Separate names with a comma.
Nis, Buckle physically displaces the cone, via a stepper motor system. We attach to the cone/former, and sweep it through its range of motion....
Stephen, BL nonlinearities tend to be worse because they scale with power (BL is measured in Newtons per Ampere - the more power, the more...
Hobbes, I didn't know your name was George...:D Dan Wiggins Adire Audio
George. I've always been partial to George. And I don't know why... Dan Wiggins Adire Audio
Tirefyr, There are only 6 fundamental physical parameters of a driver: Re - the DC resistance of the voice coil (often called DCR). This...
Vb is proportional to Vas (double Vas, double Vb). Vb is proportional to Qes squared (halve Qes, quarter Vb). This is for the same...
All our driver sizes are listed at http://www.adireaudio.com/tech_papers/driver_sizes.htm and are accurate. Here's a picture I just took of a...
It's called superposition...:) The graphs above are great explanations of what happens. You don't hear each frequency on its own, you hear the...
Michael, If it was just ordered or delivered in the last week or so, the it's the Mark IV. And the mounting depth is the same. Hobbes, Because...
Seth, About triple (or more) gaps look at Figure 13. You only need the voice coil to be long enough to span into a pair of adjacent gaps....
Well, all our original design notes - and the patent application itself - reference split gap. You see, our approach can do more than just 2...
I don't doubt it exists, but I doubt it will be a useful motor... A few things: 1. Consider the BL they measure. Using some ratios from the...
Check out the most recent AudioXpress magazine. In in, there's an article on the Hageman subwoofer design. The author designs - and builds - a...
Take the published T/S parameters for the e15A with a grain of salt; the listed Re is 6.77 Ohms, which would be a dual 4 Ohm design. I suspect...
E-mail warranty@adireaudio.com and include the name used on the original purchase, so we can look up your records. They'll get back to you with...
Eminence builds a lot of other drivers for us, but because of the current limitations of their system, Brahmas would be prohibitively expensive....
There's only one story - Dr. David Hyre and myself invented and patented XBL2, and all split-gap variants. Destijl (among several others) is a...
The 12 spoke 12" and 15" baskets are the same; the 10" baskets are different. But for every 10" driver you sell, you'll sell 20+ twelves and...
Just wanted to add... We are small, but we have earned quite a few accolades and interest in less than 1 year, with the Brahma: - TN State SPL...
If you port it, tune it low. That will keep the SQ for you. You'll get a lot more output from the driver down deep. As far as EQ goes, if you...
