Eminent Technology ET-2 Tonearm Owners

I always thought the best tweaks for when curious or bored were the free ones. Harry, you have a nice sized space from your virtual system. What HZ do you have your speakers crossed over to the sub ? If they are crossed below 100hz, you have the option of running your sub near field.

Your sub will work 1/4 as hard, there will be less heat and vibration so its  components will last longer; but most important, the bass performance will increase multiple times better.

Now, I realize it is not doable solution in some rooms due to aesthetics or having the sub cables running across the room. Still for giggles .....
IMO anyone running one sub or two should experience this at least one time. Regardless of how much and the type of bass each of us prefer in our rooms; I think its the bass that will make or break the room in the end. 
 
Remember to change the sub phase to 180 if anyone wants to try this. To ensure it is running in proper phase I like to place my hand on the subs cone surrounds and feel the pulses to ensure they are in sync with the bass notes from the main speakers across the room,

Cheers Chris

Wisa pump isolation o-ring info here:

https://forum.audiogon.com/discussions/wisa-audio-pump-for-et2-tonearm/post?postid=1681632#1681632

reading through that info....

If the WISA pumps design, produced enough case vibration to wear out its footings, this means it is also sending noise down the air line to the air bearing chamber. Why not hang - suspend, the thing in the air like the tonearm, and be done with it ? Think outside the box.

I can think of a couple a ways to do it if I owned it.

Just saying.

Hi Chris,
They "wear out" due to age.  They get hard and crack.  Putting the pump in another room is the easiest way to mitigate vibrations.  An even better way is to use a large air compressor to get rid or the air pulses, but that's a different matter altogether.  The info in the link above is for someone wanting to bring their pump back to factory configuration and operation.

"wear out due to age"

Oh I realize that Ketchup. Firstly my apologies for going audiophile on you guys..temporarily. The recent chill in the air has forced me inside. Must be the contributing factor.
    
I said what I said because I thought hanging a pump motor would "improve" on the set up. Another way is to add the surge tank - yes.

"Putting the pump in another room is the easiest way to mitigate vibrations"

It's still sending noise down the air line like electricity.
So a very easy way of finding out how much noise for those interested. (Discussed here already)  

If one wants to find out how much pump noise is being sent down the air line follow this procedure.

******************

1) With pump on and system muted - Lower the ET2 onto a still record.
2) Turn off the air pump.
3) Still muted turn the volume up to regular listening level and Unmute the system.
4) Place your ear next to the speaker.
5) Have a friend/wife turn the pump on while you listen to the speaker. Note any differences.

So it would be an interesting comparison with a standard WISA setup and a hanging one. anyways. 

ps.

6) One can also start jumping up and down around the turntable after #5, and, if  there is no noise out of the speakers..... your setup is solid.

Ok.... will turn audiophile mode off now. 8^0
