For me E2 is the best sub I used comparing with AM6 and MLS5. In fact I got positive results from the first hour. And now I'm in the second month and I still getting amazing results, I am planning to use it for 6 months. The majority of my time of listening I listen to ultrasonic by earbuds, I recommend you to try to use them but be carful and calibrate the volume as recommended.
