directivity

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...

Strictly between these two choices - vertical directivity or speaker radiation width (horizontal), what do you think matters more for sound quality? I've now auditioned nearly all the speakers I was interested in though they keep coming out with superb measuring speakers at a rapid rate. But...

For anybody interested in recording, check out this new data on the sound directivity of musical instruments from Technische Universität Berlin and AFMG. https://www.afmg.eu/en/technische-universitat-berlin-and-afmg-publish-high-resolution-ease-gll-data-22-musical-instruments The .gll files...

My company measures sound power to BS EN ISO 3744 within this standard the Directivity index is calculated and has a limit on each microphone position of <5dBA. Can any one tell me if directivity index should be an absolute value when checking this ? Below are some figures that have recently...

Hello, Amir! Hello, Forum! I found my way to this website through Floyd Toole's book and Amir's excellent YouTube channel. I'm hoping to find a similarly grounded approach to our fascinating hobby here. Who am I? I guess my 'hifi career' has been fairly typical until roughly 12 years ago. The...

Are there any objective means of determining the degree of speaker toe-in, or is it best determined by ear? I feel it has something to do with horizontal directivity and beamwidth measurements, and possibly room measurements. Any help would be appreciated.

I've had these two speakers for a very long time, but I've never really gone into a detailed comparison between these two side-by-side before. This exercise is going to be divided into sections, so just skip ahead to the areas of interest to you. Also, I'm going to be focusing on the Sceptres...

So, if you guys don't know, I have a speaker selector Google Sheet that you can use and narrow down the list with multiple filters (both scores, price range, measured sensitivity, physical dimensions, enclosure type, etc.). I am wanting to add dispersion categorization, but then of course we...

Hello, I want to discuss here the differences of wide and narrow directivity of very good speakers in context with room acoustics and more. One perfect speaker for all rooms. I don't think so. On conclusion of the research at of @Floyd Toole and others are that a good speaker sounds good in...

I'm intrigued by this kind of speakers. I know that there are reasons why I "shouldn't" like them, but nevertheless: Listening to the MBL 101s in a large room rank among my all-time best hifi experiences. (even though I think they have their weaknesses as well) I would like to open a thread on...
