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...

Ok after the carafes + thin normal straw, described in a precedent post.... I experiment also this after-noon with a big 5 gallons empy plastic jerrycan for oil with less than 10 % water in it+ a large plastic straw for slush glued to another one, inserted trough the plastic wrap paper sealing the nozzle of this jerrycan and guess what?

The bass was improved to the limit of my speakers with clarity without compromising the effect of my other generators on the other sound frequencies... Really amazing, almost no cost...This Helmholtz resonator are the second most amazing tweak of my life...

The carafes and the jerrycan act complementarily on different sound frequencies without obstructing one another to my ears...Stupendous, it is like I upgraded my speakers that now go way more lower in bass without loosing nothing but with gain on clarity on all frequencies...I apologize for my bewilderment...

I add a 2 gallons+2 thin straws this time glued to one another inserted through the nozzle... Result: more clarity in medium especially... I put this one near the wall behind my listening position...Bewilderment does not diminish,but I think now that I had touch the end of the road with these resonators...My best to all ...

I'm shocked you can put that many in your room. I put 5 in my room & it made the sound very thin. It provides better detail but sucks the life out of it. Yes, I've messed with location, opening size, throat length & the amount of water. I did find 2 spots in the room where it made the best difference, so I'm down to 2 of them with very small openings. I have several pounds of quartz on the walls & am thinking the 2 methods are not playing well together. Not done messing around with this yet though. No doubt it makes a difference, just not sure I like it...

Try the jerrican 5 gallons with 2 slush large straws inserted in one another and placed in the pierced  plastic sealed nozzle, that will equilibrate the frequencies toward the bass I promise... Just a little water in the jerrycan less than 10 %....It makes wonder all these resonators and by the way I use 20 types of stones and crystals in a connected grid on my audio system and in my electrical grid...All that push my system each times to more quality... But now it is I think impossible to makes all that I have sound better...

In audio price is not linearly connected to quality sound …. Tweaking already hi-fi used or vintage pieces of gear is the key to paradise...The Helmoltz resonators is astounding, but with some experiments...
