Cheap Isolation fix - Vast Improvement

Recommended Posts

If you raise any speaker of the floor or surface and use a stand, it's going to sound less boomy.  You can hear that difference even on an iPad speaker

I have cut these into quarters to replace the rubber or plastic feet under the electronics.  I feel they would be much better than plastic or rubber which has hardened over time. 

I do note that these squares are promoted for use with heavy equipment that has obvious vibrations (eg. washing machine), the anti-vibration may be less effective for lighter loads (electronics).  Still, at this price there is virtually nothing to loose from experimenting with them.

Yeah, the smaller ones are of greater density in structure compared to the 100mm x 100mm ones.

They turned out well.  I used a 10mm spade drill bit to create a recess for the bolt/washer. 

A full-size one can be used with four bolts securing them to the chassis.

Just got back from Bunnigs with 2 packs of the 100 x 100 pads .

Put 3 under my TT and am going to cut the spare into 4 for my preamp.

Question : - l have my rack sitting on carpet over the old wooden floorboards, no spikes. Would these pads help if l put them under the rack?

 

Well a brief listen to a few favourite tracks today with the pads under my TT and preamp was a little strang.

First thing that had me a little stunned (l wasnt expecting to hear much change straight away) was what l thought was a slight lack of bass - could it be that the bass was presented more cleanly, with less mudiness?

Also, even more noticeable was the higher frequencies which seem to reach higher and cleaner with seperation that im sure l dont usually hear.   l put that down as a result of the bass being cleand up.

l dont usually believe a lot of these reports of cheap and easy tweeks that CAN improve the listening experiece, but these little pads sure have done something to my setup

Under the Rock, seems to make the sound a bit lighter, but then again the PHO-8 is still running in too.

Under the Luxman, have not tried it yet.

It's a little confusing at first isn't it, I have to work out a similar thing when i placed bamboo boards under my speaker stands, the bass  seemed to disappear at first! but it was just that the muddiness was gone.

Bass is still there, the PHO tightened that up.

Been reading this thread with great interest. But I am a little confused.

 

I have floorstanders on carpet (with a garage underneath).

Should I be putting my speakers on spikes or bamboo or those isolations pads from bunnings? 

 

If my question does not belong here then I apologise.

I'm in a carpeted unit with garage under concrete slab, I found best result to my ears was spiking the stands of my ML-1's and placing them on bamboo boards. At first there seemed a noticeable reduction in bass, but it was in fact that the bass had become more accurate, at least this is to my ears.

 

Floorstanders are akin to standmounts on stands the way I see things.

 

Not an expensive path to try either.

 

I only use the anti-vibration stuff under component platforms, in my case bamboo again, and under the feet of my equipment rack.

 

Works for me anyway.

Try both and see which sounds best to your ears with your system.  It's the only sure fire way of knowing which will sound better.  Both tweaks are so cheap you've got very little to lose by experimenting.

Went to Bunnings myself for some Vermiculite, found these in my trolley......

Going under the vintage Wharfedales.

Have they helped your sound?

Too many variables to tell, just swapped cart, phono and these slipped into the system.

They do however protect the surfaces my gear sits on :)

Cheap and easy tweaks can fall into two areas:

1.  Cheap and easy tweaks that actually work (for most people, they are dependent on the equipment and setup you have)

2.  Cheap and easy tweaks that don't work and are just designed as an elaborate prank by some to demonstrate how gullible audiophiles are.

 

My preferred version is the first.  In many cases it's easy to see which version you are dealing with.  At other times it can be difficult to differentiate the two varieties without trying, with the risk of egg on your face.

This is why I try to make only one change at a time, all too often I have made too many changes at once to really understand what each has brought to the table.

 

Although I do like that they protect the carpet with the ones under the threaded rods in my rack :cool:

The spikes stop the speaker boxes from moving on a soft surface in response to the movement of the drivers (Newton's Third Law).

Isolation pads stop the promulgation of speaker box vibration to the floor and from floor to speaker box. 

Both may be of use.

...I might have been satisfied with my AVR’s sound had I just isolated everything in the first place and went from there. And though I’m happy I have that power amp, I think I’d have been happier setting things right up in the first place.

 

Out of respect to the store that sold me the gear in the first place, I want to note that after running the system post isolation of speakers and components- but without the power amp, I'm most definitely not happy with the sound with the avr on its own. It does movies and tv rather sweetly but true two channel hifi just isn't its forte. The power amp lifts things into a new dimension- as it should I suppose.

Well blow me down with with a feather.  Just tried this little "hack" and it has made a difference.

 

I put the small blocks under amp, DAC and CD player. Everything just seems a little tighter and more defined.

I have to say thanks to ArneS. What a difference!
I have wooden floorboards and a tt on a sideboard. On my travels today I decided to stop at Bunnings on my way home and see if any improvement could be made. The first was to try the tt, which was hard to tell if the sound had tightened up, so I continued next to the speakers. Wow what a difference, the bass was tighter and the highs were more defined, but I was also hearing some sort of distortion on the highs, like it was over defined. It just didn't sound right, so I thought I might lower the VTA on the tonearm as I knew I had it slightly raised and what do you know the distortion disappeared.

 

The only thing I can think of is that I had the VTA slightly higher to compensate for the bass sounding slightly boomy when it was lower. The sound quality by using the vibration pads has made a very noticeable improvement, especially on wooden floors. Without a doubt great bang for buck improvement, will continue and try other components and see how that goes.:)

Pleased to hear you gents have had some wins. To me it was really easy to hear the improvement. For those with racks and speaker spikes already, I'm not sure how helpful doing this sort of tweak will be - but if like me all you were doing was sitting your speakers on the floor, and components directly on shelves - it's a cheap way to get some big improvements.  No brainer.

Both may be of use.

If using both solution, then there might be a need to add another solid substrate between spikes and anti-vibration pads. Possibly an inert stone or wood.

      Item: Trevor Lees Floor standing speakers
      Location: Point Cook 3030
      Price: $150
      Item Condition: Used
      Reason for selling: suit someone with better skills than me
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info: bought these off another member in poor condition both the cabinets and drivers. They cost a heap more than what I'm now selling for. I have since spent many hours and money getting these going again including a restore on the cabinets themselves. 
      I have replaced all the foam surrounds, dust caps around the drivers and inspected the crossovers and resecured etc. Got the speakers working again but I then broke on wire to the voice coil of one of the drivers (check photo) so I'm over these now.
      An easy fix for someone with the ability. Or a new replacement drive is about $120 local which makes these still crazy cheap. Cabinets are good in condition and this is a quick fix to get a Proac sound. 
      No grills.
