Hello, I'm wondering, because I didn't saw much of this kind of speaker here. I mean compact speakers with a fullrange and a passive radiator. Is this something completelly off the charts ? Something not effective at all ?
Here are the two projects I made around this idea.
-Spherical enclosure made of blanda bowls (2.4L inside) ;
-Dayton Audio RS100-4 fullrange driver direct wired and no filter;
-Dayton Audio DSA115 Passive radiator.
-Pill shaped enclosure made of blanda bowls and layers of MDF (8.6L inside);
-Markaudio Alpair 11MS fullrange driver, direct wired and no filter;
-SB Acoustics SB15SFCR-00 5'' x 8'' passive radiator.
Thank you in advance for your replies on the subject.

A PR is just a vent substitute (with an additional suspension resonance).
Usually used with a small box and a vent that would otherwise be too long. That would not be the case with the pill shaped one — as cracked case says, interesting shape.
Here the 9 litre CGR for the A11ms, you can see the vent is not overlong.

I once built a 20cm fullrange in 8 liter volume.
Was only possible with passive radiator.
Its the only choice for compact volumes.
I had to use small diameter reflex port for low tuning in a little box.

Brilliant execution.
I think passive radiators are the much better option when you have a driver that's happier in a vented box, but you don't like the sound of a vented box (like me).
Check out Buchardt Audio, https://buchardtaudio.com/, or maybe you already know their products.
One thing I would try to do with a PR is fit it at the back if possible.
You added a port in the project ? Or is it a different project with bass reflex ? Thefront baffle is in felt, or something similar, how does it impact the sound ?
Thank you @Stanislav .
I saw some youyube projects using the same SB15SFCR-00 5'' x 8'' : SoundBlad and Audio Judgement.
I like their aesthetics a lot, really compact and the little angle on the front baffle is a nice detail. Unfortunately, I never had the chance of listen to this product in real.
