Eminent Technology ET-2 Tonearm Owners



Where are you? What mods have you done ?

I have been using these ET2's for over 9 years now.
I am still figuring them out and learning from them. They can be modified in so many ways. Bruce Thigpen laid down the GENIUS behind this tonearm over 20 years ago. Some of you have owned them for over 20 years !

Tell us your secrets.

New owners – what questions do you have ?

We may even be able to coax Bruce to post here. :^)

There are so many modifications that can be done.

Dressing of the wire with this arm is critical to get optimum sonics along with proper counterweight setup.

Let me start it off.

Please tell us what you have found to be the best wire for the ET-2 tonearm ? One that is pliable/doesn’t crink or curl. Whats the best way of dressing it so it doesn’t impact the arm. Through the spindle - Over the manifold - Below manifold ? What have you come up with ?

If you guys recall, there was mention a while back on this thread that Bruce and his team were going to Africa with the BBC to test the hearing of Elephants using his TRW - 17 Rotary Sub. I've noticed some really cool pictures and footage of the trip to Africa have been uploaded to his rotary woofer website. I've linked them here.

Bruce' team then went with the BBC to Florida to do testing with alligators.

Happy and safe New Year to everyone.
Dear ct0517: One critical subject in the sound generated by any subwoofer is that we at home need enough cubic area for the bass soundwave can be in real way developed, if that cubic area does not exist any one can't " hear "/ feel a 5 hz soundwave. We need " hundred of m. to those very low bass sounwafes really be formed.

Yes the ET unit is something really different of what we normal mortal audiophiles know.

Very good links.

Regards and enjoy the music,

Hello Raul - Feliz año nuevo and welcome to the thread.
If I may make some comments to your post.

Yes, I agree you can't defy physics when it comes to bass especially when someone is making a Subwoofer inside a BOX (enclosure) and placing it in a larger box "the room". One of the latest audiophile darlings.

The Gotham by JL Audio

reproduces 19hz - 200hz (+-) 3db
Dimensions* (H x W x D):
34.13 in. x 21.50 in. x 24.00 in.
867 mm x 546 mm x 610 mm
360 lbs. (163 kg)
$12,000 plus $3500 for the crossover. US dollars.

Now in regards to this ET Rotary Subwoofer - it is thinking "outside of the box" and it is designed to take over where that JL Audio Gotham stops producing below 20hz. It uses that "extra room in a persons house" meaning , the basement, the attic, side room that the rotary woofer gets installed in - the room, space itself becomes the BOX - the infinite baffle ....the sealed enclosure.....

So who is the customer for this? This rotary woofer is now being used in theme park attractions, concert venues, professional audio applications and research projects. But I think there are also possible clients for this product right here at Audiogon. Any potential customer for a start would need to have $12,000 US dollars for the Rotary Woofer which is similar to the JL Audio Gotham price. But from there an additional $8k -$12k for the design and installation. So approx $20k - $25K US dollars total which includes crossover and external amp. And of course this person (client) has a house with the space available for the installation of the Rotary Woofer to create this infinite baffle.

For this, the person gets to hear and feel "the 11hz hertz fundamental frequency from a helicopter rotor, the low frequency rumble of wind, the space of a concert hall or infrasonic information contained in an explosion." taken from the website.

Well this client is not me.
But let us just imagine; this "guy" male customer (no woman would do such a thing right? ) but .......imagine this guys wife, spouse, better half coming home to see the inside walls of their beloved home doing this.

the above is from the Africa segment linked earlier. I got a good laugh - the video shows outside the van containing the Rotary Woofer working inside the van to attract the Elephants.

And from that link's description.

"With the rotary woofer playing a thunderstorm recording, the elephants all stopped eating and turned toward the camper van."


Cheers

My 21 year old son sent me a couple links today. I think inspired by his girlfriend.....     
I started laughing when I opened them up and I thought for a moment, maybe there is some hope for him ?

had to post.

Indecent Proposal - Robert Redford - TNT turntable and ET 2.0

My son always liked my old TNT - told me it looked like a tarantula spider.
Black is beautiful.

When Bruce told me he was going to be making parts in aluminum I thought for a second maybe he was about to add some bling to the ET 2 tonearm in the form of shiny aluminum. But he stayed true to his low key self with the blacked out aluminum mounting plate.    

ET 2 owners - notice the correct placement of weights for bass in the first link..

Anyone know what the cartridge is in the second link.....a Benz ?


Happy Listening
Dear ct0517: Yes, I remember the first time that I saw that very good picture and was my wife who took my attention about.

Obviously that tha beautiful house is a house where the owner likes music and know what this means in a home audio system ( I'm talking not of RR but the real owner. ).

IMHO, the ET tonearm is today an icon/sign in the audio history.

Regards and enjoy the music,
