, presence. You can use it for hi-fi, listening to or watching live shows, home cinema. I find it easy to use, no need for a big amp, it works with a class D for me, with an analog filter. I also had excellent results with a digital filter.
I started listening to music that I didn't listen to before: classical, organ, etc...

Merci mille fois! Tres tres clair. pour la premiere fois, je pense serieusement de PureLow! La vitesse extreme comme pouvoir est tres interessant. Aussi l’abilite d’utiliser le PureLow avec vos hautparleurs sans beaucoup de travaille.

Hello, I hope some news of you and the Pure Low ? I'm very impatient to have your feeling !

Hello, I hope some news of you and the Pure Low ? I'm very impatient to have your feeling !

The Pure Low is fantastic. I have no complaints and only exuberance. I am still using it crossed over at 30Hz. It integrates perfectly with the "Spacehorn". I had someone over last weekend and we did some A/B testing. I was initially playing some music with really low bass which pressurizes the room like nothing else. But he wanted to see what the Pure Low did with just some simple vocals. It easily perfromed the spatial magic trick. Suddenly there was space around the singer and she had an actual body. Pretty phenominal stuff.

I have started the journey of integrating the Pure Low directly with the Trio. But the first hurdle I have to get over is the learning curve of the Danville DSP. I built my model and got it connected but I have no sound form the Pure Low for some reason. I had to submit an email to the Danville Help Desk. Hopefully more to come soon.
