In most cases with ultra high price speakers one thing (many things) you are certainly paying for is a very large number of drive units.
Sensible speaker designers who realised that bling is not the way to go for good sound discovered many years ago that above two a proliferation of drive units worsens the sound quality. This is easily explicable by the number of interactions between drivers: 2 drivers - 1 interaction. 3 -3 4 - 6 5 - 10 6 - 15 and so on. Don't think about the designs with 10 or 15 drivers.
Multi-way cross-overs don't help either.
Keep it simple, good design and build quality is the way to go.
