klippel

So I just watched an old Geddes video (see below). In it he calculates the DI for a speaker based on degrees off axis. This allows him to find what angle off axis gives him the best DI for that speaker. To me this seems like a great idea if you can DSP. Rotate speaker to desired angle then...

I plan to compare measurement differences using the Klippel NFS based on wood thickness and the presence or absence of bracing. Three different boxes will be used for the test. The drivers to be tested are the SB Acoustics SB17nbac and the test boxes are currently complete, and measurements will...

We are about to launch a new line of speakers designed using Klippel NFS. The initial lineup is as follows: AsciLab C5B Specification - 2-way Bookshelf Speaker - Dual Passive Radiator - 1" Alumina Ceramic Dome Tweeter with Custom Waveguide and Phase Plug - 5" Alumina Ceramic Woofer - LW 4th...

Visiting the Pure Acourate Sound Project in Germany - you can do it from Friday, 10th of May @ MHE 2024 -> Hall 3, Box K05 (this is an almost full exerpt (really! ;-) from my blog " Ducktollers Sonic Encounters") - I'll post the photo galleries as extra posts after the two main postings...

Just watched the latest video of the Polk Audio Reserve overview from Sound United and saw that they're using Klippel NFS!! :D You can see it at 6min:30sec It's interesting to see how they've added acoustic foams to the robotic arms. CC'ing @amirm and @hardisj I guess it goes to show why...

I have followed Amir's ASR posts and videos for a couple of years now with satisfaction. Recently, I've picked up on Erin's posts and channel for more of the same. Are there any other reviewers out there who use the Klippel test system for speakers and/or the Audio Precision system for resting...

I have an extra Polk Reserve R100 bookshelf speaker sitting in a box, so I wanted to gauge the interest on having it measured on a Klippel NFS.

I posted this on the HTM-12v2 thread, but thought it was an interesting enough concept that people might want to do it with other speakers and thus I am posting the info here as well. I had a fun little project today and wanted to add a layer of active EQ to my HTM-12v2 and wanted to compare...

I am looking for a pair of efficient (above 94 dB) full range passive speakers for my music-only setup (no sub), and have recently found some data published for PureAudioProject Trio15 Heil AMT's (measured using the Klippel Near-Field Scanning system).:) Will you, dear forum experts, please be...

Google Sheets Based Publication Each name in the List tab hyperlinks to "interactive" charts (Spinorama, horizontal/vertical directivity as well as normalized directivity, and a radar chart of the components that compose the score). Using Google Sheets' publication features allows this list to...

I thought I'd create a thread where suggestions/comments can be made on if Amir were to rank speakers based on measurements, how would he do so. As of right now, since Amir wants his rating to be based on listening tests and not just opinions, Sean Olive's Predicted Preference rating is likely...
