WILSON ALEXANDRIA XLF SPEAKERS-

I can’t claim to know DV’s thought process, neither am I claiming that this particular driver was used or was not modified, but the ScanSpeak Revelator R29 series is as close to idealistic as it gets for an ambience tweeter. Its output rises in the upper frequency band and it has rather high sensitivity(94.5dB @ 2.83v/1m) to match the Alexandria's. The only thing it has going against it is its increasing directivity at higher frequencies which is inevitable with most tweeters.

When it comes to well known soft dome brands(ScanSpeak, Seas, and Morel) their mid to top of the line models feature ressonance freq around 470Hz to 580Hz which is as low as it currently gets for 1" dome tweeters.

BTW – Maybe I'm mistaken but I thought DV used electrostatic arrays instead on the WAMM?

some might take this the wrong way and others the right way, but other than the X-1's, my experience is that Wilson Audio's top of the line speaker (WAMM's and Alexandria's) seems to have so many good things happening all at once that IF there is something lacking it's too minute for me to hear. I for one have an organ recording that broke up the MAXX-2's bass drivers, but on the Alex-1's they sailed right through it. of course i couldn't afford either super-speaker, but the sense of limitless power, dynamic range, and frequency extension is certainly there. OTOH, Wilson can't quite deliver the ultimate experience for a lot less money (let's say $35K) which will forever be a disappointment.

The WAMM's did indeed have a 9 element electrostatic array for the "super tweeter" section.

i really think i should clarify my comment about Wilson being able to make a speaker that "does it all" for $35K. Wilson Audio is fairly unique in constantly experimenting with new materials and designs and the customer has to fund these efforts along with the actual product. the company has to charge accordingly while even testing and improving systems not yet ready for sale. and sometimes you can get your speakers upgraded but not always.
you do get the best dealer support around and i imagine if you're no longer satisfied with what you have you get special consideration if you want a newer model.
but i have to reiterate that the Alexandrias are astonishingly better than ANY of their other speakers and there is "no going back" in my opinion after hearing them.
whatever nits and issues may exist with the Wilson "sound" simply melt away as
you audition some competently recorded acoustic music. i can't quite understand
what accounts for this effect. but it makes you wish you had the money, end of story.
OTOH many other manufacturers are not quite as busy making newer speakers or reinventing current models, so you can get a very musical speaker for a lot less money comparatively. i personally had to settle for a really excellent speaker with a cabinet finish that could use some improvement compared to Wilson or Rockport.
but... the drivers, the crossovers, and the stiffness of the enclosure are pretty far up the scale of "really good", so i enjoy listening to them and frequently dust them off so they may look their "best" - at least from a few feet away.

Hi FrenchFries,

When you say your experience other than X-1...did you mean you have compared Alexandria to X1 and found X1 lacking...or that you have not auditioned X-1? Thanks!

I own a second-hand pair of X1s which i enjoy...but am aware there is an upgrade to take the speaker up to Alexandria (entirely replaced tweeter and mids cabinets, crossover and wiring...plus damping for bass cabinet).

Thanks for any advice on X-1 if you have compared.
