GEAR Upgrade mods. because all audio gear vibrate and produce negative resonance

I have a set of Mission V60 speakers (75 dollars used) put self adhesive sorbothane duro 70 around the plastic that hold the tweeter and the woofer, And my sound is extraordinary good and detailed, but i have made a cheap room treatment with diverse thickness of pieces of foam...Now upgrading is impossible, except to pay more than one tousand new or many more dollars used, but with which speakers can i beat what i have now?

 

i have already purchase a sub miller and kreisel, but i will sell it, after sorbothanized my speakers properly, no need for a sub, i dont have sub-bass, but i dont need them now, the bass i have is satisfying....In fact the sound is so detailed, imaging so good, that it is better than my 2 headphones, he 400 (+sorbothane) and Stax SR-5 gold (+sorbothane), and my he 400 is now so good with the grill mods and the sorb. that there is no comparison between them new and now...Upgrading the Mission now is appealling but with what ? And what will be the cost?

For the 3 years i wander across all thread about audio products, i hear only review and impressions of people in need of more always more costlier products... The only useful thread i read was about sorbothane and room treatment...Now my system is so good than i am afraid to upgrade...I wisk when i was a new guy on this hobby someone would have told me , buy some good basic product like the one i have or some others also good, and now use sorbothane on all your gear, and room treatment, after that enjoy what you have...

Yes it is 60 hertz , but a clear, dynamic 60 hertz is better than a muddy 40 hertz, trust me...

 

i have never said that my mission are superior to all one thousand dollars new speakers...The title of this thread is not mine but yours, i have nerver created this thread, but now i have correct the title to my own liking, thanks to you for the idea of this thread now ....I only said to someone that with appropriate mods(sorb+room treatment) these speakers delivers instrumental timbre naturally , and when you have a natural sound why search for more? ...I dream about upgrading, yes like all of audio people, but with what and at what cost? ... My original post was not an affirmation about one thousand dollars speakers PER SE but a subjective affirmation about this upgrading effect of mine, it was a suggestion to someone post about sorbothane and room treatment that transform ordinary speakers in extraordinary one, hence my post were not asking anything particular, just describing my thoughts and experience ...For the subbass i dont need it ...My Mission deliver 60 hertz very clean and hard... the orginal Mission msrp is 580 dollars, i think that these Mission +mods+room treatment compete with many speakers around one thousands without sorb. and without room treatment , yes and this is my point...If i want to upgrade now, my point is if i want to be sure that this will not be a sidegrade, one thousand dollars speakers is on my mind...By the way try to put sorb. duro 70 around your speakers tweeters and woofers and you will be pleased...ALL audio gear vibrate that will be my title thread if i have to start one...

 

like the title now said : speakers upgrade mods, mine consist in self-glued 70 duro sorbothane pieces around the tweeter and woofer, not on the membrane for sure, but around it.... It is good also to isolate the speakers from the room wall or floor with sorbothane 70 duro under it... i have put a load (granite plate on top of mine ) that make audible difference in suppressing some vibrations, and i adjust the exact load by listening, and choosing a heavier or lighter load ...With only that the Mission speakers sound now exceed is original sound with a great improvement....All speakers enclosure create negative resonance that feed back to the membrane own resonance, destructing the clarity of the timbre and sound...Sorbothane not only like many product isolate the enclosure, but most importantly absorb vibrations and transform rapidly them in heat, diminushinng hence the negative resonance with the membrane of the tweeters and woofers...It is my explanation, but i am by no way an engineer or a scientist...The absorption and diffusion properties of sorb are part of the sorbothane original designer intention, not my idea...

For the room treatment this is very effective, without paying big money, I had made mine with diiferent grade of compressed foam, on the wall and on the ceiling, listening each day for a week and with each different grade of foam at different place, all room are different but it is easy to try and experiment....All the foam cost me 50 dollars all in all...

These two mods made a bigger improvement than all my gear swap for the last 3 years.... Many speakers, amp, dac headphones change for the last 3 years....Hence before giving money after some reviewer have said something in his analysis of new gear, try to improve your owns...By the way the better way to upgrade an amplifier if possible is to pay small money to a vintage one....i own a sansui au 7700 that cost me 200 hundred + catalytrics changed, the sound is so good of this amplifier that it is impossible to beat that unless to pay multiple of this price.... The sansui was top of the hill audio in 1975...His sound is sweet like tube but not muddy at all crisp and punchy...

 

«your post is very vague»

My first post is vague here because it is out of his context, because it was a response to a post in another thread (not a mixed question in itself like you said), and you create suddenly a new thread for me , thanks to you, my last posts are clarifying that ...thank you for your intervention ... i think that these 2 mods will be interesting for all to know and experiment...

 

A few of us experienced these at the last THE Irvine and I for one was impressed by the difference it makes. No brainer upgrade for those of us who put our speakers on desks.

 

@OJneg: From my own, vastly more limited experience, those are pretty great. Worked better than I thought they would, honestly.

 

Very interesting indeed.... But speakers stands dont absorb vibrations and does not transform them into heat, sorbothane is a visco-elastic polymer whose application reduce the effects of the negative resonance from the enclosure and vibrating membrane, hence sorbothane dont only isolate the speakers from the desk...That is the point of using sorbothane also around the vibrating membrane, it is for not only isolating but erasing negative resonance of the internal enclosure and vibrating internal parts resonance ....

Anyway good beautiful stands are great improvement because their isolation of the speakers from the floor will enhance the sound for sure but neither they will absorb the internal vibrations inside the enclosure of the speakers, nor they will isolate the membrane vibration from the vibrating enclosure from ...

.My speakers are on my desk and i place each one of them on top of two square granite plate with sorbothane between them , and that completely isolate them from the desk, and the total heights is one inches, with these stands my speakers would be perhaps too high for my ears, even at three inches ( the tweeter of mission speakers is under the woofer and must be few inches under the ear), and the price is 100 dollars, the sorbothane way less costlier with the 4 granite plate costs added to 40 dollars in all for this isolation...For sure i like these stands and i trust the many reviews that they are good for what they are created for : isolating vibrations between speakers and desk or floor...But my solution seems better...

 

almost as classy as stacking three reams of inkjet paper under your desk speakers like I do

 

i will like to buy some classy sorbothane stands, but i fear the price would be more than one hundred bucks...Hence i prefer to make that works by myself..But i must admit that your 3 reams of inkjet papers are too much "classy" for my taste ...

 

this is a pretty nice explanation of the design of the isoacoustics

 

I use stacks of inferior components that I can't sell as my speaker stands...

 

It is like the point i made is drowned under the "stands facts"....Cosmetics is good, and a good stand is a good thing.... but the point is Sorbothane is not cosmetic or for standing speakers or only isolation purpose ...I will repeat myself here : sorbothane is a visco-elastic polymer whose application reduce the effects of the negative resonance from the enclosure and vibrating membrane, hence sorbothane dont only isolate the speakers from the desk...

i think someone can put a Stands thread in action now ...


the 2 granite plate with sorbothane in between, under my amp, is the same i put under my speakers : it is their "stands" on my desk...
