Due to lots of interest I thought I get out this write up of the Martin Logan Neolith at CES 2016 in its own separate thread.

As you read this, please note that I am not a professional reviewer and in the past have posted critical view of a different model of Martin Logan. In other words, everything I say may very well be wrong :).

And please excuse the poor color balance and quality of these images. Just no time to post process them before running to the show this morning.

The presentation was a joint one of Constellation Audio and Martin Logan. This is a front of view of the small room it was in:

I was surprised as I expected it to be one the many larger suites on those upper floors.

When I got there, the front row was already taken with a gentleman that had come with his own bag of LPs and was getting extreme attention from the company people. I thought he was an important dealer until he stood up to change one of the LPs and I see that it is Michael Fremer! So no wonder they were ready to shine his shoes if he so desired :D.

And shine they did as they let him play long segments of 3-4 LPs and we had no choice but to sit there and listen. Not that this was bad mind you. I could see why he had selected that set of music as they were generally very good sounding.

The first LP that was playing when I got there was the West Side Story broadway play. Unfortunately I did not take a picture of it as I could not from where I was sitting in the second row. I looked on Amazon and the covers seem different but it could also be my failing memory:

The track that was being played I think was Dance at the Jim. The presentation at first was very nice in the way the instruments were separated and "clarity" of high frequencies. But after 30 seconds or so, its brightness started to get to me. But I could see some of the things ML does right. That loudspeaker was "light on its feet" subjectively presenting an airy representation of mid to high frequency notes.

After a while the organizer asked if we wanted to listen to other types of music. All of us in the second row screamed, "YES!" Only to find out we were not being addressed but Mr. Fremer :D. Thankfully Michael had other music to help us evaluate the loudspeaker.

While the LP was being changed, I hear this loud, rumbling fan behind us. I mean this is in obnoxious category. It also smelled like artificial pine scent throughout the room. Both were highly distracting. Later as I was leaving, I discovered the culprit for one or both:

Are you kidding me? We are here to listen to high-end loudspeaker yet the noise floor and smell could not be more distracting.

While waiting for the LP change still, Michael told a story of how he had given a bad review of an "optical cartridge" and how the one and only customer of this $50,000 cartridge in US had canceled his order so he was getting grief from distributor.

Back to the music, I am sure many of you the west side story LP. Would you please advise if it is a bright recording?

The next LP we were treated to had handwritten "EC Arms Forces EP" on the inner lining. I assume that meant Elvis Costello / Elvis Costello & the Attractions Armed Forces. Again another album I do not own. This one was more soothing.

Anyway, after about 20 to 30 minutes, Michael left and so I hoped I would get to talk to the crew and play something I knew. I reached out to the person that was doing the demo and asked him if we could play some other selections. He asked sheepishly if it was "OK" to play from their digital server. I said of course. Instead of doing that, he mumbled something I could not understand and proceeds to put on the LP's of Patricia Barber and played the classic/overplayed Black Magic Moment track. And walks away!!!

Man, was that a tragedy. The LP sounded like the needle was struggling to play through a bucket of sand. Background grittiness was so high it was unbearable. The highs distorted. If it were me, I would break that LP into pieces and put it in the trash bin.

Now as it turned out, this was not such a bad thing as I heard what I could swear was resonances of the panel in one loud note. So I walk up to the speaker and put my hand on the surroundings of the panel. The amount of vibration transmitted to it was insane. At first I thought it was bass induced. So I put my hand on the box at the bottom. There was still significant vibrations there but at lower level. So clearly it was not the source.

I slid my hand on the panel surrounds and by that I mean the red part of the frame starting at the bottom going all the way to the top. The vibrations kept increasing. At the top of the panel frame, it was incredible amount. I actually thought the panel was moving back and forth. I am exaggerating but you get the idea.

In my view, this means that panel does not have sufficient structural support. It is exerting forces on that thin frame which due to being cantilevered, gets worse and worse. Every one of those vibrations acts as a dirty loudspeaker generating its own sound.

I expect a lot of money in a statement loudspeaker to go towards deadening cabinet resonances. Sadly no trace of this was here. I mean maybe it is hard to do that with the frame of the panel but what is the excuse for the bass enclosure? Note that we were listening to mid levels. Nothing loud or dynamic. No matter what note was being played, the cabinet played as an extra member of the orchestra.

While I was there, I made some other observations. If you assume the sheet of paper parallel to the front of the loudspeaker being 0 degrees, at up to 45 degrees or so, the highs are very muted and the sound not so pleasant. But all of a sudden it comes into focus and not at 90 degrees. The muted sound from side reflections will interact with the room heavily and influence the tonal quality of the loudspeaker. Likewise, the back wave sounded very different. They had absorbers there in this room by the way.

Note also that like all panel speakers I have heard, the location of sound moves with your ears.

Sit in front of the loudspeaker and then gradually stand up and the sound source travels with the location of your ear. In one of the demo tracks I heard this effect as the soundstage being too close to the floor. On a taller chair likely it would move up. The dependency was quite high so if you slouch and then sit up in your seat, expect the sound to move up and down with you.

This is another observation that hit me and again it is something I have observed with other panel loudspeakers. They have a large tendency to make everything sound like their sound. In some ways this is quite good in that if you prefer this flavor of music reproduction, most everything you play will have those qualities. But if you don't, or like me get tired of hearing of it, then it can be a deal breaker. With box speakers, when you play different music productions and types, the sound tracks their origins. It goes from sounding bad to exceptional. But with these panel loudspeakers you get a much more smoothed over presentation that is the overlay of the sound of the loudspeaker.

Anyway, I am done and ready to be stoned. :) Before that, here are the rest of the pictures:

Thanks Amir, great pictures and description. Very disappointing to read about the panel's support-structure vibrations, and it's something I was able to effectively kill in mine, don't know why ML wouldn't spend the time to fix this, at this price range. Ugh!

Was it the speaker, or the electronics. I have none of this effect, could be euphonic electronics???

Typical panel effect; in my experience, there is only one ideal height that integrates with the bass correctly.

PS: I wonder if that air sanitizer doubles as dehumidifier? What's that "60" reading on it? Looks like a desired humidity level (MLs sound dark over 65% humidity)
 
Thanks for taking the time to put this together. Your thoughts align with mine although mine are regarding the CLX. I wanted to love those big boys in the worst way because my local dealer had a pair on hand and was willing to make me a crazy good deal. He set them up in a decent room driven by Levinson amps with the source being hi res FLAC files on a server. It didn't take long for me to reach the decision not to buy. The detail was phenomenal but there was no apparent depth to the soundstage. The dealer agreed saying it reminded him of the scene from a The Wizard of Oz where he gigantic face was projected on a screen...strictly two dimensional. Before the ML diehards flame me they need to know I've owned three prs of Aerius i's and still run a pr in my HT that's on it's 2nd pr of panels. The big CLXs just didn't do it for me..

Yup, line arrays have this issue too. Not on every track, but the placement of images sometimes just doesn't work out very well.

IME, dipoles do have their own sound due to side cancellation and how the backwave is handled. Panels and ribbons also add to this with their own sound signature, they just aren't as neutral sounding as a good dynamic driver and also can't produce the impact required to sound realistic at lower frequencies. Despite those issue they have their charms and I can see how some people really like them.

Most odd indeed. No shortage of 3D soundstage in my own room with CLX's, on tracks that exhibit plenty of sound stage in the recording, especially live, you are seated within a sphere of sound with effects, manifest, from behind ones head right back to behind the transducer line.

Que the usual array of Panel Sniffy Monkey Box Lovers;)

Amir, thanks for the report and I look forward to your other CES reports. Perhaps MF was there to hear that turntable and the SAT arm which he liked so much in his system. Amir, do you know what that turntable is? I've never seen it before.

Could you also speak a little to the panel integration with the woofer? In my limited experience with Martin Logan speakers, this seems to be a critical aspect to their sound.

Here's an answer to what was going on, perhaps:

Thank you very much, Amir, for taking the time to visit that demo room and listen and post your impressions! I really appreciate it!

I do not want to think about how bad the vibrations from the frame surrounding the panel would be with the traditional ML surround made of wood and plastic (and maybe aluminum?). I would have hoped the phenolic resin structure would be extremely rigid and solid. I will perform the same test the next time I am with Neoliths.

Is that because the off-axis response is unbalanced (as we all know) and, therefore, listeners have to sit in the "sweet spot" which is way too small for a roomful of people? Or some other reason?
 
The rear wave of panels usually gets compromised big time at a show because of the room. They have either a glass window or a hastily put up cloth treatment behind them, instead of the flat wall that's recommended. What's a panel without the rear wave?

The bass is usually lost in a hifi show room

Panels usually used during a show have just been built in time for the big show, and as they are not burnt in, sound bright

The sweet spot is tough to locate and occupy at a show, and a panel is all about the sweet spot.

Takes months to get a panel toe in right, and it usually sounds crap till then.

You will really struggle to get a sense of space, soundstage, and imaging which panels do well in a hifi show room

I have to say I think that sounds a little bit like sour grapes. Every show demo situation is suboptimal and hastily put together. If bass is usually lost in a hifi show room then that would disadvantage cone speakers as well.

I know for a fact that the Ferrari Red pair of Neoliths at CES and the Meteor Grey pair of Neoliths I saw at T.H.E. Show in Irvine are the pairs that are making the rounds of the "Truth in Sound" tour around the globe, so I have to think they are burned in.

I think the most valid point is the narrow sweet spot, which guarantees that the panel speakers will sound not good to everyone except the sweet spot listener and the person or two directly in line behind his chair.

Amir was there, we were not there, and I fully respect and uphold Amir's impressions.
 
How does one adjust toe in with these curved panels? Is the center of the panel used as a reference point for a laser pointer and are they meant to be on axis with the listener or slightly toed out? I assume one listens for tonal balance just as he does with cone speakers, or is it somehow different?
 
There is an ML video on how to adjust toe in. But to get it right takes months and panels don't sound right till they sound right, the sweet spot is so narrow.

The rear wave usually is poorly done at shows

Not sour grapes because I said it before, when you asked Amir to take a look at the neolith. I said never heard a panel sound good the same panels which I later heard in a proper room

Put a light source on your nose.

Rotate the speaker so that the reflection in the panel is about 1/3 of the way across from the inner edge of the panel.

In my case, I also adjust the tilt so the reflection is from the center (vertically) of the panel, which leaves them leaning forward 3 degrees.

Imagine the panel divided into three vertical strips. ML suggests you aim the inner third of the panel at your ears and adjust to taste.
 
Peter one doesn't only listen to tonal balance but also imaging and sound stage changes massively with toe in
