All experts agree that it’s easier to accept a bad subwoofer than a bad Tweeter.This tweeter does never have bad sound. It can be pressed to a very high sound volume and still keep smooth delicate sound. We recommend this tweeter in first case. It’s perfect for a 2 way system with low X-OVER POINT and very good for 3 way system. For best result we recommend to try 6db or 12db sloop but we don’t recommend  more than that

The XXT30W is mounted in a closed Wave guide aluminum chamber.
