Our display JBL 4365 studio monitors are now fully on song after an extensive run in period. All of the slightly square edges to sound from the box fresh speakers have vanished and I am now delighted with the performance on offer; the JBL 4365 are testing competition against other speakers for sale at this price point without doubt. The glorious bass performance from the large drive unit is matched by the involving and detailed higher frequencies from the compression driver. Huge scale coupled with a complete sound through the frequency range keeps me reaching for more music. If listening to music is your passion the JBL 4365 deliver an involvement at low volumes like few other speakers i have heard. At high volumes the sound is addictive.
