Default What Material is the Diaphragm of Yamaha HS5/7/8 Made From?

Hi


I wonder if it's possible to buy drivers that sound like the Woofers in the Yamaha HS5/7/8 Monitors..
(without spending 400-600$)

Click the image to open in full size.

HS Series - Overview - Yamaha - United States


Does anyone know what material it is made from?

And what driver would give a sound that is close to it?


Thank you

Being actively powered monitors, the material from which the drivers are fabricated is only one factor in the complex formula arriving at the “sound”of the system.
That said, as the marketing ad copy starts with a reference to the “iconic 70’s nearfield reference monitors”, and all the photos seem to show fairly simply cone profiles, my first intuition would be paper.

Thank you Chris.

If someone goes the DIY route,
is there a 6.5" driver that can be purchased and gives as good sound as the HS7 does?

These monitors are trying to go for the look of the legendary NS10’s which used a white paper cone that was actually rolled up and glued with a seam (straight cone profile). The reviews of this speaker with measurements don’t look particularly good. I think you can do a lot better with many drivers from Dayton or ScanSpeak or SB acoustics. They won’t be white though. I think they may actually be made of white polypropylene rather than paper. Polycone woofers can be very smooth.

A few suggestions - low cost would be Dayton PA120-8 at $18, moderate price and very smooth would be Aurum Cantus AC130 MkII $70, and higher price and excellent would be SB Acoustics Satori MW16-8 $148, or ScanSpeak Revelator 15W/8531 at $211. All here are paper except the AC.

I would:
1. Get some decently made but not too expensive paper cone drivers.
2. Paint them carefully with the desired colour.

Well I'm flexible regarding the material, if the result can be as good.

You say that you believe this will achieve a result which is a lot better than the HS7?

That's amazing.

Thank you so much for the recommendations.

I could find all the drivers you wrote in google, except the Dayton PA120-8.
Maybe their name is slightly different?

Sorry typo. PA130-8

One more came to mind - this one is treated paper so appears to be shiny plastic but sound is very very good. It’s the one in this kit: XLS- Encore. The MW130 for $27.
M130 Woofer

The kit is $250 (pair) and includes all drivers, tweeters and crossover. You just need to make the box. It’s an exceptional speaker. You can’t touch it with a DIY effort for the same price.

X-LS Encore kit

I have this kit and can attest it’s superb.

I have recordings of the PA130-8 and AC130 in several threads. The PA130 has recordings in the Daytonator thread.
The Daytonator - PA130-8X

The AC130 has recordings in this thread:
FR58EX and AC130F1 micro-FAST
