I mean, essentially it's saying MLs have some issues that perhaps I don't like in a hardcore devotees site! And - it's coming from a long time hardcore devotee!
Of course, "it can't be the speakers - it must be something else", if you catch my drift.
Justin, please give us a little more credit than that. I and many others on the site have no problem acknowledging defects in ML's when we hear them.
I see how you’ve read that, Rich – it wasn’t meant to be discrediting, but I see your point 100%. But I do believe there’s a grain of truth in it, no?
Yes, this is a fan site. But we aren't blind (or deaf). Yet you are proposing an issue that I have never heard or heard as a problem from other ML speaker owners, or from any reviewer, and quite honestly, the logic you are using does not appear to be based on any physical reality.
Hey hold on – read some of the other posts: danman, Beakman, JFM etc... aren’t they agreeing – at least partially in some cases?
You have yet to accurately describe what frequency band you are referring to, how the mass of the driver contributes to the perceived "weight" of the sound, or why you perceive this problem with ML's but not other electrostatic speakers (or why it is just a problem on some recordings but not others).
It is pretty obvious that I am having a go at the ESL panel – at least in the ML hybrids I have heard. But I did say, and I have said on many occasions, why I think the Quads sound much more laid back. They have a dust cover and a fabric grill to fight through – and that does mute detail – at any frequency. I have always removed covers on my speakers, including the Ascent cone covers.
I have also quoted references to Hi-FI News’s findings and Stereophile’s, suggesting that another possible cause is the frequency break up measured by Hi-Fi News. What else am I supposed to do, write a dissertation on it?
As regards to specific frequencies, it’s difficult to be specific. But I always hear said “thinness” coming from the panel.
And honestly, you seem to have a tendency to spout off whatever comes off the top of your head without putting a whole lot of thought and reasoning into what you say. If you didn't contradict yourself so much, and provided an explanation based a little more on real science and a little less on your own off-the-wall untested hypotheses, it would add a lot of credibility to your argument.
But is that what I am really doing Rich? Or am I playing with ideas, trying to gain insight and attempting to find out what others think? I’d like to think my presentation was more along the lines of “I think this is right, in fact, I’m pretty damn sure it is, but hold on, I might be wrong – what about this?” Obviously, you’re not taking it that way. I do try to write and put my points as well as I possibly can, and am always editing my posts in an attempt to do so.
If challenged, though, I will stick up for what I believe until you can prove to me beyond doubt that I am wrong – or at least agree it can’t be proven either way.

So you are saying driver overshoot of dynamic drivers prevents this issue. Which is exactly what I said about you possibly not liking the accuracy of ML's and perhaps preferring the less accurate sound of a cone driver (at least in this one respect).
Pretty much along those lines, Rich. I do believe most cone drivers don’t exhibit the problem – but some metal driver’s I have heard can display a thin quality – prime example – Acoustic Energy AE1 from quite a while ago. Also, some dome tweeters can make a real mess of things.
Any particular reason you totally ignore my point about hybrid ML's using cone drivers for the majority of the frequency range for which the CLX uses an electrostatic driver? The same part of the frequency spectrum that most people think adds "weight" to music?
Not much, apart from the fact I have been at work, and as I said, I can’t answer you all. Rich, while I value your posts a lot, which is why I am giving you so much time in this response, there are others around!
This is potentially a good point. Has ML published the exact upper limit cut off of the dual force driver? We know it rolls off steeply around 60 odd Hertz...
Another point, the CLX also uses a single film driver too. But the merger of the two seems to provide it with weight and finesse. Note, I didn’t hear the CLX with a sub – so no “weight” coming from there. But as my CLX recordings showed, and from which I posted TFFTs to show, there was low frequency grunge coming from other rooms.
Also, although the CLX uses a dual-diaphragm bass driver, which may have twice the weight of a single-diaphragm ESL driver, the actual weight of the driver mass is still virtually nothing compared to a cone driver. I can assure you that the CLX driver does not suffer from overshoot. Which pretty well shoots down this theory since you say the CLX does not suffer from this problem due to its "greater mass." You have provided no logical reason why a dual-driver ESL panel can provide more "weight" to the music over the cone speaker in a hybrid ESL like the Summit or Ascent. I promise you that it has nothing to do with driver mass or overshoot.
Rich – it has a load of air in between the film – so it’s at least twice as heavy overall plus the mass of the air it has to move back and forth. So, no, I don’t agree here.
With maximum respect to JonFo, no room treatment can stop this fundamental nature of the ESL driver.
Unless, of course, you are wrong and the problem is not the ESL driver, but the speaker's interaction with your room. Again, you completely ignored my question about whether you have done any frequency response testing in your room to see if you have a suckout of some sort that is causing this issue. But why would you want to take accurate scientific measurements? Since you are never wrong, what possible good could come from gathering data about your room's frequency response?
Now that is just the lowest of the low there... what a load of tosh!!! Of course I can be wrong. I dunno whether you got that off Jeff’s comment, and yeah sure, we have disagreed on some issues, but I think Jeff and I are both pretty strong minded people, so it’s not surprising. I think I won a few of those disputes. Jeff won’t agree to it – but hey – that’s human nature and pride kicking in on both sides, I guess. And whilst I’m sure I was right, there is of course the possibility I wasn’t – if you catch my drift. Haven’t you ever been convinced you were right about something – only to find out you weren’t?
What is weird is I have never heard it in Quad 2905s, ESL63s or 57s - but they all use grills that I think removes detail and "softens" the sound.
But wait, didn't you just say above that this problem was the "fundamental nature of the ESL driver?" You seem to contradict yourself every other sentence. You say the CLX doesn't exhibit this problem because of the mass of its double layer bass driver, while ignoring that hybrids use a cone driver for the majority of this same frequency spectrum. You say the issue is "fundamental to the nature of the ESL driver" but then say it is only a problem on some recordings and that you don't hear it with Quads. You say no room treatment can solve this issue, but then say that the Quads don't exhibit the issue because the grill covers "softens" the sound. (By the way, grill covers would have absolutely NO effect in the frequency band which you are talking about. They may soften the highs, but would have no effect in the lower midrange).
Provide some scientific proof for this one (your grill theory) and even then I’d find it hard to swallow. But it would add weight to your argument.
You say it may be because of a frequency breakup measured by hi fi news, and yet in another thread you go on about how much Ken Kessler loves the Spire and the Summit. Did Kessler mention anything about midbass thinness in any of his reviews? Seems like a professional reviewer would notice and want to mention a lack of weight in the midband. You may very well believe that you are right. But you sure aren't making a very good case to convince anyone else.
No, Rich, but as I have indicated, some here seem to be in agreement – read the other posts. I don’t think Ken did say anything. But then you yourself have stated how little reviews mean to you, in no uncertain terms. The Spire review is online, though, together with the frequency response and waterfall plots.
Finally, since you have ignored the question twice now, I will just have to assume that you haven't tried biamping your Ascents. I propose that biamping your Ascents properly, combined with some good acoustic treatments in your room, will do more for your sound than any other upgrade you could make to your system.
No, I haven’t tried bi-amping my Ascents. Nor do I feel the need to – very happy with the bass and the Descent – as I have already said.
As I have said quite a few times, the walls in my room are plasterboard, with insulation behind it. It is the “deadest” room my MLs have ever lived in by far. But yes, you are right, I have never tried any “real” treatments. But I have hung three towels against the wall (trying to see what the effect of actually spending money might have) and not liked the results. I like some rear wave reflection – it does add space and air to the sound.
Please note that I am not trying to convince you not to experiment with other speakers. Part of the fun of this hobby is experimenting with all kinds of technologies to find the right combination that works for you. All kinds of speaker drivers have their advantages and disadvantages. I just think that ESL's require a lot more work to set up properly to get the most out of what they are capable of, and I suspect that you are poo-pooing some of that advice and not realizing the full potential of your Ascents.
Rich – I have dearly loved them for years. Massively so – but those Apogees are definitely on the way. I will keep you posted!
After all that, I truly hope at least some of your “issues” have been resolved.
All the best,
Justin
