Compact and elegant 4" bookshelf speakers for those with discerning taste.

To meet the needs of discerning audiophiles who place as much importance on style as they do on sound, we’ve created the Loft Series. Designed for home audio use, this line of speakers delivers the great JBL® sound that you’ve come to love in a contemporary form factor that is sure to make a statement. The series’ Loft30 is a pair of compact, two-way speakers made for the bookshelf or the wall. (Either way, you’ll want to show off their elegant looks.) Each speaker in this pair features a 4-inch (100-millimeter) PolyBass woofer for clear, resounding bass and a 1-inch (25-millimeter) soft dome tweeter that can reach frequencies up to 20kHz. Each tweeter also features our proprietary Elliptical Oblate Spheroidal™ (EOS) waveguide, which evenly distributes sound throughout your home theater and makes every seat a perfect listening position. The Loft30 speakers also use our Straight-Line Signal Path™ (SSP) design to ensure that a strong, precise signal arrives at each driver with little alteration from the original source. Whether you crave a two-channel stereo setup or a multi-channel surround-sound system, the Loft30 bookshelf speakers are ready to blow you away and look good while doing so.

JBL engineers designed the Loft30 bookshelf speakers to produce precise, exceptional sound from a receiver or amplifier capable of delivering up to 100 watts.
Paper produces the most natural sound of all driver materials. We’ve reinforced the Loft30’s paper woofer cones with a proprietary polymer that provides additional stiffness and damping to the cone surface. These qualities provide the listener with tight bass and extended low frequencies without breakup or distortion.
The Loft30’s tweeter features a 1-inch (25-millimeter) soft dome with high sensitivity and fast transient response for accurate high-frequency reproduction. The tweeter integrates with an EOS (Elliptical Oblate Spheroidal) waveguide, giving high-frequency sounds a wide, consistent listening window. The result is an incredibly broad stereo image across a huge listening area.
A rear-firing FreeFlow™ port is acoustically matched to the Loft30’s woofer to move air out of the speaker’s cabinet. You’ll get extended bass response with low distortion, adding power to your music and excitement to your movie soundtracks.
The ideal path from input to components to transducers is a straight line. The Loft30 takes that path. Its Straight-Line Signal Path (SSP) technology preserves the clarity, detail and dynamics of your favorite audio content.
The Loft30 doesn’t over-emphasize or under-emphasize any sounds. With a frequency response of 70Hz ? 20kHz, it reproduces a true, full sound range from deep bass tones to ultrahigh frequencies.
