Your advice to speakers designers


What would it be?
I'd say - instead of building great furniture that also happens to sound good give us great sounding speakers that also happen to be acceptable furniture.

"With some designs I see a wall of drivers and with others just two or three. What do they try to accomplish with so many drivers?"

See what the designer has to say!  I'm sure he has something specific in mind.

"I always thought that one driver is a theoretical ideal." 

Out in the real world, theoreticals are secondary to practicalities.  A single driver can work well for some things, not so much for others. 

Build an efficient, true 8 ohm speaker in the $600 price range that will mate well with lower powered amplifiers for those just getting into high end audio. 
I'd say to them, to offer their dealers a set of "loaner" models, where the dealer can take one's credit card for security and the speakers could be setup in the customer's home, to see if they work well for them, in the room, with the associated equipment, etc.

hey designers or builders or whoever! anyone got scraps of vinyl veneer handy? i need to refinish my speakers -- they're both need external aesthetic work!

A crossover with variable levels for the drivers will save a ton of money and cash on cables. :)
