mahgister Very Interesting, I also have, years ago, a small platic cube, with a hole, fix to the back of my speakers and only just a half inch, up or down the back of the speaker would transform the sound ! May be You should post a video on YouTube: Helmholtz Bottle with straw. Thank you
Helmhotz resonators for audiophile at almost no cost and without calculus...
The importance to treat the room if you have speakers, even in nearfield listening like me, is imperative ...
Here is my advice:
Buy some big empty wine bottles, or drink them before, it is optional....Or use some carafes, the kind that some display at the center of a table....I use plastic wrapping sheets to tightly seal the aperture of the bottles and the carafes after pouring in them around 10 % of water in their volume space...You must listen and experiment for your taste and room to determine the exact amount of water to boost the frequencies that will benefit….After that I peirce the plastic sheet with a needle and I insert a thin straw with only the extremity of the straw at the top... That its! You know have an Helhmotz resonator...
You now have one of the more astounding tweak for a room that will transform your listening space in sound heaven ...I use more than 15 of them in my little audio room and trust me that is one of a kind upgrading...
I wrote that for those who want to experiment, the others can stay silent...My best to all...

mahgister, I don't think there is anything wrong with your method, so I hope you didn't take it that way. My only problem with the straw was the hole diameter being to large for the results I was looking for. I have a small metal working machine shop in my basement so all I'm doing is machining caps (or plugs) for the bottles & drilling a .125 hole (1/8") in the solid cap then placing a chamfer on both ends of the hole. The chamfer is about 60 degrees and approx. .100 deep & should help the air move in and out of the bottle a little more efficiently. Total length of the cap is about 1.5" to 2" long. It also appears that the fat bottom long neck bottles work best, as you already discovered. Hope this helps. |
