"...The transducers (drivers) are completely re-engineered and based on a neodymium ring magnet with optimized magnetic field characteristics. This combination creates a magnetic field inside the transducer which is far stronger (> 1,2 Tesla - measuring unit for magnetic flux density - with current headphones the strength of the magnetic field is < 0,65 Tesla) than in standard headphones. Because of this increased magnetic field, the voice coil is more compact but still provides a very high degree of efficiency. The membrane, consisting of a 3 layer „compound foil“, delivers an extremely precise frequency response and guarantees, in collaboration with the strong magnet, a transparent and distortion free sound."
The T 1 system something different again...it's no "New DT 48" or something like that.
By the way, I've just updated the DT 48 E product site:

Concerning the Marketing of the DT 48; we will not start a marketing campaign, internet banners, posters or whatever. It's mainly a combination of exhibitions and maybe even magazine tests and believe me, there have always been proper presentations of new products. The DT 48 is a very old model, which means also it's presentation has been many, many years ago 
Thank you all for your great support for beyerdynamic!
Many warm regards,
