New Joseph Audio Pulsar Graphene 2

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 talking about, I've posted many, and I'm not the biggest proponent of WAWB speakers, but given your post, I though you might find it an interesting idea.

WAWB is a true 2-way, not a 3-way with coaxial.


The idea is to use a relatively small (3"-4") wide band driver to cover the mid-hundreds all the way up through the top octave. Takes crossovers completely out of the vocal range. You should visit DIYaudio or another site for more information on current thinking of this type of design.

Another way to think of a WAWB is a close cousin of full-range, single driver speakers, similar to the Fostex or Markaudio type of drivers.

Let me know if you try any of them,

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 would be useful.

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?

I find the SEAS drivers interesting. I’m wary of presuming that drivers will have a particular "sound" in of themselves. And yet I find that one of my favourite speaker brands of old - Hales, which use the similar SEAS drivers to the JA speakers - seem to share a real DNA in their sound. I owned the Hales Transcendence 5 speakers at one point, and still own the Hales Transcendence 1 monitors (and a Hales center channel) using those same SEAS drivers and I’ll never forget first hearing the Hales transcendence speakers in a store. Metal drivers back then (mid to late 90’s) had a rep for sounding a bit hard and metallic (deservedly or not).But the Hales speakers sounded super smooth, rich, organic and with an eerie timbral believability that just grabbed me. I’d rarely heard a speaker that could produce such a believably wide array of timbral signatures. And a notable quality of the sound was a pristine smoothness and lack of etch or hash.

My only quibble that arose over time with the Hales is that they could be a bit dynamically reticent and that smoothness/clarity lack of hash could sometimes seem a bit too smooth. There was just a bit of glaze over the sound, so for instance there wasn’t quite the in-the-room texture of a bow on a violin or cello string.

The only other speakers I’ve heard that sound like the Hales are the JA speakers. They have that super smoothness combined with richness and clarity, and a signature "lack of grain/etch" sound. And if I have any quibble with the JAs, it’s that like the Hales they can sometimes have just a bit less texture than some other speakers. Though it’s not to as great degree as the Hales speakers.


But the Hales and JA speakers share such a special signature, and given their mid/woofer drivers are both SEAS and look so similar, it’s hard not to intuitively attribute something to the character of the SEAS drivers.A special blend of grain-free clarity and warmth.
