I don't know about open baffles, but mine are closed each with one 15" woofer , two dome mid-range drivers, and four dome tweeters. But most importantly are the other woofers placed in the back. They are 180 degrees out of phase with the front speakers, and thus overall produce a push pull effect, thus placing the low frequencies throughout the entire full room. The effects are absolutely incredible.

Can you make a semi-open baffle speaker where the baffle us a large folded tube that goes from about 3' high behind the speaker, down to the floor, doubles back, then back up to a large opening next to the speaker at 3' from the floor so it can be pushed up against the wall?

I have a question. If I go to calculate a speaker enclosure (Fs, vas, qts, and qtc of .707) and it comes out at something ridiculous like 200L (7 cubic feet) for a 6 - 8 inch woofer, by that point does it just make more sense to assume it's an 'open baffle' driver, rather than trying to build a 7 foot tall enclosure? Or do I try to squeeze it into something more reasonable like a 60L and just ruin the frequency response?

I swore I watched one of your baffle videos years back. I'm so glad you picked this up again anyways to talk some more. My house is finally ready to move back in and last night I just performed measurements on my 8x8" woofer array I built from the scraps while I've been trapped in this rental. I mostly want off axis cancellation to extend out for courtesy to my neighbors and I did the test and found a pretty awesome -6db dip @ 35hz and again @ 18hz ... Unfortunately it raises a little @ 28hz which is a popular tone for movies from my data Ive gathered on bass scenes. I'll test outside to verify my results but I have a 6" side wall to balance the wood up there but it only extends to the rear. On that note if no one bothered reading this far I'm gonna ask a question in a new comment. ...Can I center the side walls around the middle of the board and maintain proportional dispersion at the front and back and therefore get a perfect 90* off axis cancel again....I think right now with my side board extending from the front to back it's turning more cardoid

Are you asking if you can make your woofer section into more of a U shaped baffle?

@littlegandhi1199 3 жыл бұрын

@@dannyrichie9743 Thanks for replying to my ramblings! I've attached photos of my current build. I haven't taken it outside to measure it yet but I assume since I have a long wall (which I only put up to balance the thing) only on the backside that it should produce an uneven cancellation pattern. Not 90* off-axis but somewhere further towards the back? So it's 6 inches but here's the pictures of my designs. imgur.com/a/mBXDVWd Can't I split the difference and put 3 inches in front and 3 inches behind to restore the perfect 90* null both ways? I'm going to investigate steel pipes to keep the weight up so I can maintain a completely flat board too but in the meantime would this do what i think?

@dannyrichie9743 3 жыл бұрын

@@littlegandhi1199 The H frame and U frame design both separate the front and back wave the same. If the side panels are the same length then the separation is the same. The issue with a U shape is that it puts a ton of pressure in that U shaped area. So you have to add lots of bracing to support those side panels to keep them from resonating. You will need a brace between each woofer and another inline with each woofer. An H frame splits the panel up so that you have less panel area to resonate. So with just a brace between each one it is not near as bad.

@@dannyrichie9743 H frame is alternating direction.the woofer faces right (forward/backward) and wire it out of phase? Can I use my remaining 8 woofers and build a 2nd stack and face it backwards (and attach it to the wall of the first one) to the same effect of lowering bass extension? This is what I read H frame is capable of doing and increasing directionality further to the front and back as well...

The passive parts had MUCH less of a negative effect on the sound and was never a limiting factor of the performance. The all digital solution did not sound as good and was always the limiting factor to performance. Differences in the D/A conversion, power supplies, A/C noise, and multiple cables are far greater performance limiting factors and had a much wider degree of variance than the passive filter parts.
