$999 DIY Baffle holding its own against $10K Hifi versions!?!? 🤯🤯

[@LordShad0w.162]

A solution to your issue with the screws is to cut a ring and glue it up on the back. THis gives you plenty of meat to screw into as well as allowing you to route a nicer bevel in that pulls all the way down to the driver rim. :) Also if you ever want a fast, beautiful finish that is literally a wipe on wipe off affair, use Danish Oil. You can even tint it for a nice range of colors. Either way, very nice job my friend!

[@abxaudiophiles]

Great idea!!! Thanks for sharing

[@ronniecramer1252]

I have no doubt that your baffles sound great. I discovered in the past that you can take almost any single full range driver, put in in a piece of plywood, and set it 3-4 feet from the front wall . It will outperform most over the counter speakers in 3-4K range. My latest setup consist of Eminence Alpha 15 in. woofers in the bottom, and 8 in. Tang Band full range up top . The baffles are 22 X 38. I'm driving the bottom with a pair of Maraschino Cherry monos {250 WPC} and a push pull 7 watt tube amp driving the top. The absolute biggest Improvement in the sound came when I replaced the passive crossover with a Marchand electronic one with a 250 Hz. setting. I would put these up against anything i've heard in that 10grand range. I bought the Tang bands and the Marchand used. I have approx. $1200 total in everything. I'm retired now and sometimes listen to this setup for 10-12 hrs straight.

[@christianrintelen]

the beauty of open baffle is no box coloration… you could still add some dampening material to the back of the baffle. or use marine grade plywood - the loaded bass driver *will* put some vibration into the baffle. i would probably have split the baffles for the 18" and the 15" so that the 18" will only rattle it's own baffle (more about this later). the width of the baffle will have a big influence on the bass quality - remember, the bass driver will put the same amount of energy towards the back but in opposite phase. the front and the back wave will eventually meet and cancel each other at all frequencies where the signal is exactely in opposite phase. the wider the baffle, the less cancellation. on old Voice of the Theatre speakers, they often added wings on piano hinges to add bass oomph. one important thing: don't worry about rigidity; our drivers do give enough structural rigidity. what you *should* be concerned with is bracing the panels so they can not move back and forward. you want the driver push air forward into the room and not the speaker baffle backwards, as newton's law of actio est reactio would predict… imagine a 15" driver suspended by nothing but some thin rope from the ceiling. now do a sweep with low frequency sines from 20 to 200 Hz at high SPL. you will notice that the driver will start to swing back and forth and the more it does so, the softer the sound will get - if the resistance of the air is higher than the inertia of the speaker, the bass energy will not move through the air, but instead push the speaker backwards. this not only lowers the efficiency, but it also smears up the sound. you won't notice this until you really brace the baffle so it cannot move at all. the foot of your speaker is way to small to prevent the top heavy baffle from rocking - and yet, you did hear an improvement when you re-seated the baffle from the front of the foot (where it could freely move forwards when it was pushed from behind by a positive rear wave) to the middle. however, with the 15" driver mounted so high up, you would ideally brace the baffle from it's upper edge both, to the back and the front with diagonal struts. i know, this makes the baffles an eye sore and you'll constantly trip across the front mounted struts - but i guarantee you that you will be … uh … baffled by the improvement. instead of bracing it with diagonal struts, you could also brace it against the ceiling. (eg with two vertical 1" aluminum tubes that screw into the upper edge of the baffle and into a threaded plate mounted to the ceiling. yes - this makes your speakers kinda immobile, but that's actually what you want with open baffles. there's no free lunch…) bracing the baffles to the ceiling also ensures they are really in a right angle to the floor i.e. you're actually hearing the frequency band of the midrange/tweeter driver on axis (where it's usually the flattest))

[@Justwantahover]

If you want a cheap alternative, build speakers with open cone FR driver plus boxed woofer (or 15"open baffle woofer). Run a 5" open FR driver on top of the box and a woofer in the box. Or with the completely open FR driver on top of the baffle. Also cut 8mm slits near and around the center (for the best treble in the worldl! I even have cutaways on the cone to act like a free edge cone (about 3" diameter). But this is not for the faint hearted! Imagine a circle 3" diam on the 5" cone. I made 5 one inch cuts around the circle with gaps that are not cut. Then I made curved cuts from the partial circular cuts, cuts running outside the circle, forming thin banana cutout shapes 4 mm wide at the widest. This makes the cleanest med range you will ever hear! They sound like panel speakers and it's so cheap. I used $40 boxed woofers and $10 5" FR drivers. And an inductor and small resistor on the woofer. The 5" FR driver can be hooked straight up (or you could use a mild filter). The cutaways tend to equilize it (along with the woofer to warm up the sound). The best speakers I heard and holographic off the scale! 😅

[@Entitaet69]

@@Justwantahover What you describe is exactly the way polish Qualio Audio are going with their "Qualio IQ" semi open baffle speakers which they presented last year. A boxed 9,5" woofer with an acrylic baffle on top with a 6,5" midrange driver and an AMT tweeter. The woofer goes up to 600 Hz, the midrange driver performs as full range up to 15 kHz and the AMT serves as an additional super tweeter covering all frequencies above 8 kHz which adds some kind of airiness to the 3D-like holographic soundstage. Since all drivers and crossover components can be purchased off-shelf for about 1.500 € I really think about starting my very first DIY project instead of purchasing a pair of Qualio IQs for about 7.000 € or even the upgrade version for 10k ......

[@garthdev]

Sounds fabulous and this has got me thinking would you want the baffle to resonate or not. Some speakers are designed to resonant and some aren't. We all know there is a product called sorbothane which is horrendously expensive but does work miracles in absorbing vibration. However there is a really cheap product that you paint on that does the same thing yet costs nothing compared to sorbothane. It's called decidamp 150 and you paint a light layer of this on to your wood it almost totally get's rid of any ringing..It's flipping awesome and would be worth some experimentation!!!!

[@abxaudiophiles]

We are actually discussing all of that in our discord currently!! Great conversations. Separate bass baffles are cool too

[@VEC7ORlt]

Pretty cool project, some things tho - you'd want a proper xo between the compression driver and your bass unit - you don't want to excite those cone breakup artefacts on the upper end - not a lot of drivers are well behaved in that regard. Cap only xo - idk - that will stress the driver a bit, but depends on the power level. Opening the rear of the compression driver is huge no-no - rear chamber is needed for proper loading and acoustic impedance matching, so response, distortion figures will be all over the place. Also flush mounting from the front is better - no surface discontinuity, compared to a chamfer.

[@abxaudiophiles]

All possible approaches and considerations. I think sometimes we like to as audiophiles create roadblocks where there really no “significant” issues. All valid perspectives for sure. 👍🏼.

How did those baffles sound with the lii song f15s you showed part way through the video?

[@abxaudiophiles]

The lii drivers are cool. Vocal rich, limited on full range.

[@andyeighttre]

Be interested in how these sound with Lii W 18 and a GR Research Triple Threat. I’m an old school EDM(barf acronym) that loves bass, and OB speakers with their lightning response and reflex make for epic living room dance parties. Great video!

[@mfkhometheater7742]

I don't doubt that they sound better than any commercially available conventional box speaker. I started building open baffle in 1994 and I don't know of any conventional box speaker I could enjoy listening to. Open baffle has a lot of advantages such as inherently more uniform polar response and virtual elimination of cabinet resonance issues. They don't have to have lean bass, it all depends on how you EQ them and on whether you have sufficient volume displacement. They can be designed to be bass heavy if you like. Either way, lean or heavy bass, the open baffle bass will always sound more natural than any box design. Great video about a really nice project, keep up the good work and always stay outside the box;-)

Totally!!

how to make good solid bass with open baffle?

Follow the guidance in the video. Check us out at abxaudiophiles.org for all the videos and info. 😉😁😁👍🏼👍🏼

[@DesignVisStudios]

Drop the passive cross over, put in a couple of digital amps like Hypex, set a basic fairly steep cross over in the amp, and time alignment in there too, and tune it with dirac or similar room correction.. Super easy to do and you'll have giant killers. I would use the Eminence Textreme carbon compression driver.

[@abxaudiophiles]

Lots of options. 😉

Nice - a 'baltic' birch would be a further improvement and it looks good on the end grain (many more laminations) though is about twice the price.

[@abxaudiophiles]

I’m not sure the baffle materials really matter that much more than size and components. Doubt there would be an audible difference. We’ve messed with all kinds of materials.

Actually the Discord group developing this OB speaker based on some soon to be available drivers, is going to develop a bookshelf OB speaker with a frequency response below 50hz. And I am hopeful someone will dare us to try saying that it can't be done.

[@geoffreydebrito7934]

@@terrygesualdo9588 Fully open baffle? Regardless of how capable the woofer, the challenge is overcoming this; longer bass frequencies will wrap around the sides and cancel each other out.

[@terrygesualdo9588]

@@geoffreydebrito7934 Yes and that is what creates the radiation pattern or polar pattern, that is also somewhat frequency dependent. When you slot load, then the way coming from the front and back are different. I would have rather James did a vertical slot or a round slot, but he wanted to try a horizontal slot, And the odd thing is it is working and working very very well. Who would have known, and the measurements prove it is working, and close to the predictions. I did another driver yesterday and the same thing happened. But because I didn't calibrate some things, correctly I don't know exactly what is happening. From more recent experiments, it would appear the driver is more important than the baffle, its Q specifications seem to be more important to how the bass is working than the baffle itself.

[@19brendan80]

I'm sure the difference in sound between the baffles most likely has to do with wave cancelation. Wider baffles will generally sound better because they don't allow as much cancelation of lower frequencies. Every frequency has a specific wavelength. That and wider baffles most likely do a better job at projection of some frequencies. Also your distance (placement) from rear walls will also play into this. Maybe a smaller baffle wouldn't be so bad if it was brought further out into the room 🤷🏻‍♂️ who knows. I don't really know enough on the subject. That's why experimenting is fun. What really matters is how they sound and if you like them. Sounds like you do 😎. Enjoy!

[@abxaudiophiles]

Wider baffles dont sound better, they just sound different. Experimenting is fun, everyone should actually do it. 😉👊 awesome stuff.

The baffle may be acting like the sound board in a piano. The piano I owned had s rather thin sound board made out of a light weight wood. The second smaller baffle had two change: size and thickness. You may also want to experiment with more and less dense woods.
