I was contacted by the manufacturer and he gave me the spinorama for this speaker: Purified 4. "The measurements are performed by IFAA in Germany within the following semi-anechoic class-1 chamber: https://ifaa-akustik.de/en/the-institute/technical-facilities/". As the name implies that's a 4...

I discovered Lange loudspeaker randomly. They do not have measurements on their websitesbut on LinkedIn I have found this and it shows excellent measurements. That's potentially the one in Atto. It looks like it is a Swiss company so I expect the prices to be high. Source ...

Analysis of the Devialet Phantom I & II measurements The Devialet Phantom speakers are small but powerful, with a unique design and excellent bass. They are expensive, but their sound quality is top-notch. I ordered a pair of Phantom speakers a few years ago (the large model in 2017). The sound...

EDIT: I added support for eqAPO and autoEQ. When you use REW on a MAC, an easy way to apply the generated EQ is provided by Apple: AUNBandEQ is a plugin implementing IIR filters. REW created an output for AUNBandEQ with frequency/gain/width for each filter. I usually manually copy each data (3...

Data analysis of FBT Promaxx serie FBT Promaxx are PA speakers which are optimised for high output. They are active, relatively cheap, easy to get and have an internal DSP. FBT is nice enough to provide a lot of datas for these speakers. Typical use cases are small gigs, your garage, your garden...

JBL PRX900 are PA speakers which are optimised for high output. They are active, relatively cheap, easy to get and have an internal DSP. JBL is nice enough to provide a lot of datas for these speakers. I used the data to generate the spinorama and derive some information. Here is the...

This blog describe how using AI Meta researcher can compress 10x better than MP3. They made the code open source so you can play with it. Can you hear a difference?

There are a lot of available data on PA speakers. Companies are used to share data mostly because buyers need them to compute how many speakers and which ones they need to light up a stadium. I discovered recently that a lot of companies published data in CFL and GLL format. GLL has a free...

We have seen recently that many cheap speakers have port resonances. It looks to me they do use basic port (a tube). I have seen a few better designs, KEF or Yamaha comes to mind. Do you have other examples? I am surprised that designers are not doing better, this is a very well studied fluid...

Hello, i randomly found Perlisten (never heard about them before). They do publish measurements with their speakers. They do provide a spinorama (smoothed) which shows a very good directivity. This large speaker is bass shy which I guess is on purpose since they also sell subwoofers...

Hello, i wrote a software which is automatically creating EQ similar to what @maiky76 or @jaakkopasanen are doing. It start to work well but I have a few questions about what it should optimise for. Here is an example: 1. is the data provided by Amir 2. is an EQ done by @fliplfop by hand which...

Backstory: M2 heats a lot and above some temperature they start to get slower which defeats the point.

Idea of the day: use a drone to turn around the speaker and do measurements (instead of turntable etc...) - noise of the drone is easy to measure and then to remove from the measurement. - positionning is also relatively easy with existing open source software. - I am looking for a drone which...
