What you know another Tesla magnet driver. In fact I believe it was Beyer who did it first.
NA1 uses similar tech for their driver using dual voice coils. Ya these go for $899 here according to amazon current RP. Similar hyper clarity. Very extended treble with a deep reaching low end rumble. To be fair it has been a while since I heard these but the NA1s exhibit very similar sound Characteristics.
This is from the sales page describing the tech behind the NA1
Balanced voice coil
The split vibration of the dynamic driver causes distortion, and the unilateral lead of the conventional dynamic driver is an important cause of the imbalance of the diaphragm weight. The MCL2-10 dynamic driver uses bilateral voice coil leads, and the diaphragm quality is more balanced, which effectively reduces distortion and makes the sound more pure.
Tesla double magnetic circuit
Magnetic force is the source of power of the dynamic. The MCL2-10 driver adopts dual magnetic circuit design. Two high-performance rare earth NdFeB magnets provide magnetic flux of more than 1 Tesla, which provides greater driving force, higher sensitivity, better dynamics and transient performance.
Double cavity design
The traditional dynamic driver has only one rear cavity. The MCL2-10 adds an additional rear cavity to the base, which can control the air pressure more precisely, make the diaphragm movement smoother, the sound field is more ambitious, and the sound details are more abundant.
Well-designed 3D driver protective cover
The sound from the diaphragm will be transmitted to the cover for the first time, and the design of the hole of the cover is extremely important. The MCL2-10 adopts a specially designed 3D cover that effectively reduces reflection interference, making the sound more full and the low frequency more abundant.
5-axis CNC aviation aluminum panel + pure copper damping balance system, let each song want a single cycle
The dynamic earphones tuned, the cavity reflection and the air pressure balance of the front and rear cavity are the most important. The back cover is carefully carved by the aviation aluminum through the 5-axis CNC to effectively improve the high-frequency response. At the same time, in order to pursue a more precise air pressure balance effect, NA1 uses two air flow control components made of pure copper to better adjust the air pressure balance of the front and rear cavity, so that the low frequency is full of elasticity, and the medium frequency and high frequency are rich in texture. Let you feel the lines between the vocals and the instruments, so that each song is remote, wide, natural.
Got a lot going on for the NA1. I bet xelentos have better tonality and is more technical but the NA1s will not be too far behind in these aspects.
