Will an angled enclosure effect the sound of a passive radiator?


I am looking to make a bluetooth speaker for a school project and was wondering if an angled enclosure would effect the passive radiators sound production, Would it mess with the pressure and cause one to move faster or would it not make a difference at all?

thanks guys for all your answers my project seemed to work with no major sound inconsistencies
I hear exactly what you are saying but, there are secondary concerns, and they have their explanations. Some of this gets into the lore of speaker design, and is generally tightly held as it is part of what can make a speaker company successful, vs reaching up to mediocre by chance. Clarity was purposely not there. :)

I’ll go back to lurking in any speaker discussions, and not increase or create confusion...
The linked pictures relay upper frequency response issues related to edge diffraction and loss of bass response also due to diffraction. I am confused with the post’s reference to "resonance" and "in the box".

@teo_audio - that is very interesting.  I would have responded that there shouldn't be much impact on an angled surface.  In fact, I would have thought that it would improve the issue with standing waves (as many speaker boxes have been designed with angled back panels instead of parallel back panels).  I would have commented that it's important not to create an area inside the box that is so constricted.  It's important to have a lot of free air space for waveform pressure.
Depends. All you can do is try it out. At low frequencies the bass should be uniform and move the passive radiator evenly. But since a passive rad has no support other than the front surround in most cases, you can eventually get into a situation of having uneven sagging.

I HAVE seen a slanted baffle box cause a bass wave, a sustained bass note from a synth recording..cause a bass wave to ’walk around’ the periphery of the woofer surround. Yes, a distortion walking around in a circle, modulating the woofer surround in a repeating circular pattern.

This was on a nominal 7" woofer, a sealed two way bookshelf speaker, with a fairly sharply angled baffle.

So it is possible to get a modulation going, one that is uneven.

your problem is that secondary modulations and interference/beat frequencies can and will appear in the box with the angled/sloped baffle. Eventually..something will work in exciting a problem into being, just for the one given recording. If unlucky, you’ve built a easily excitable mode. these problems can occur in standard rectangular construction, but it is just..less likely to be an issue in standard design shapes.

See olson’s work on box shape resonance results in the bass.

(the tiny circle in the images is the driver location on the box shape)

(ok. It was an NHT speaker and the song came off a Tangerine dream album. It was the mixing harmonics that did it. https://www.youtube.com/watch?v=AK9zKafP-TA )
