Are Sound Waves Able To Penetrate Canvas Painting?
Use your own ears. Seriously. Put the canvas up and put your ear against it. You'll hear what reflects and what does not pretty easily.

If Jeff says that graphene covers the cones, then I would take that to be the truth. I have found Jeff to be an honest and forthright guy, and I believe his representations without hesitation. Except as noted above, he's selling the Pulsar as u... 
Ugrade-itis - is there a cure?
At a certain point you realize you are playing rock-paper-scissors in the most expensive way possible. Finding a way to be happy without spending money is actually possible.Best,E

I wonder if it has any effect at all? I mean, Magico claims it is on the cover of their Be tweeters, and now Joseph will claim it covers the Magnesium cones... how would we honestly know?? Remember the fake Be driver scandals??  
A Ghost in the System? Music Thru Speakers with Preamp Disconnected
By disconnected, do you mean you removed the interconnect cables? If yes, then power issue. If not, you are getting crosstalk from the preamp, though it is usually thought of as a Left to Right thing, it's also possible to get it from one input pa...

Also, kind of interesting that Seas makes a lot of woofers for Magico, I wonder if this is a new OEM offering they are making?

That’s weird. Graphene is a damper? I would have assumed graphene was a stiffener. All cones ring somewhat, metal especially, so my point was if the graphene coating reduces the ringing mode, either by damping or elevating the ringing frequency it...

I see a thread by you about that about a speaker where the woofer covers 400hz and below. Isn’t something like the Kef Reference 1 or TAD ME-1 the closest to that concept in practice--basically a 3-way coaxial? I'm not sure what thread you are ... 
For those who've moved from "vintage" to newer units

DIY the speakers! Plenty of great DIY kits out there, fun to do with others.

I think driver integration can be done well at any point, but have you tried woofer-assisted wide band? May be your cup of tea. :) Best,E 
Identify a Resistor in an Audio Research PH3
Um, why not take them out and measure??  
Replace Squeezebox Touch and improvement in SQ
I did not know Roon supported SBTs! That's interesting indeed!  
Display off- any benefit?
I haven’t. Really kind of depends on what’s going on, and how well isolated those power supplies are from the audio. As I recall, this technology has come a long way. Lower power requirements, less scanning of LED ports so less digital noise to st...

Hey @wildfoxinn that’s a really good catch! You are quite right. Nothing in the FR plots, impedance or dispersion points to the claimed infinite slope. Looks like quite traditional 2nd order, with a possible impedance correction circuit thrown in ...
