The Gladen GA-38SG (NG) represents a special feature on the car audio speaker. It has an above-average diaphragm and is, therefore, able to play deeper into the midrange (up to 2000 Hz) than conventional 25 mm or 28 mm tweeters. Thus, for example, in problem vehicles where woofers are positioned unfavorably and thus have a reduced midrange reproduction, this can be compensated by the Gladen GA-38SG.

There is the tweeter in two versions. The GA-38SG-NG is a "non-glued" version. The tweeter capsule is not glued in the aluminum carrier as in the GA-38SG version. This allows high flexibility during installation and optimal integration into the vehicle.
