10 - 125 watts suggested amplifier range: JBL engineers designed the Loft40 bookshelf speakers to produce precise, exceptional sound from a receiver or amplifier capable of delivering up to 125 watts.
5-1/4" (133mm) PolyBass woofer: Paper produces the most natural sound of all driver materials. We've reinforced the Loft40'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 Loft40'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 Loft40'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 Loft40 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 Loft40 doesn't over-emphasize or under-emphasize any sounds. With a frequency response of 55Hz ? 20kHz, it reproduces a true, full sound range from deep bass tones to ultrahigh frequencies.
Connect wirelessly via dual-band Wi-Fi connectivity or Bluetooth 4.0, as well as wired via an asynchronous USB Connection, digital (TOSLINK) input, or an RCA analog input.
The LS50W uses a 5.25" Uni-Q driver capable of reaching down to 40Hz, combined with a built-in 192Khz/24bit DAC and 230W amplifier.
Wirelessly control the LS50W with the accompanying iOS or Android app. Wi-Fi Network Standard : IEEE 802.11a/b/g/n. Wi-Fi Network Frequency Band : Dual-band 2.4GHz/ 5 GHz
If you're after additional bass, the LS50W can output to a connected subwoofer. Output to the connected subwoofer is controlled by the LS50W app. Frequency Response : (plus/minus 3dB) Measured at 85dB/1m
Choose from Titanium Gray/Red, Gloss Black/Blue, or Gloss White/Copper for your LS50W.
The LS50 radiates an extremely large listening sweet spot and delivers a remarkably fast, clean, and expansive sound with its Uni-Q driver array.
The construction of the LS50's cabinets plays a big part in their sound. From baffle shaping and port design, the LS50 reproduces your audio completely flat and unaltered.
The LS50 comes in four spectacular colors, each with its own corresponding Uni-Q driver array color and frequency response is 79Hz - 28kHz (±3dB)
The LS50 is one of the most award-winning speaker products ever released by KEF, receiving accolades from such publications as Stereophile, What Hi-Fi, and The Absolute Sound. Design - Two-way bass reflex
Frequency range (-6dB)-47Hz - 45kHz. Crossover frequency-2.2kHz. Maximum output-106dB. Amplifier requirements: 25 - 100 W, Sensitivity (2.83V/1m): 85dB
