Townshend Springs under Speakers

However, there was a step back in one of the main areas I’m most sensitive about: density and impact of the sound. This is an attribute I have worked to get in to my system. With the spring footers, the sound just got a bit too light and featherweight sounding, less dense, less impact and connection. It became a bit more "electrostatic like" in the experience. Also the tonal balance got a little too brilliant and light, less rich.

Thanks prof for your review...

Just a word to say that your description of the Springs boxes nobsound match completely my experience...
 But the effect you lived through with the springs is could be partally solved by the finetuning of the compressive force...In my experience even under 100 gram of difference between load and weight made a very audible difference... My load of concrete  on each speaker is near 80 pounds...

I said partially solved... To solve it completely I bought another set of 4 boxes spring for each speaker...


I  solved this problem at last  in lost of " density" by introducing another set of spring boxes under this very heavy fine tuned load of concrete on top of my speakers... The dissymmetric compressive force difference between the 2 sets of 4 boxes, under and on top of each speaker, decreasing some resonance, give to me complete satisfaction...

Cost= peanuts

Negative: the speakers being stable are not enough stable for a living room with young children tough....

My best to you....

mahgister,

Interesting solution!   It must be really sonically satisfying.


I'm sensitive to aesthetics in my set up, so would be very unlikely to employ such a tweak.

In fact I've been shedding gear.   Just sold off my subwoofers, crossover.The room looks (and sounds) better without them IMO. 


It's actually a relief to simply.

Though I'm not finished in the tweaky area of things.  I'm still doing ongoing comparisons of two amps, tube rolling etc.   But hopefully that will be over with soon and then back to just listening to the music.

I understand that my solution so effective it was cannot be adopted in a living room at all...

My problem was cost...

I dont wanted and never bought anything costly...

I prefered to use cheap materials and my homemade devices...With astounding results...





« A straw can change the sound of an entire room if you put it at the mouth of the rightfully choosen bottle or pipe»-Anonymus Acoustician son of Helmholtz

Helmholtz as in the Argent Room Lenses I recommended to you a couple years ago..Great devices they are...stage shifters and shapers. Tom

Precisely yes! i thank you for that in the past and i can thank you again...

But it takes me only few hours to understand why argent Room lenses are not so effective...reading about psycho acoustic and Helmholtz original ideas...

I created more than 40 Helmholtz tubes around my room and they begin their "circle" near the tweeter of one speaker ( few inches) the "head" of my mechanical equalizer and ended near at few inches also the woofer of the other speaker...

The reason for this is the psycho-acoustic fact linked to the way each ears perceive first frontwaves sounds coming from each speaker and the way the brain locate each sound in a room...

Then the power of my mechanichal equalizer compared to the Argent room lenses are huge improvement...Because the room lenses are not each one of them like my 40 tubes and pipes and bottles FINE TUNED each one in relation to the technical specificity of the speakers and the specific acoustic features of the room geometry, topology and content...Each of my tubes work differently in their particular location creating a new pressure zone in the room...

And my mechanical equalizer cost is zero...
I used only discarded plumbers pipes tubes and bottles... With straws of different size mechanically adjusted to the mouth of each pipe... More than that i also created tubes which are more diffusers of sound than absorbers...

All is fine tuned on a few months listening experiments process like we tune a piano....

Then yes it is you who inspire my idea but there is NO relation in cost and efficiency between my equalizer and the 9 identical tubes of the room lenses...You just put my attention at the right time on the right phenomenon : Helmholtz bottles....Thanks for that....

Because i never bought any tweak but prefer to let them inspire my own working i react speedily....

My geatest tubes is 8 feet high and the smaller one is almost a straw...

In audio nevermind the amplifier, the dac, or the speakers, ACOUSTIC is queen....

 For sure my mechanical equalizer cannot be put in a living room....

 The most precious tool for audiophile experience is simply a dedicated audio room... It was and is my own luxury in audio....
