The main reason the sE X1 is so good is that its large diaphragm, gold-sputtered capsule is handcrafted and handtuned by skilled technicians in our own factory. Surrounding all the important electronics is a sturdy metal chassis finished in acoustically damping black paint, to minimise any resonant frequencies in the microphone. The sE X1 is also equipped with a 10dB pad and a low-cut bass filter - essential features for using it in a variety of recording situations.
