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.
Product Features:
  • 10 – 100 watts suggested amplifier range
    JBL engineers designed the Loft30 bookshelf speakers to produce precise, exceptional sound from a receiver or amplifier capable of delivering up to 100 watts.
  • 4" (100mm) PolyBass woofer
    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.
  • 1" (25mm) soft dome tweeter with EOS waveguide
    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.
  • FreeFlow port technology
    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.
  • Straight-Line Signal Path (SSP) design
    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.
  • Accurate frequency response
    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.

Rated 5 out of 5 by from Excellent Little Bookshelf Speakers This is my first time I have owned a JBL brand product. I needed a small set of speakers that were well built & could handle high volume without distorting. I thought I would give them a try because they had a full crossover & they were priced low at $52.99 at the time. I took 12 hours breaking them in at moderate listening volume & they sound excellent. They can get loud without distorting & they produced better bass than I expected they would for there small size. Excellent sounding set of little bookshelf speakers & worth every penny.

Rated 5 out of 5 by from Great Compact Loudspeaker I just bought my second set of Loft 30 bookshelf speakers. I replaced a set of JBL FLIX 1 surround speakers with them. Don't get me wrong; the FLIX 1 speakers were awesome but at the price JBL was offering the LOFT 30's I couldn't resist getting another pair. These are a great pair of wall mountable bookshelf speakers that produce really big sound. They are very easy to mount on the wall and I especially liked the metal brackets on the back of the speaker that ensure the brackets will not come apart. These speakers are a handsome addition to the ES80 floor standing speakers, ES250 subwoofer, SB100 sound bar and SC305 center speakers that I have in my living room. This system just flat rocks. I highly recommend these speakers for anyone that wants high quality sound at a price that is lower than you would expect to pay for much lesser systems.

Rated 5 out of 5 by from A Little Gem I bought a couple of pairs of these for friends who had decided to add a little receiver and speakers to their t.v. I was surprised first by the solid construction. They have heavy cabinets for their size. Then the sound impressed me--quite full range for their size and well balanced, natural sounding. Their size makes them easy to place. A high quality speaker on all counts.

Rated 4 out of 5 by from great addition I bought these with the intent to replace "computer speakers" but ended up using them to replace my left/right side satellites for my 5.1 surround as they are just midrange and tweet. They are quite awesome in this application. not too big, and are wall mount ready. That said, I also got a great deal on them in the outlet.

Rated 5 out of 5 by from I'm using these for center the channel. I bought these 3 or 4 months ago. There was a terrific sale on line. I noticed the drivers were the same as the center channel sound bar, so I tried them out and have been very satisfied. Note, the binding posts were not the "standard" 3/4 inch spacing.

Rated 5 out of 5 by from Great Budget Speakers I bought this a while back as a compliment to their matching center channel Loft 20's. While not as full sounding as the Loft 40's, the 30's do a good job and pair well with a small sub.

Rated 5 out of 5 by from Very good little speaker when paired with a sub! I bought 5 pairs of these about 3 months ago and finally got around to putting 5 of them in my man cave/home gym. I sold high-end audio for about 7 years, and still do some large commercial systems and whole home systems. My reference speakers are KEF LS50's at $1500 pair. I sat the little Loft 30's next to the KEF's, and let them play for few days while I was at work. The Loft's actually compared much better than I thought they would! At 10x the retail price, and 25x what I actually paid for the KEF's and Loft's, the value is amazing! The KEF's had much better low frequency extension and a much broader, more open soundstage. They also had more midrange warmth than the JBL's. But with rock or techno music, the JBL's were very impressive. The high frequency extension seemed better, or at least louder, than the KEF's. But it wasn't offensive. In fact, I felt cymbal crashed actually sounded more correct, more live, on the Loft's (I have a set of Yamaha Stage Customs with Zildjians in my basement). The clarity of the upper midrange, and the overall intelligibility of the vocals--especially dialogue on video sources---I just slightly preferred on the JBL. Amazing. When paired with a subwoofer, and high passing both speakers. The differences were still there, but the overall difference in the sound experience was narrowed. If I was in a store and buying speakers, and you had these sitting side by side with the KEF's, and the salesman said these are $39 a pair (caught the Loft's on sale) and these are $1500 a pair, there may not be many people who would pay the extra money. Some would, the KEF's are still a Class A speaker in Stereophile. But for most people, in most situations, these little puppies are fine...maybe really fine. I have to award my star ratings keeping in mind the value---I've not heard anything even close at the sale price range.
