Lots of ways to move air.
Most technologies can work well.
For cones and domes in boxes it's all down to the implementation, imo. Many I wouldn't take on a dare, but some have really worked well for me. I'm not aware of anything particularly special about the design or materials, but Leema Xaviers were probably the best 'traditional' speakers I have owned. A moderate sized 3-way, they just sounded right and also ticked my 'audiophile boxes' like neutrality, rez, focus and dynamic tracking. Some JBL L110 vintage boxes were also great.
For the ultimate rez (and slam) Justin's (user211) Apogee-based Interstalla ribbon speakers driven by his Accuphase mono amps are jaw dropping. I'm quite a high rez kind of listener but these were just a bit too much for me! Great fun to visit, but I'm not at all sure I could live with them. TMI.
Electrostatics - I never could get on with hybrids but I have enjoyed some full rangers, most notably Martin Logan CLS2z, and Quad 57 can be great, too (but there are some really drab sounding ones around as well, probably in need of a refurb). Both really need a sub for full range music (electronic or orchestral), and that's a real can o' worms that I never got close to properly sorting.
Horns - usually too coloured for my tastes. They can shift air very impressively, though, and can have fantastic resolution. I had a pair of Avantgarde horn hybrids for quite a few years and they worked well with minimal horn colouration, so it can be done.
I've settled on flexing carbon fibre petals integrated with a cone bass cabinet for the last 7 years, and couldn't be happier.
Loudspeakers are all idiosyncratic and very subject to personal taste, and it seems to me that the more expensive they get the increasingly different they sound from each other! Which is an interesting observation in itself.
