Tips & Tricks:
When using Acry-Tech DuraTex, make sure your enclosure is sanded and painted properly, leaving no blemishes because they will show through.
After about 20+ listening hours, the sound quality is pleasing. Warm and inviting. The stage is large and if you’ve heard the NS3, you are aware of the detail these drivers produce. Much more low end than expected I’m guessing around 50 Hz. Battery life is about 8 hours at 50% volume listening to all genres of music. I imagine battery life would double listening to music with less demand from the driver.
