I own a highly-modified pair of Vortex's, but my mods were mostly in the cross-over & bass inductance coils - to indescribable success after hundreds of hours of burn-in from clean over-power. I bi-amp the Vortex's with Tubes, & high-current on the bottom-end.The existing drivers seem to be matched fairly well to that Vortex design; the existing tweeters (Seas H535 tweeter) is a VERY good sounding tweeter 'if' in the 'right' speaker & electronics design. I heard many pairs of $4,000-$5,500.+ newer speakers and they don't sound immediately 'better' nor not nearly as 'romantic'. I want to keep them that way, however...Question: I would like to find a fairly less efficient tweeter driver (& with more power handling?) but that can similarly 'match'. However, because I bypassed the hi-pass resistors in the original cross-overs for better sound quality -they sound a bit bright or 'tweeter-hanging' (like a Thiel or B&W speaker). Please note: I have already tried the newer-generation Seas H535 replacement (from Madisound Parts?)with the ferrofluid-cooled coil and supposedly has impedance curve helping with power handling - but these replacements also sound just as bright.Can you make any near-perfect replacement recommendations that will not cause a mis-match of components (and that does not require me to change much, if any, components in my well-burned-in exotic $1,200. worth of home-made crossovers?In case you don't remember the 'Seas H535' here is their literature:Regards, Tony

The Vortex Screen
I know this is a few months old but I just found this thread. I have had my Screens for a few years and they smoke all of the speakers I've ever had before including my very well reviewed Celestion SL6S's and Infinity RSII B's. The soundstage of the Screen is phenomenal and they do everything else so well I have never even though of upgrading since buying these in . I paid the huge amout of $400 for these on ebay and It would take many times that to get anything comparable. Even well used. I have what I believe are some of the last of the California made systems bought new in and they are very well balanced. They do require room to breath though. The single box model was made several years earlier and it's a shame yours were damaged. The later models are a two piece system with a time aligned mid and tweeter in a configuration similar to a Vandesteen with the stretch cloth sock that hides the small enclosures of the top module to give a boxy appearance. I know from the factory paperwork that Von Schweikert used Dynaudio and Audax drivers along with his own crossover design.
I do have all the documentation and a copy of the excellent Stereophile review in which these are spoken of as being considerably better than Thiel, Snelll and the highly regarded Vandersteen 2c. If you are interested I can send you copies.
