This is incorrect jerry. Kilppel has been around since the mid 90's and makes dozens of products and various software. This list you are referencing is simply a list of companies that have purchased something from Klippel at some point in time and have given Klippel permission to use them as a reference.Quote:

Most of the companies who utilize the NFS are billion dollar companies that offer bluetooth speakers, mobile phones etc., where a $100K + investment is basically a few pennies to them.
Ah, ok.
I noticed a fair number of speaker manufactures (and driver manufacturers) on there (including Ascend), but I guess not necessarily the NFS product.
Since there was a misunderstanding, please feel free to remove the incorrect post. No harm, no foul.
PS So, is it correct that Amir at ASR made this investment? Or some subset of the product?
On that list, I found only 5 companies that have purchased an NFS.Quote:

From this analyzer, depending on needs, the engineer adds various hardware and software modules. For example, if you specialize in driver manufacturing, you then add components for measuring various aspects of a transducer, such as BL (critical to producing quality drivers).
The NFS is basically a robot designed to move a microphone around a speaker in various sized 3-dimensional cylinders. This data is then fed to the analyzer, processed and then specialized software is then used on a connected PC to evaluate the complex algorithms.
Most companies who have an anechoic chamber also use the KA3 + measurement mic + Klippel software to take measurements.
Correct, Amir at ASR owns an NFS. There are currently only 2 possible methods of achieving these types of full range full resolution measurements. Either the speaker must be measured in an anechoic chamber (these days, easily a 1/2 million dollar investment), or by use of the Klippel NFS (which is actually more accurate)Quote:
