Spider27 Posted June 30, 2022 Posted June 30, 2022 (edited) Really love the look of Pure Audio Project Open Baffle Speakers. I am sure that members here owns similar type of speakers for daily use. I just never tried in real life but watched youtube video and sound is very very impressive. One quick question. Is there a benefit of having 3 separate baffle boards instead of one large baffle? Not sure if there are certain benefits in terms of sonic or it is more visual purpose so middle board or top & bottom board with different colour. Thank you.... Edited June 30, 2022 by Spider27 1
muon* Posted June 30, 2022 Posted June 30, 2022 You can upgrade a single module instead of remaking the whole baffle. 3

Yes, I thought that it would be the case since they offer different tweeter options, ribbon tweeter option etc. Not sure if there is any benefit of having multiple boards in terms of sonics or just upgrade friendliness and visual benefit.
Nada Posted June 30, 2022 Posted June 30, 2022 Modular design may provide advantages: 1. Vibration isolation, if used with clever design, so the midrange isnt contaminated by woofers 2. Transport - breakdown into a small package to lower freight charges 3. Aesthetics - for those who like the curved front baffle look: 1

Aesthetics - for those who like the curved front baffle look: Is it your speakers? Looks fantastic and fully agree on those advantages. Please correct me if I am wrong and one possible downside is bass performance? I thought that bigger the front baffle is, more bass presence from open baffle design. If it is cut to modular size for each driver, then woofer has less baffle size so lessor bass output?
Nada Posted June 30, 2022 Posted June 30, 2022 Photo is off the web- its just to show the curved panel look that some will like and some not. Bass performance will depend on total panel area and dimensions in an OB. As long as the gaps between individual panels are small, bass will "see" just one panel. 1
MrBurns84 Posted June 30, 2022 Posted June 30, 2022 @Spider27 Have a look at these: https://www.decware.com/newsite/Caintuck.html I really like the sound of OB, but from the design i heard, which was a single 12inch driver, i felt that the bass needed to be augmented by either a sub or an additional driver. That open, spacious sound is something to be experienced. 1
tesla13BMW Posted July 1, 2022 Posted July 1, 2022 Separate baffles has a lot to do with isolating the low frequency vibrations of the woofer driver and baffle from getting to the mid and high drivers. I'm looking to suspend the drivers in a faux baffle i.e. close to the baffle, but, not touching and seal the small gap with something that wont transfer the vibration. The curve is also to do with trying to get physical alignment of the acoustic centre of each driver. Some say "just do it in dsp" which is fine for a closed box, but, for open baffle a delay of a driver in front of another driver will align the frontwave from drivers, but put the back wave even further apart. This is something I am trying to sort out because the difference in acoustic centres of a 15" or 18" woofer to a 8" mid/wide range and again to a planar tweeter is huge and a stepped baffle will cause defraction issues etc. All part pf the compromises. 1

Depending on what frequency range you operate the driver(s) over, you may find that the issue is only a small fraction of a wavelength.
