You know the Twin Pulse project with double-drive Grado?

hai there..
 
long time no see 

 
 

 

 

[7keys]

it is a new prototype Spirit Labs that uses two drives connected in series. Load isobaric + resonance chamber. drive movements halved - piston movements faster and controlled mobile unit. in a very linear frequency response. warm sound and impressive dynamic at any volume.
load of 64 ohms easier for tube amps.

Why not put one out on tour so we can have a llisten? We put a SennGrado out on tour and it turned out pretty good, every one that wanted had a listen and wrote a review.

I wonder what the shipping costs would be? Would you want to extend the tour to all North America?

 

[AndreaRicci]

Shipment to United States costs 50 € Twin Pulse I then every beta tester will send out to the next.

Lovely stuff, I recognise Adhi's handiwork. I saw his black rod blocks, but what's with your gimbals? - did you paint or anodise them yourself, or did Rholupat supply them in black? Never seen them on his website, and yours look extremely handsome ...

I just don't see anyone wanting to spend $56usd to ship them back to you, otherwise I'd give it a go.

What Grado drivers are you using with this build?

 

[AndreaRicci]

$ 56 one time for it to arrive in the United States, then it getting through you. Use drive series "e" with three holes.

Just finished this:
 

 

 

First impressions compared to the ypsilon, a bit warmer, highs are not as extended, more forgiving of subpar recordings.  Will let then play for a while before judging them again.

Is that a custom ImpactAudioCable?
 
I'll be putting together my build soon, just need to decide on the cable.

Grado RS-1i completely recabled with 20 feet of Cardas. The guy who did the recabling did a swell job of it but this is a mod that is not recommended for the average tinkerer. There is some risk that the wooden bodies will sustain damage in the ungluing and/or reassembly phase...

Pics?
 
I have heard much weeping and wailing over attempted RS1 re-cables. It takes a high level of skill to extract the drivers without damaging them or the cups...

@DavidA
Very nice!  Looking forward to your further impressions of the Nhoord drivers.  I am considering those and the Magnums.
