Whether you are building a stereo, five-channel, or seven-channel home theater system, the JBL Loft 40 bookshelf loudspeakers come in a small size with a modest price tag, without sacrificing performance. The 130mm (5-1/4") PolyPlas low-frequency driver delivers tight bass, and the soft-dome high-frequency transducer produces clear, natural sound for even the most complex musical passages. The tweeter integrates an Elliptical Oblate Spheroidal™ (EOS) waveguide, so sound quality is consistent over a wide listening area. The Straight-Line Signal Path™ crossover network built into all the Loft Series speakers creates seamless speaker-to-speaker sound movement for an immersive audio experience.
