Wilson's Chronosonic XVX loudspeaker over 3/4 of a million US dollars


Wonder what the impedance/-phase angle graph will look like on these puppies, looking at the amount of D'Agostino amps used to drive them, I'd say could be pretty evil.

Mistake, these are only $330,000 usd the WAMM Master Chronosonic are 3/4 of a million.

Also need D’Agostino’s amps to drive them, those green things look like 8ohm loading big power wire-wound test resistors.

George, I've only heard the XVX speakers. Different experience from anything else.

Yes, both speakers are tough loads, but anyone buying either of these probably isn't worried too much about amplifier needs (or anything else).
 
These are the published specs:

Measurements for XVX

Sensitivity 92db @ 1W @ 1 meter @ 1kHz
Nominal Impedence 4 ohms / minimum 1.6 ohms @ 326Hz
Minimum Amplified Power 100 watts per channel
Frequency Response20Hz - 30kHz +/- 2dB Room Average Response

Measurements WAMM Masters

Sensitivity 93.5 dB @ 1W @ 1 meter @1 kHz
Nominal Impedance 3 ohms / minimum 1.77 ohms @ 310 Hz
Minimum Amplifier Power 100 watts per channel
I heard many Wilson beasts at audio shows, nowhere near my price range, damn ugly, and not overwhelmed by them

however, I never saw or heard them in a large space which makes more sense for them

min 1.6ohm ain't for most.

I am always suspicious of seeing such low numbers in a dynamic speaker in the bass. I took apart one speaker and saw circuits there deliberately designed to reduce the impedance. It made the speaker "discerning" of amplifiers.

Wilson encases all his crossovers in resin so it is impossible to do the same analysis, but I am so very very curious if this dip is necessary, or a high end secret sauce.
@erik_squires ,
+1.
I, too, wonder why a speaker designer would design a speaker with such low impedance? -Well, I understand, that such a design contributes to the sound of the speaker, but, when it comes at the price of limiting the amps capable of playing them then why not just sell the speaker and the amp the speaker was voiced with as a combo?

@gdnrbob

Sometimes this is legitimate, and in the past, I could see that it was due to poor design tools.

Like in the early Genesis era. Damn, some of those crossovers are horrible in terms of impedance, but I can see how they got there due to manual trial and error.  Attempts to get a certain sound out of the speaker, and not having very easy tools to help you optimize frequency AND impedance at the same time.

I can also see it with something like the giant Apogee true-ribbon speakers. The very technology caused 1 Ohm impedance, but with dynamic systems, I scratch my head.
When solid state-generated watts became cheap, speaker designers started to care less and less about the impedance of the models they were creating.  Kind of a corollary of the law of supply and demand.

@twoleftears 

I think this is a good observation.  If Genesis only had tube amps, they probably would not have been able to release some of the speakers with the impedance issues they did.

On the other hand, I think that with the design tools and computer based optimization, there is no longer any excuse.

erik_squires I took apart one speaker and saw circuits there deliberately designed to reduce the impedance. It made the speaker "discerning" of amplifiers.
So it wasn’t a Conjugate impedance compensation load that you saw, that makes an amp sees a constant impedance load across it’s working range??? Your saying it was deliberately done to be detrimental to weaker amplifiers that maybe demo’d with them. Please say who these terrible cads were that did this kind of thing???? And if it was Wilson or not?

Really!! you and whoever else is living in a dream world, if you think this is Wilson Audio design criteria

Are you guys listening to yourselves
I’ve heard many of their top range, that are a b*****s to drive and I can confidently say these will give better bass because of it and their deign principles than anything that’s 8ohm and 100db efficient and called Klipsch or similar.

Cheers George
Hi George,

Please share with us what the difference is between the phase angle of an impedance, and the phase angle of the speaker's output.

Thanks,


Erik
I asked you that above because, I call BS on it, and you came back with this rubbish


And you can’t even get that right, give up.

What one of what you are referring to is "phase shift" in the mid highs of Class-D’s and caused by the filtering of it's output filter.

And the other for speakers is the capacitive "negative phase angle" (EPDR) loading , not even related to each other.
Go away please, you have lost all cred.

It’s cheating of course, but some of us enjoy “ low efficiency but also low trash “ speakers that are an easy load, low pass optimized with a power factor corrected feed forward bass amp and another optimized high pass amp with just 5 active components in the signal path....

somewhere... I remember a class on systems engineering...

oh and because the room is part of the system. 11 bands of analog EQ below 120 hz

your mileage may vary
Does kind of remind me of technical amplifier discussions pre Matti Otola...

but it measures great

but it sounds like crap

but it measures great

maybe we should measure something else ?
Of course there is still the high negative feedback club in love with sine waves..,
Cracks me up you amp guys sweat over tenths of a % and tolerate a paper Wilson midrange ( for example as let’s say representative) that is out of phase 50% of the surface area of the cone at the crossover point...

$500 to scan your favorite driver and know the truth....
Go away please, you have lost all cred.

Where's the stinkin' cheers when we really need it?
🤷‍♂️Here's some 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
Cracks me up the way everyone acts like any of these specs matters. Definitive Audio is a huge Wilson dealer here in Seattle. Their flagship Audio Technica/Wilson/D'Agostino system is $1.3M. I heard it. Heard it right after one of their guys spent a whole day fine-tuning to present it to whoever has enough more money than brains and ears and so can be talked into buying it. Talked into it by blather just like this thread, all about specs, not one word about how it actually sounds when you listen to it playing music. Which is powerfully dynamic and,..... that's about it. In terms of, well pretty much everything else it can't hold a candle to mine, which you could have for about the Washington State sales tax you pay on their $1.3M monstrosity.

No amount of specs is enough if it doesn't sound good. And it doesn't. 

We now return you to our regularly scheduled recitation of irrelevance.
I am pretty sure only the relentless are powering the xvx. The other amp is to power the wilson subs in the corner. I heard this setup at axpona last year it is pretty amazing.

There look to be 6 x amps on the floor.

Hi OP,

As soon as you finish your course in AC circuit analysis, and filter theory I'll be happy to answer any questions my may have had.

Best,

Even Klipsch $20Kusd P-39f flagships at 75kg each, get harder to drive the further up the flagship ladder they go. Min 3ohms and 50'-phase angle right where the power is needed to keep the bass tight and dynamic.
https://www.stereophile.com/images/archivesart/609Klipfig1.jpg

Stereophile
" A nasty combination of 4 ohms magnitude and –50° electrical phase angle at 80Hz. The three woofers do demand a significant amount of current to keep up with the horn-loaded midrange and treble drive-units." 
 So to those that bag out Wilson, bag out Klipsch too for purposely making their upper range speaker too hard to drive with average amps.

I don't think I have laughed so hard in months.

Whoever said, "There is a sucker born every minute" was so right.

Hilarious!

Why?  You could BUY most orchestras for that same $ and hear the actual MUSIC as opposed to listening to it from a BOX.

Hilarious beyond belief.  

Cheers,

It is hard to imagine any designer believing that lower speaker impedance is a good thing. My guess is that the higher power output of many amps when driving lower loads is (was) the main motivation.

Right??


Those are some of the fugliest speakers I've ever seen, and this is from someone who happens to be a Wilson fan!
Those Wilsons are simply irrelevant.  True innovation with speaker design is taking place many places, but always far from Provo.
When Wilson markets a PTS to match your Ferrari, they mean it. That is kind of the market for this except the question is which of my Ferrari's? According to Stereophile it is $329,000. The limited oligarch-grade WAMM Master Chronosonic is $850,000.  
Why wouldn't you place your components on a stereo rack.  My wife would kill me if I ever thought of making a room look like that.
Anyone out there want to lend me a few million so I can get this system?  If you do, you’ll always be invited to listen and make your own judgements.

😁

Not that I’m defending the price of these Wilson speakers...but...

^^^^ This is a strangely common remark made by people who scoff at very high priced audio equipment. I’ve lost count how many times I’ve seen it. Some say "you could hire The Stones to play for you personally with that type of money," etc. Even as a joke supposed to make a point; it just utterly misses the mark.

What someone gets with a super high end system is generally what most of us want with out less pricey systems: the ability to hear a WIDE VARIETY OF MUSIC played by a WIDE VARIETY of favorite or known musicians, in the highest quality possible. Even if you just stuck to listening to symphonic music, the point is there are a huge number of recordings by heralded orchestras, conductors, classic performances, performers contempory and deceased etc, that a great system will allow you to hear in the best possible quality.

Then add to that a wider range of tastes one may have - rock, folk, pop, R&B, electronica etc - and you have an endless array of music and great performances to hear in the highest quality. So, no, you could not purchase anything LIKE the array of music by known musicians for the money you pay for even the highest priced Wilson systems.

One can certainly try to evaluate the performance/quality-to-cost ratio to render a critique of these high priced items. But this weird critique "you could hire live music for that money" should just go away, it’s so nonsensical and so utterly misses the point.

(Apologies richopp...this just happens to be one of my pet peeves)


interesting how every different hifi forum has a different take on the big Wilson's reflecting the particular forum culture and membership.

no right or wrong to it, but the differences are dramatic.
Anyone who psychologically needs these speakers really needs the pretty little speaker wire trestles.  Anything less will make your soon-to-be ex-friends worry that you are actually taking you meds. 
@prof 

Agreed.

Seems these type of threads always revolve around cost rather than sound quality. I've heard the XVX many times, with the Chronosonic subs, and with the right supporting gear, they are some of the best out there. IMHO of course. BTW, if you can afford the speakers, you can also afford property supporting gear including amps that can drive them.
the gate ( sold out ) last night for Grammy nominated JD Souther was $30 k. He played 3 hours with a short break. You do the math on a decent nite of listening....

he was awesome BTW...great storyteller, emotional connection to the songs...covered some artists he admires.....

Los Lobos is up next....
If I was worth a couple hundred millions dollars I may consider something like this. But....... alas I am not. Better feel like a godamn orgasm everytime I turn it on. 
hi, as for the six amps, on the floor, probably one each for the sub's, and i guess they were changing amps to show you, you don't need relentless to drive them,  i have wilson speakers, and to my knowledge , wilson only make single wired speakers, as they really don't want you messing around with a whole mess of cables, with their speakers, for sound quality 
it would be a great demo, 400's on speakers relentless on subs, and so on, what a great afternoon  mixing up those six amp around, 
unless you’ve heard a wilson speaker in your home criticism is conjecture at best.
it’s tiring that every Wilson thread brings out class envy which has become so prevalent in our culture. I can’t afford a Ferrari but have no feelings one way or another about the owner as it has nothing to do with me. fwiw I own ‘budget’ Wilson’s and remain quite pleased.

not equally on every forum. it is particularly prevalent (and tiring) here. on some forums it's chill enough that Wilson Audio participates. would never work here.

forums and the 'vibe' come in all shapes and sizes. no right or wrong to this.
+1 4425... 100% with you!

If you mean pretentious dealers, I'm with you.  :-D

But lets not ignore the opposite is also true: Snobbery.  The belief that money = quality and that certain brands and only those brands can prove my audiophile credentials.
They look like something out of an “Iron Man” movie.
eric.. can’t argue with your comment. snobbery is unacceptable at any level and it’s been a problem with some dealers but they pay a price,  which they may not even be aware of. an audiophile that’s a snob is just a jerk. 
I myself wouldn’t own a speaker with the midrange driver wired in polarity opposite the woofers and tweeters, no matter the price. But that’s just me. I also don’t care for redheads.
Has anyone ever heard one of these Wilson's in a system and it sounded really good? Just curious. Because I never have. Not that I blame the speakers. Everything matters. But it sure is odd that I have heard great systems with lots of other speakers, but never with Wilson's. It also seems, now that I think about it, every one of those Wilson systems was presented with a very obvious air of snooty better-than-you-ness. Just sayin. 

But seriously. Anyone? Beuller?
I've not heard these speakers. I generally have a favorable opinion of Wilsons, but the position of the tweeter bothers me ergonomically.

I feel like I'll have to keep lifting my head up to hear them correctly.

Am I mistaken??

Mike: The Audiogon discussion forums have changed. The days of IMO or IMHO are gone. Several members seem to think that their opinions are fact - in a very bloviating way. Their chronic posts are as fatiguing a noisy tweeter.
