Flawed? Wilson's Aspherical Propagation Delay


Greetings,

I've always wondered about this...

Recently I read an interview with Alon Wolf who stated that separating drivers into boxes that are adjustable would not work for him because the crossover would need to be reworked or adjusted.

Wilson is proud of their adjustable cabinets in their upper models, but I'm wondering how, in technical terms, they avoid phase and time errors and as Alon pointed out, how the crossover deals with the drivers in different locations and different angles?

I've heard Wilsons set up before and there is a distinct advantage to the adjustable enclosures when they are setup optimally for the listener's height and distance from the loudspeakers, but is there a shortcoming or compromise in doing so?

I own Wilsons-and love em. No other speaker is for me. With that disclaimer...

The OP seems to be transferring Alon's statement based on his speaker methodology (..."would not work for him b/c the crossover...") to Wilson's methodology. Wilson take this into account and his crossovers are specifically designed for the Aspherical Prop. Delay. It's a system.

Alon was talking about "his system" He makes good speakers to! Just in a different way...

Buconero117-sorry in advance here. But, ok well you forgot "successful" in your biz model quip...So if others can make wilsons for one 10th the price, why haven't they? I'd gladly buy Alexandria X2's for 1/10th the price-assuming the same performance level. Maybe the sum of the parts is greater than you may think? I always find it odd when folks attack Wilson for their business model. If you don't like the sound of their speakers, that's your opinion and your certainly entitled to it.

Their business model seems to be a success and that's why they sell and win awards... we all want successful business models in the high end because that funds r&d for better products down the road. And, at least in the USA, provides jobs, benefits and profits. Therefore helping our economy and our gov't with more taxpayers...I don't think this is a "guy thing" But this is just my opinion I guess...
Thanks for the response thus far...

To clarify, I am a Wilson fan and own their speakers. To my ears they are more fundamentally correct in reproducing music than just about anything else I've heard in my price range. I'm not trying to create a Magico versus Wilson thread, but I've always wondered about Wilson's propagation delay. Perhaps it's the best thing in the world and is a great part of why their speakers sound so good, but if there is a downside to this method, can anyone think of what it might be? Sounds like the adjustability may be hugely a positive with little to no negative, but does it have an effect on how the crossover operates? If the crossover and aspherical propagation delay is a "system" shouldn't the crossover be user adjustable too? Please correct me if I'm mistaken...
Designing decent user-adjustable crossovers would be a lot more complex than it sounds. Adjusting the array to restore the correct speakers-to-listener geometry makes a lot more sense to me.

The dowsides are greater diffraction, as Shadorne noted, along with higher cost, greater dependence on trained professionals for initial setup, and introduction of the opportunity to screw things up.

If Wilson used active crossovers then they could offer adjustable x-overs at reasonable cost.

Frankly I am with buconero on this one, at least in regard to the very large Wilsons. I have no beef with the triangular sloped baffle on the Watt Puppy - as this does look like a genuine attempt to adjust for dispersion & maintain good diffraction characteristics. It seems Wilson is doing much the same as any manufacturer at the ultra-high end of the product range: countless questionable additional benefits that justify an astronomic price tag. To be fair this happens with cars, skis, watches, electric shavers...you name it! So I don't want to imply that Wilson products are inferior in anyway - they both look and sound great!

Flawed, yes. Its a business model thing. Think about it, the bigger the 'boxes', the higher the price you charge. The 'effect' of Wilson speakers can be purchased at one tenth the price they charge....
Which "Wilson effect" are you talking about--low level resolution where you can hear the air coming out of the trombone's bell?
