Acoustic Horn Design – The Easy Way (Ath4)

well it seems that the cooking is done in the studio (and is the part being complained about)


just a personal opinion but i've always felt a tilted response is favored because it's a blanket solution that tends to homogenize things.


are we going to start designing waveguides/speakers in different flavors, that seems a divergent path rather than come to consensus.
 
Hi, I'm liking tilted response. It sound better to me, all the time (I've never had feeling to turn a tilt off from my headphone eq. If the tilt is not there, argh, can't listen). Maybe there are distortion or something that makes me wanna do the tilt, don't know. I just prefer tilted. It's more fun to listen to, I don't want be distracted by the frequency response and tilt helps. Never mind what a graph says. Straight flat line is probably a man made illusion. It looks nice though and visual perception has more brain cells involved than hearing so it naturally feels better until the conscious mind starts to doubt the sound and steer to something else, flat to the ear, not to the eye.

Tilted response for me as well.

Since the issue of standardization in mixing practices has been brought up I'll add this. I've been listening to Dolby Atmos mixes lately, and even with Atmos turned off and just using stereo, they sound MUCH better. Rock solid center is a consistent feature. I suspect this may be because these Atmos mixes are being done in proper film studios vs 'music' studios. I've been reading lately and stories such as those of tenured engineers who've admitted to mixing big name music on a laptop in their hotel room is stunning.

I do think that we are headed in a better direction though. If you just look at your local instrument / pro audio shop, 10 years ago there were plenty of direct radiator 'monitors'. Today it's almost exclusively proper waveguides with rounded cabinets.

Audio enthusiasts and industry may finally be headed for an intersection!

With waveguides from this thread, proper room curves, and no enormous consoles between listener and speakers, I would argue that we home gamers are actually in a better spot!

You may not like the show, but the audio on Disney's "Mandalorian" is extraordinary, as is the visual. The film business is so far ahead of the audio one that it is alarming. I found this out when I looked into video compression. The video guys had done an enormous amount of work on perception - way beyond anything done for audio.

And in video they accept the science. In audio it's still "sounds good to me, that's all that counts."

^ Good point!
 
I think that holding a DI to a lower frequency is a good idea, it just gets big and/or complicated at some point and no longer worth the extra cost and effort.

Here's a link to a 2020 thesis submitted to Aalto University in pursuit of a masters, Improving Two-way Loudspeaker Directivity by Olli Kantamaa

The statistical analysis demonstrated that the increase of the loudspeaker directivity in the low–middle frequencies can improve the subjective sound quality significantly. Increase of the low–middle frequency directivity improved clarity, reduced sound colouration, improved virtual sound image definition and transient reproduction compared to the conventional loudspeaker directivity.

directivity at low frequencies was increased actively, using a secondary transducer and signal processing. The secondary transducer cancelled sound behind the loudspeaker creating directivity in the frequency range 80–600Hz.

I tried doing this using a combination of Olli's active noise canceling and Dutch & Dutch's 8C passive cardioid design. Unfortunately, I don't know how to do the active gradient with delay method Olli used so I'm sure his results were better. If I knew how to do the active gradient cancellation in SigmaStudio I probably wouldn't need to add the passive D&D portion.
