i think it have the driver size of 53mm, and possibly the OFC6N voice coil.
Which i think same as W1000x possibly
The ESW11LTD probably has a different driver even if it's the same size as ES10.
ESW11LTD lists 44 Ohm impedance while ES10 lists 42 Ohm.
And if my experience with ES10 with lambskin ear pads is any indication, then the soundstage of ESW11LTD will be enormous for a portable.
What makes you think that the guys at AT are lazy? I wonder why these topics always come up again when new AT headphones appear.. back then people spread rumors that the A900LTD shared the same driver as the L3000 which is just absurd having owned both. W3000ANV has 40 Ohm impedance and the 11LTD 44 Ohm so they are obviously different. Isnt it obvious that drivers need to be tuned to the circumstances of their application? Most companies with bigger product lines have similar/same looking drivers, for example Grado or Ultrasone.
PriceJapan says these are due out around mid-November (the 15th is the target date AFAIK). You can reserve one if you pay in full.
Came out to be over $700 USD with shipping. Yikes. I put in my order however.
That's about what the ESW10JPN was when it first came out, too. It dropped in price afterward however.
From the Singapore HardwareZone forums, a user who demoe'd these and compares these to ATH-ES(W)10 writes "Both exhibits similar sound, with ESW11's bass extend further down compare to ESW10. The bass has more oomph but is controlled, unlike the ES10 which I find to be overwhelming."
As a lover of sub-bass, I hope this is generally accurate. The $700+ pre-order price to too much to swallow though. I can almost get a pair of LCD 2's for that much. $523 is more reasonable. I hope they can be had in the U.S. for under $500!
