Hey everyone, new here, UK based.

I am just starting to experiment with Open Baffle DIY, and I wondered if I need any baffle at all. Let me clarify:

I have a pair of Lii-F12s for this project.
As shown in the image, they are simply suspended from a couple of mic stands right now, as I just had them delivered, and wanted to get a first impression.



My question is around the designs I've seen used a lot with the Lii drivers. Image below:



I see this design a lot, and wondered what the Baffle brings to the sound, compared to having a really minimal frame supporting the driver, but no real baffle to speak of.

TIA

Apologies.

Just realised I managed to post this in completely the wrong place.

The main reason for a baffle is to give you more bass.  It's also the reason you'll often see the woofer mounted closer to the floor.  Because there's no box, you get a pretty strong roll off in the bass, so things like wide baffles and close-to-floor mountings are tricks to get more bass acoustically and not via a crossover fix (which usually eats up sensitivity).

I can't find the link or photos, but somebody made a open baffle speaker without the baffle (it had nice supporting hardware) and the woofers were slot-loaded or both front-facing isobaric without a baffle.

I believe a baffle prevents or delays the cancellation that occurs when sound waves
of the same frequency from the front and back of the speaker meet ...which would
yield big dips in the frequency response.

Baffle lowers edge diffraction freq - https://www.trueaudio.com/st_diff1.htm

What do you think of the sound quality, especially the bass response?

Hi,
had the same question.
Do i realy need a baffle. Hm, not realy.

Right now i’m happy with the result. But size matters.
 At least to get some nice amount of bass.

Thanks for the resources and comments. Down the rabbit hole I go!!

Is this the one you mean?

That's it. It looks cool, but unsure about the lack of baffling.

Shouldn't the question be what do you gain by not using a baffle?
