Four custom spec'd high-impedance drivers coming in soon. N52 magnets across the board - bio, graphene, wool, Be-coated. Cant wait. Dec 2, 2020 at 9:10 AM

        You should pop em into a Grado-esque enclosure with extended front baffles for more conventional pad fit! Bruce at Wabi Sabi could probably do this for you (fleasbaby on Etsy). He makes my XL cups, he's very interested in atypical and experimental designs. If you ever want to take your builds to the next level!

        Also if you want better sub extension you should vent your baffles, I did notice some flex on the cardboardophone despite the perf pads.

        Very curious about the graphene driver. Also nice to see graphene falling in cost vs ~10 years ago and becoming much more readily available and widespread.

        Unless I can get a perfect-condition Nak 3-head under $500 or Theta Gen V under $700, I am done buying audio shit. If anything, hoping to downsize and optimize.

        A very worthy exception. Built like a tank, will last forever, VPI supported, many available tweaks (but will sound great as is). A total steal.

        It is massive, though...

        I once auditioned a 700. The owner played it while I was checking his CD transports. It completely destroyed the cd players. Extremely refined, immediate and deep. I wanted it right then, but someone else had already paid for it

        As an ex-sax player I have no idea how he could get such a subdued and mid-forward, almost woody resonance. Partly the recording, but still, that's just his sound. I always played so bright and zingy. I admire his breath control throughout his dynamic range.

        I actually forgot how strong the magnets on the 900s were— friggin hell that explains a fair bit (have the 1.5T claims been ratified? That's obscene strength).

        Yeah at this point your best bet is likely to find some enterprising guy willing to manufacture parts to your spec. Idk honestly there's likely a dude somewhere who's already got it down pat.

        @tommytakis pointed me in the right direction and already in the works to produce a nanofiber driver (either paper or compressed wool, though options like graphene exist) with an N52 magnet that's even larger in physical size than the one on the 900. Same venting scheme. Next up is making baffles.

      Full Compass is no longer selling TH900 drivers to customers, only 'authorized repair shops'. I guess ESX900 is now dead, unless OEM option?

        TH900 drivers feature the largest magnet of any dynamic driver in existence. I am working on a customized oem option now.

        I mean if you get a stock TH900 I'll still do it, might charge less for labor too given no transplant needed. Just more cost up-front for the donor phone.

        Still blows my mind how much the TH900 driver scales despite the low impedance. Every minor system change is a night and day difference.

        The room can be a cruel thing. Also Naim + Focal stuff is too bright and etched. Polaris is bass boosted with polite treble if I’m not mistaken - not exactly aligned with lean/dynamic/bright Focal/Naim. He needs to switch it up.

      'The Augmented Heart' by ohbliv is difficult for a system to land, but truly satisfying if it all comes together. Unique noir aesthetic too.

        Meze Empyrean tried putting different traces on the same driver for different frequencies. The result sounds like mush with poor coherency. I suspect dual SE drivers in a planar headphone would also tend towards a mushy sound that lacks the coherency I like.

      2. E_Schaaf
        E_Schaaf
        The TH900s push some serious air, I'm going to seal off the baffle which is normally vented so these passive radiators get smacked with quite a bit of energy on the backwave. On a fully sealed cup with the sealed baffle you can feel some pretty intense vibrations in the cups from the outside with your fingertips even with pretty heavy damping inside. I think it'll push the 2" passive just fine.

      3. E_Schaaf

        That's with the majority of the rear driver vents opened. With the normal stock paper covering there's much less backwave energy, but all those nasty treble peaks...

        Makes sense, I was just thinking in my mind of a more discrete design, like how some headphones are discreetly ported. But yeah, I guess a 2" passive radiator does make sense with a 50mm driver, as 50mm=2" anyway. I was thinking 2" was much bigger than 50mm with my quick mental conversions, but thats wrong.
