JBL Loft 50 Three-Way Floorstanding Loudspeaker (Pair)

Elegant tower speakers with three 4" (100mm) midrange drivers and dual 6-1/2" (165mm) woofers. For those with a discerning eye for contemporary style and an ear for detailed sound, the JBL® Loft Series is the perfect speaker set.

The series' Loft50 is a pair of tower speakers that we've designed to reproduce your audio with incredible highs and lows. Their dual 6-1/2-inch (165-millimeter), side-firing PolyBass woofers allow each speaker to produce thunderous, floor-rattling bass; the midrange frequencies, where departures from faithful reproduction are most noticeable, come from three 4-inch (100-millimeter) PolyBass drivers; the highs come through crisp and clear at frequencies up to 30kHz with a 1-inch (25-millimeter) soft-dome tweeter that we've placed at ear level. We've equipped the tweeter with our proprietary Elliptical Oblate Spheroidal™ (EOS) waveguide technology, which creates a wide, consistent listening window, making every seat the best in the house.

Finally, the Loft50 speakers use a Straight-Line Signal Path (SSP) design to help ensure that a strong, precise signal arrives at each driver with little alteration from the original source. Not only do the speakers sound stunningly good, but their unique design meets the needs of anyone looking for space-saving audio components. These speakers are unlike any you may have experienced.

Features

For those who possess a contemporary taste in décor and an affinity for performance speakers, the JBL Loft series is the perfect hybrid solution. Smashing the myth that good sound can only come from bulky cabinets, the slim yet powerful speakers are technological marvels that develop full, rich sound from their ultra lean cabinets.

  • The tweeter features a 1" soft dome with high sensitivity and fast transient response for accurate high-frequency reproduction
  • The tweeter integrates with an Elliptical Oblate Spheroidal waveguide, giving it smooth integration with the midrange and a wide, consistent listening window to create an incredibly wide stereo image across a huge listening area
  • Polybass drivers feature paper cones that are reinforced with a proprietary copolymer to provide additional stiffness and damping to the cone surface; you get tighter bass and extended low frequencies without breakup and distortion
  • A Freeflow Port Architecture extends low frequency response by coupling internal air motion to a computer-designed aperture with a flared shape, allowing maximum air flow without audible port noise; the result is room filling bass from an attractive, slim speaker
  • The Straight Line Signal Path is a crossover design that provides the shortest route from the input terminals to the transducers, thus minimizing signal loss and noise; it helps to ensure that a strong, precise, and unaltered signal arrives at each driver

At a Glance:

  • 10 - 250 Watts Suggested Amplifier Range
  • Dual 6-1/2" (165mm) and Triple 4" (100mm) PolyBass Drivers
  • 1-inch (25mm) Soft Dome Tweeter with EOS Waveguide
  • FreeFlow Port Technology
  • Straight-Line Signal Path (SSP) design
  • Accurate Frequency Response


10 - 250 Watts Suggested Amplifier Range
JBL engineers designed the Loft50 tower speakers to produce precise, exceptional sound from a receiver or amplifier capable of delivering up to 250 watts.

Dual 6-1/2" (165mm) and Triple 4" (100mm) PolyBass Drivers
Paper produces the most natural sound of all driver materials. We've reinforced the Loft50'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-inch (25mm) Soft Dome Tweeter with EOS Waveguide
The Loft50'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 Loft50'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 Loft50 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 Loft50 doesn't over-emphasize or under-emphasize any sounds. With a frequency response of 37Hz - 20kHz, it reproduces a true, full sound range from deep bass tones to ultrahigh frequencies.

3 out of 5 eggsJBL Loft 50

Pros: Good looking, sound good for the price, good craftsmanship,

Cons: Sound do not exceed expectations, self adhesive rubber feet fall off every time I move speakers, not all of them, just one or two. Bought some with wood screws, guess what JBL, it works.

5 out of 5 eggsGreat for the price

Pros: I only paid one ninety nine for these on special. I have them hooked to a Harmon 70w per channel receiver. Great midrange and mid bass. Great for bass guitar notes. They drone good but do not hit or thump, of course you wouldn't expect that from 6.5's anyways.
I have a 8" sub that takes care of all the lows these can't hit.

Cons: Narrower than I expected, about 5", but they are deep. Not really a con.

Other Thoughts: I got these on sale and used a promo code and got them under two hundred bucks.

4 out of 5 eggsJBL LOFT 50 SPEAKERS (pair)

Pros: the speakers appear to be good quality and are very narrow in width (barely wider than the 4 inch front drivers).the sound is good in my smallish master bedroom.

Cons: the packaging is terrible. both speakers are in one large box with foam padding at the top and bottom with a narrow spacer around the middle. the box arrived with 3 large holes all the way through to the speakers and numerous dents. the bottom was crushed looking, like it had been dropped off a number of trucks. except for the top and bottom, there is only the cardboard box and a 2 inch air space between the speakers and the impacts. i was suprised that the speakers themselves weren't damaged.

Other Thoughts: speaker placement is critical with these speakers largely dut to the side mounted woofers, one on each side at different heights. i moved them around while listening to different types of music until they sounded right. you can't put them too close to anything to the sides, or the bass goes away.

5 out of 5 eggsNice for the Price

Pros: These are good sounding speakers, probably not premium but definitely good. Appearance is sharp, slim, and understated.

Cons: None

Other Thoughts: There are actually two offset bass speakers per unit. I couldn't tell that from the pics, but there is one facing each side. They are slimmer than I expected also. I'm waiting on the LOFT20 center channel to show up (purchased elsewhere) and some LOFT40s to complete a surround setup. A separate sub is still necessary. They also get loud and handle quite well.

5 out of 5 eggsCompletely Satisfied

Pros: Very satisfied with the sound quality, fairly loud in my current configuration which is by no means top of the line, and aesthetically pleasing.

Cons: Was a mild hindrance to have to attach the base plates to the actual speaker body, but anyone with a screw driver and 2 minutes can easily handle that.

Other Thoughts: Very happy with the purchase, would recommend to anyone looking for a decent floor standing speaker set.
