Albert Von Schweikert will get very annoyed if he hears us calling his 'pressure release' a port!! hehehe
Anyway, as lordsummit rightly pointed out via his copied text from the VSA web site, Albert's design basically provides the listener with a much larger and open sound that most would ever expect from a monitor.
The whole idea is that we should not be listening to Hi-Fi components but the performance/music. Once setup correctly (and I personally feel that using the right stands is critical), the listener will be lessed with an exceptionally wide soundstage.
We did a demo with the VR-1's once with a customer at his home and he had been using Tannoy red-line monitors for years and he was so used to having the Tannoy's close up and toed-in with a very narrow sweet spot that when we set up the VR-1's the openess just totally upset his listening experience as he was just not used to having such a wide-open soundstage.
Don't get me wrong, you do not end up with such an open sound that they do not image well, quite the opposite, the VR-1's extract every little detail and place it exactly in the right position per the performance being listened to. You will know exactly where the vocalist and each member of the band is on live performances
As for the Global AXIS integration network this is one of the special designs on the VR-1's, even the review we had HiFi News do (January 2004 by Keith Howard), they did not fully explore the design and performance of this clever cross-over.
Many people will know that some designers are famous for using a particular crossover order, even so far as speakers coming from certain Countries being famous for having say 4th order, but what Albert has done is combine designs of different orders so that the weaknesses apparent in other desings are minimised or even removed.
All I can say is that you really need to listen to them, and if they work with your system then great. I always used to say to all our customers whether they were dealers or end users that there is not, and never will be a product that does all things for everyone, but get a good balance within your system and if something is not to your taste try something else.
We were never about selling products because they gave us the largest profit margin, needed minimal time to understand, or looked fashionable, we were always about offering people musical products without huge inflated price tags.
Sorry, I will stop ranting now!!
Enjoy your music people.
