JBL LOFT 30 User manual

We apply the same legendary engineering that makes the JBL®brand a favorite of the professional music industry to
the JBL Loft Series home theater speakers. The most compact and affordable of the speakers in this series are the
JBL Loft 30 bookshelf loudspeakers. Each speaker has a 100-millimeter (4-inch) PolyPlas™low-frequency driver that
delivers tight, extended bass, plus a soft-dome high-frequency transducer that produces natural sound with superior
clarity. The tweeter also integrates an Elliptical Oblate Spheroidal™(EOS) waveguide so that sound quality is consistent
over a wide listening area. The JBL Loft 30 speakers are voice-matched with all the other speakers in the Loft Series,
making it easy to construct the sound system that fits your space and budget. Also, the Straight-Line Signal Path™
crossover network built into all the Loft Series speakers creates smooth, even speaker-to-speaker sound movement.
