YamaHeil's

[Vint Age]

Were picked up by fellow AKer 'brainsmasher' this very morning. Won't have for at least another couple of months (after my move in July). Actually, they are the NS-1000 and not the 'M' (monitor).

Yes - I know. I was looking at them too but with the shipping and brokerage fees and taxes into Canada ... :tears:

Hope the grill on the mid is not in too bad shape. :thmbsp:

 

[Vint Age]

well, I never heard the JA-0513's, but the Heils are excellent, they probably sound better than stock!

Better than stock? lol Acoustic suspension speakers with a bass reflex vengeance.

 

[bolly]

triple better than stock!

 

[Vint Age]

triple better than stock!

If you only knew.

 

[bolly]

ya never know vin tage, one day I'll hear a servicable pair of 1000's, untill then I'll settle for those breathing, living-being, almost animate objects known as IMF. :thmbsp:

Something tells me OEM tweets will sound better than whatever you decide to toss into the scenario, although it'd be interesting to hear those Heils.

If you're looking to try alternative tweeters in those Yamahas, I can't help but wonder if there isn't a good ribbon tweeter that you could drop in place of the original dome tweets? Might actually be an improvement on the design?

Chari, I believe Infinity EMITs were ribbon tweeters, no? I personally don't much care for their sound. I used to, but there is something unnatural about them.

The Heil tweeter is unlike any ribbon (not really what it is I guess) tweeter I've heard. Very natural sounding. Radiates sound from both front and back. Very life-like soundstage. I hear things in the music that make me turn my head to see what is behind me, and that is in the basement cavern.

Aaron, you'll have to stop up and have a listen, or I can lug the beasts down to your place for a listen. The big Kennys driving these effcient speakers may be fun.

love them Heil's!

probably true Aaron, about the OEM tweets. This was just a test to determine functionality... not sure this sound's for me anyways, not with Bryston's, too bright!

Chari, I believe Infinity EMITs were ribbon tweeters, no? I personally don't much care for their sound. I used to, but there is something unnatural about them.

Infinity EMITs are regular push-pull planar magnetic drivers. They consist of an etched voice coil on a Mylar backing placed between two layers of Samarium-Cobalt "Rare Earth" magnets. They could be viewed as borderline quasi-ribbon similar to Apogee drivers except the all edges are secured to the rest of the diaphragm vs. being suspended just on the short ends. A true ribbon tweeter is just a strip of very thing metal foil, typically 5.8micron Aluminum, connected at the short ends crimped in a saw-tooth pattern to allow for some flex in length and suspended inside an intense magnetic field (0.5 Tesla or higher) created by a strip of "rare earth" magnets on either side. A true ribbon tweeter like this is something special that no regular heavy dynamic driver (like the original Beryllium domes) can compete with and only an ionic/plasma tweeter can beat.

As to the EMIT tweeters, there were some excellent units and some just a bit below. Your former Infinities were one of the budget models with the budget EMITs. Beyond that, the main issue with EMITs sound unnatural or adding an "etch" to the music is not due to the drivers themselves but due to the crossover, ime. In my Infinity Quantum 2s with the bigger, better EMITs, I was able to cure this etch by replacing the cheap metalized polyethylene caps with Solens polyprops bypassed with 1mfd Wima MKP4 caps (same used in the TOTL B&Ws) that I surprisingly had floating around in my junk box. Also, the EMITs and similar planar drivers from Infinity, such as the EMIMs, EMIRMs, and L-EMIMs are very revealing of the upstream components and so will sound good or bad depending upon what's feeding them.


Whew, hang out on AK long enough and you get pretty good at shoveling it. :thmbsp:

They can be a bit on the bright side, but I would not call it aggressive. I'm thinking my AMT 4's hooked to a Sherwood S5500 or Pilot 245A may be a great combo.

Probably easier for me to haul the L-09's over, as they have convenient carry handles. I'd love to hear them sometime.

 

[HWF1]

The plant looks very happy. :yes:

 

[bolly]

:lmao: HWF1! :thmbsp:

 

[jtgofish]

Bolly,You are a third of the way to making a good speaker.Just replace the woofers with something that breathes a bit and the mids with something that images precisely and you could really have something.

 

[bolly]

don't have to jtgofish, got my IMF's!

But 'twas well-shoveled indeed. It has the earmarks of a future Sticky.

Obviously someone else whose never heard a pair of 1000's!

I have. Pretty nice speakers, but wouldn't be on my shortlist of must haves.

 

[Vint Age]

Greg - how do the mids sound? Any buzzzzzzzzing?

 

[bolly]

have to update my ad as they have found new homes, Heils not included.

no Nick, the crack is more of a split and I'm not sure it goes right through the dome... really less than 1/4" long. Got lucky I guess! :yes:
