No offense intended mwalker2, but your statement actually makes no sense to me. I had asked another x2 owner what deficiencies the X2 had that owners would expect to see corrected by a theoretical x2 (v2) and didn't get a response.
Why would (all...your word) x2 owners need to consider selling them just due to the fact a new design is released?
I've never read a bad word on the x2, but current owners apparently aren't as enthralled with the x2 as they state.
Just how bad is this $10k speaker?
At the risk of pointing out what is likely obvious at this point, I don't think X2 owners see a glaring deficiency in their speakers with the release of a new model, but see performance benefits and improvements in the new model(s) that don't seem a massive stretch to think could be implemented (trickled up, or down?) to the X2 platform, considering the X2 uses a similar configuration of AMT and 12" driver (setting aside different choices in exact driver models of course) that the top section of the X3/5 employ and also considering the X2 was at least at a glance designed as a modular system. I can't speak to how many customers bought the X2 as a lifetime set it and forget it pair of speakers or bought it under the impression that it is/would be a modular system the manufacturer would support with future modular updates and upgrades providing an upgrade path to those who want one without having to sell and then buy all new speakers, but I think I'm safe in saying some of the questions stem from the impression that X2 was intended as an evolving ecosystem rather than a static model, and so far some X2 owners feel a little left out in the cold.
Based on Spatial Audio's responses thus far, it seem X2 is not a platform at all but an unchanging and singular model. Considering the response from at least a few customers who bought the product, and their clear willingness to invest with their dollars in what is positioned relative to the X3/5 as a premium product, it is hard to argue that providing an upgrade path would not be something worth considering. A triple stack X2 with low end duties offloaded from the clearly high-end mid/woofer driver with a powered bass section looks on paper to be a formidable combination while still allowing for the existing option within the X2 for customers that want or need to go with an entirely passive model.
If upgrading the X2 really isn't in the cards, and X3/5 are truly higher performing speakers at a considerably lower price, much like the M3 and M4 seem to have undercut and ultimately replaced the M1 and M2, the X3/5 (and maybe an all-passive variant based on the parts used in the X3/5) are poised to at some point do the same to the X2 as new customers guide the product assortment with their dollars.
