Design a $60,000 Speaker - Start here

Bump...  Sonus Faber..  the drivers on some of their lesser range look pretty cheap. I dont esp like the sound from the base tweeter they use.
Back to 60k speakers, that 11" accuton is a beast! But why 8 ohm? The parameters call.for a large box, so 2 in parallel to get a decent sensitivity rating wd mean well over 100 litres..
Another option is isobaric, using the excellent SB 9.5" satori woofer. Best ’rear end’ of any driver imo.

Greed makes the world go round, desire feeds it. We control our desire and greed fails. Whatever we buy, its price is determined by what the market will bear and that has nothing to do with value.

I have an Audiokinesis speaker system (2 front and 2 effect speakers) where most of the cost has gone into the design, cabinets and crossovers - the drivers are quite standard (but selected) pro-sound drivers. Thereby,. the cost of these speakers are kept reasonable.

Formerly I had the Dynaudio flagship speaker, the Consequence, with more costly drivers. In my case (with a quite large room), the Audiokinesis system sounds better, it plays better "with" the room, but this may also be due to not giving my Consequence enough power. Even with a huge Krell FPB600 amp! So yes, I could get good sound, but only at full power, and even then, two Krells would have been better. Good drivers, in an over-controlled speaker, may not be the best bet. On high decibel levels, I got what I wanted, the Krell going into pure class A operation (auto-adjusting) and the speakers STARTING to dance and sing. But then the neighbours came complaining. The Audiokinesis system doesn’t have quite the refinement. But it plays better with the room, and in my context. So I don’t look back.
A plus with speakers with moderate cost or standard drivers is the DIY factor - it is possible to experiment, without spending large amounts of money. I changed to PRV compression drivers in my Audiokinesis system. Not as good as beryllium drivers, probably - but a step up, for low cost.

60k speakers is veblen goods territory. Anything for home use priced like that is - IMNSHO.
PS. 60k worth of home equipment carries the annual secondary carbon footprint of 20 tons of CO2 ( connected to the manufacture). Add the electricity used for the operation and its carbon footprint.

Not to take away from Eric's thread, but completely related, imo. A question for Eric, and the rest of you. One of the best and significant speakers of all time, especially for the money, were the Dahlquist DQ10s. None of those drivers were costly. Same woofer as in the Advent. Brilliant design, engineering, and thinking outside the box ( no pun intended ). And, a 5 way design. Carl Marchisotto, Jon Dahlquist, and a few others, all involved. How was it they sounded as good as they did ? I could imagine a re-do of that speaker, using the best drivers, best crossover components, a heavier mass box and frame, etc. I had a few pair in my life, and enjoyed them, with larger ss amplifiers. Opinions please. Or, should I start a separate thread ?
