Equalizer in a Hi Fi system

@mahgister I would, personally, like to see a picture of your acoustical straw thing!

And, I say:  f#&k those who don't have respect for your ingenuity! ... I do.

And I'm quite certain that there are many Lurkersout there, that really dig it, too, because I was one of them for years before I becamse brave enough to even comment. ha ha ha ha 

What stimulating conversation.      : )

@mahgister will you post that picture, please?

Sorry but i dont post any image of my system here anymore ...

But i will explain to you with photos what you must not do ...

here you have two images of what you must not do ..

The bundle of straws must be of different lenght or different volume ... You tune your speakers by ears to fine tune the needed volume/neck lenght ratio as with the Helmholtz resonators mathematical formulas but no computing is needed if you use your ears ...Mine had in this bundle of 17 straws 2 set of straws for example each set consist of 3 strwas inserted in one another almost 2 feet lenght behind the speaker ... Some others straws are shorter and longer than normal straws ... You play with the lenght and tune by ears ... Very easy and fun... My hertz extension go from 80 hertz now to 50 with no boominess and no impeding resonance as it was the case without this redesigned porthole .....Pick foldable straws by the way to help break the main resonance in smaller one , then use the complete straws or if you cut it the foldable parts ...experiment it is fun and paid a lot acoustically ...

I was harassed non stop by idiots here for years with some openly mocking in the regular threads not only in the comments with photos of my "crazy" unesthetical room ... And i never dare to put my 100 resonators in any photos by chance because it was too much ...😁

Now i lived with smaller speaker in my acoustic corner ...i put standard image of my components not of my room sorry ...No need for an image whit what i just described anyway ...

And please try to understand my position ...

By the way this idea comme from a speaker designer very knownnot from myself the "tin foil hat" for some here  :

Neville Theile

«In these enclosures, the rear radiation is utilised to boost the bass response below the loudspeaker driver’s resonant frequency. The combination of the enclosure volume and the vent length and diameter form a Helmholtz resonator, which (when done properly) reinforces the low frequency response without creating excessive bass and/or poor transient response.»

@mahgister oh Dang! on my request

I guess my skin is thicker than yours?        : )

I just described what not to do with images...

I described what to do with words ... It is so simple that you dont need an image of my speakers ...

And my skin is thick but when troll hurt the same spot for years even crocodile skin reacted to this after few years ...

I am not a crocodile ...

If you want the right way to do my experiment i described it exactly ...

If you want only image of my speakers porthole by curiosity i am sorry ...😁😉😊
