Design a $60,000 Speaker - Start here


Hi Everyone,

Just thought for interest I'd talk about one of the most expensive woofers in the 10-12" varieties, the Accuton AS250-88-552 CELL, actually an 11" aluminum honeycomb sandwich construction. Retail price at hobbyist volumes: $1,400, each.

In addition to the exotic material, the suspension and motor assembly are also worthy of note, as they leave a very large amount of unobstructed space directly behind the dome, allowing it to behave most ideally like a piston.

So putting this together into say a modest 3 way with all drivers from the same company and of the same level, I estimate around $6k / pair of speakers for the drivers alone. Add the normal markups, and this is a $60k speaker.

Will it sound any good? I have no idea. I just wanted to share with you all where some of these speakers that cost as much as a luxury sedan get their prices from.  Obviously, my estimates are rough, and go up and down. The point of this is just a general expose.

Best,


E

Yes. It is nice to eliminate as much crossover as possible. Crossovers are subtractive, they take away from the signal. Pay good money for an amplifier and the the damn speaker sucks out the signal. Not nice. 
One can go entirely active with speakers, yes, but the speakers will still sound notably better if the drivers have passive zobel networks.


you could actually learn a great deal from Richard Vandersteen
the 7 is not built to a price point it is the best he knows how to do today and is the culmination of many many years of work and innovation
i might add that every single part and operation is subject to what I call Dutch Frugal Engineering scrutiny but at the end of the day it has to sound better - hence a somewhat conventional barrier strip binding post that can be directly connected into the soldered traces for the crossover - eliminating wire
i believe it is relevant as you yourself start the thread with driver cost


I love the magazine ads that showcase the crossover. All these parts. In some cases there is more going on in the crossover as some single ended amplifiers have circuitry. They also have notch filterers to eliminate cab resonance at certain frequencies. 

Please don't get me started on active speakers. I paid big bucks for a rack to isolate my amplifiers from the resonance and now they put the amp right in there next to the woofer. 

That is remarkable.
