Review: Buone casse unico neo che i tweeter sono troppo squillanti per i miei gusti certe frequenze sono troppo alte ho dovuto abbassarle parecchio da EQ, bassi e medi sono abbastanza bilanciati
Review: So good I got another set for the front doors after one of my speakers blew. crisp and clear and plug and play with the adapters for for VW. Fit like a glove and perform brilliantly. Well worth the price in my view.

Good quality for the price point, improved the bass quality. Previous speakers I tried kept on sounding very "tinny", but these JBL's have brought the difference I wanted. Very happy with my purchase.
