One could ask: what is it you want to achieve and like in particular with with wideband speakers/drivers? A noteworthy trait is their alluring simplicity sans cross-over of any kind, and another is they're a single point source per channel - with all that entails and the advantages that offers. I would imagine though some people also have an inkling towards their often found character or signature (as elaborated on by poster @larryi just above) as a certain flavor of sound they like, even though it may deviate from a more "correct" imprinting in certain respects.
Where a point source goes Tom Danley's Synergy horns are a potential "having your cake and eat it too" scenario that offers the advantages of a point source without the pitfalls of most wideband drivers. They do need a cross-over however to handle the response of the different drivers (that sum as a single point when configured the way they are), be that active or passive, and presently they're only found as pro segment offerings - which nonetheless shouldn't keep one from acquiring them for a home setting. Danley does have their more domestically oriented Signature Series coming soon, for those interested:
