I don't know the specifics of this particular speaker Buddha, but if you have sixteen 8 ohm drivers, you could wire four groups of four in series, then wire these groups in parallel, for a total impedance of 8 ohms. Is that clear? I wish I could draw it for you.
Perfectly clear!
Thanks!
I had been thinking either/or instead of "both!"
Roger Russell knows a thing or two about redundant drivers
http://www.ids25.com/
The IDS-25 is a single column of identical wide-range drivers that cover the entire frequency range. The entire frequency range radiates from the same line source.
There are no crossovers, woofers, mids or tweeters.
In addition, there are 25 drivers, each of which will handle at least 10 watts. The entire column will handle 250 watts and still not exceed the single driver power handling.
The heat dissipation capability at high power is outstanding with 25 voice coils per channel. A single coil used in one large woofer is not able to dissipate heat as effectively in comparison.
Also, since the system will handle such high power over the entire frequency range, it means that the mid and high frequency peaks can be handled effortlessly, far better than a system having a single mid-range and tweeter
92.5 sensitivity
20 to 20 response
If I am correct in my assumptions, this would end up as a 4 Ohm load
And like Bert said:
Those won't work Keld. You need two wires to each speaker.
The thing that worries me is the high frequency lobing, directionality, and so on.
How far off axis (up and down) can you get without wierd stuff happening?
They are very thin!
I agree. The drivers should at least be pointed towards the listener.
Hmmm... Multiple small, full-range drivers, equalization to compensate for driver roll-off... Sounds like a Bose 901! Okay, not fair, his is a line-source. Like an Infinity IRS. So he holds patents for EQ and line-sources? I hope they're about forty years old, or I could see him landing in court.
To be fair, I haven't read the patents. There may be something unique in there. I just don't see it.
This is strange. From the U.S. Patent and Trademark Office Website:
Patent Number 4267205: Process for low-temperature surface layer oxidation of a semiconductor substrate
Patent Number 3705501: Distributor with rotor advance input control
I know I risk having to turn in my audiophile membership card, but I found many of those prices very off-putting.
I know, everything in audio is worth its price and I'm lucky things don't cost five times what they cost....but, sometimes, I just don't relate to the stuff in my own damn hobby.
Sorry, what prices? The ClairAudient, at $54,000? or the IDS-25, at $18,900? Or something else? You lost me.
Edit: Oh damn, you meant the show report! Never mind...
