there is nothing saying that they cannot, in fact I liked several of the XBA-XXXX (I'm secretly a hard Sony fanboy, even if their marketing often makes my eyes bleed). with that said the only one I still own is a single driver ^_^. it's just that going for multidriver design without crossovers that's making things overly complicated for the designers without any really clear benefit. those who think crossovers are bad will typically go for single driver designs, and those who don't think it's too bad, they will just use them. but multidriver and no crossover that's special. the overall impedance will still tend to be messy and probably low. with the bands overlapping on wild frequency ranges while being different drivers, there is always some risks of unwanted interactions like maybe getting into partial cancellation somewhere. with some crossover you can band limit each driver so if things go smoothly in the transition bands, you're in control. and then to tune the all thing without crossovers, they have to rely entirely on picking the drivers(or for sony, go as far as making them if I remember correctly), and maybe add some acoustic filters and specific internal geometry. all that for a result that isn't even more stable or objectively better than what could be done and is done by most manufacturers. it amounts to taking the road less traveled while knowing in advance that it's through a giant swamp with gators. it's doable with a lot more efforts but the chances to get in trouble are bigger. so I'd say it's a ballsy and strange decision at the same time.I have the Sony xba40 and they don't sound like a mess, they are pretty totl
now that I think about it, are all the XBA models without crossover or was that only for the first ones(2-3-4)?
