Long time reader, first time writer.

There's something I've long wondered about Wilson speakers. The team at Wilson goes to great lengths and expense to put together a speaker where each driver can be infinitesimally adjusted with the goal of making sounds of different frequencies, each of which travels at a different speed, arrive at the listener's ear at the same time.

Am I right? Do I understand Wilson's design?

My question is this: Musical instruments have no such adjustments. The bow of a violin hits the strings at at one very small point in space. From that one point, sounds of all frequencies are launched. These frequencies all travel at different speeds. But one can't adjust the violin so that all of its frequencies reach the listener at the same time. The real world is not so orderly.

Does't Wilson want its speakers sound like the what we hear in the concert hall? Why would they want their speakers to sound unnatural, even if they've managed to improve on what we hear in the nature?

People have been paying six figures for Wilson speakers for many years so I'm guessing that there's an answer to my conundrum. But for the life of me, I can't figure out what it is.

Sound actually travels at a fixed rate, regardless of frequency. In air, that speed is ~1,125 ft/second (depending on temperature and humidity).

For an ideal sound source (infinitely small point), sound energy would travel in all directions at all frequencies at the same speed. For a multi-driver speaker with a frequency dividing cross-over, different frequencies are coming from the different drivers, so the idea is to correct each drivers' physical offset at the listener's ear.

Hope that helps.

So my mistake was in thinking that that different frequencies with different wavelengths travel at different speeds. In reality, "sound actually travels at a fixed rate, regardless of frequency." Seems like something I learned in high school and forgot during college.

Now that I'm comfortable with Wilson's engineering, can anyone spot me $67,500 for a pair? Do you think Wilson will feel compelled to send me a couple in appreciation for provoking this edifying discussion?

The simplest answer is a full-range single driver. Of course it won't have extended frequency range. But if you're willing to sacrifice the extreme bottom end and extreme top end, you can have perfect coherence with the magic midrange, where most music happens anyway. I have one full-range system and with a violin or a piano, the sound is palpably coherent. It's not so great for cymbals or tympani. But for a string quartet, or solo violin, it's incredible.
(PS: a mono speaker is even more coherent than a pair for stereo-- a violin originally emerges as a single signal from basically a single point, so it makes sense that a single transducer can more faithfully reproduce the signal than 6 woofers and tweeters)

I agree about having the high frequencies coming from a single source. Have you heard of OPSODIS technology? I created my own setup with a single tweeter used as a centre and I find the imaging much more stable and less fatiguing. Disagree about full range drivers being the end all be all however. Tough to get enough bandwidth for convincing performance through a single transducer

In my mind, all this time business that Wilson discusses might be grand, but why can't Wilsons do the right triangle time and phase result like a Vandersteen, or an older Thiel?

I’m still evaluating you. My question in any review is will the item reviewed play my reference albums. Something Peter McGrath has never allowed at shows.

Next what are you going to use as refence material when MQA fades away completely?

No point in noting Peter likes MQA. If you and Peter can’t tell MQA is just DSP and a couple of tweaks that is your problem not mine.

I would have sent this back with a lot of review comments. Happy Holidays, stay safe and warm.

Hi Jason,

Each month I look forward to reading your reviews. I must admit that I generally take lesser interest in the technical details of the component under review – although that is interesting – focusing instead on your choice of review music and your discussion of the listening experience. I have discovered a lot of fantastic music reading your reviews, and I always look forward to being introduced to that next gem. My hi-fi system could not be more different technically from yours. My system is tubes, paper cones, silk domes, and wood cabinets. I mostly listen to vinyl and CDs, preferring the tactile experience of physical media over streamed digital files; I use streaming mainly to discover new music. That said, we seem to have similar musical tastes. After reading each review, I queue up the review music selections on my system, sit back, close my eyes, and listen. I then compare my experience to what you have described as yours in the review. Great fun. Thanks for the great work. BTW, I am in complete agreement, Maazel’s and Battle's interpretation of Maher is “seductive.”

How lovely of you to say this, Monty. Thank you.

I think you will enjoy the music I've reviewed for the March issue. A lot, in fact. And February promises some beauties as well. If you haven't heard the recordings from Julia Bullock and the Chiaroscuro Quartet that I review in this issue, by all means do not delay.

Happy holidays,
jason

Julia Bullock's voice is a remarkable instrument. What a gift! Thanks for recommending this recording.

And here's where I differ from others, as I prefer to read about the technical aspects of such review and can do without all this stuff about their personal reference recordings. I know it all depends on how it sounds, but I don't need to know the exact details of whatever it is (which piece of music) you're listening to. Other than that, I do think all reviews are helpful in some way. Presently I'm not in the market for such a pair of speakers (at $67K) and would never contemplate Wilson Audio. But things do change... who knows?

I recognized my upgraditis addiction in my teens and now only make changes when I'm forced to (due to component failure) or when the value proposition is overwhelming (most recently Amazon Music Unlimited, Echo Link & Schiit Modi 3). So when reading this review I felt extremely sad for previous owners of the very expensive Alexia.
Why can't high end manufacturers give a new model name to each non-upgradeable version of an existing design, for the sake of the mental health of their customers?
Better still, have a renowned expert like John Atkinson, analyze and write about the changes made thru previous iterations to determine if the improvements could have been incorporated in the first design?
At the price paid it should not take five iterations to get to this level of perfection.

First, a numerical comment. This is the third iteration of Alexia. As explained in the review, "V" signifies V-material; it is not a roman numeral.

Secondly, you are asking for history to compress itself. That is not how life works. It took years to develop the new midrange and V-material that help Alexia V sound as good as it does.

Life unfolds as it unfolds, not as it "should" unfold. Understanding that will certainly help every audiophile's mental health.

On which note, Happy New Year everyone.

At the price paid, three iterations in nine years is excessive. Would you buy a speaker if the salesman told you an improved version will appear in five years? Loudspeakers are not like other consumer goods. A well designed & manufactured speaker should last decades of daily use. Is it too much to ask for a model name change (and of course price increase) at each iteration?

Jason Victor Serinus's picture

Hey Trevor,

You have a right to your opinions. And defending the decisions of manufacturers is not my concern.

Nonetheless, facts are my concern. You have misstated several things above. First, an original model is not an iteration. Wilson has released two iterations of Alexia in ten years, not three in nine.

You also imply that the original Alexia or its successor won't last beyond five years. Or, perhaps you mean that it is now obsolete. Do you have evidence to back up your statement? Is there any evidence that the Alexia's components will last less than components in speakers from other manufacturers?

Final point. Car models change every year. Should Toyota have changed the model name Corolla 17 years ago, right after I bought the used '94 Toyota Corolla I still drive today? Should I not have bought my car when I knew another version would come out in less than a year? If not, why are cars different than speakers?

You need not reply. My questions are merely rhetorical, presented as food for thought as the New Year approaches. Hope yours is a good one. And with that wish for your happiness and well being, I'm out of here.

Hopefully the first Alexia was the result of many pre-production iterations. I believe it is the job of journalists to advocate for the customer and, be critical of manufacturer's decisions. There was no implication as to the life of the Alexia, I was considering the impact on the customer. A car is a consumer item and is expected to wear out with daily use. You have continued to miss the point, why upset the previous customer when a simple name change and price increase would have far less impact on their mental health?

Changes are constant.

We're fine.
