Loft 20


150-watt, dual 4" two-way center-channel speaker

Product Actions
Compact and elegant 4" (100mm) bookshelf speakers designed for those with discerning taste.

Today’s flat-panel televisions provide you with a clear, high-definition image, and they look stunning. Their thin profiles enhance your listening space without taking up too much of it. To complement these slim TVs, we’ve created the Loft Series of home theater speakers. Their look is contemporary, and their sound is out of this world. The series’ Loft20 two-way center-channel speaker handles vocal reproduction with clarity, precision and presence. Dual 4-inch (100-millimeter) PolyBass woofers bring you resounding lows and clear mids that will make you feel as if you’re sitting in the middle of a movie or concert. A 1-inch (25-millimeter) soft dome tweeter delivers high frequencies up to 150kHz – far beyond the range of human hearing. The tweeter also features our proprietary Elliptical Oblate Spheroidal™ (EOS) waveguide technology, which creates a full, rich, 3D-like soundstage throughout your listening space. The Loft20’s drivers are also magnetically shielded, so you can place the speaker directly above or below your screen without worrying about its causing unwanted interference . We’ve voice-matched and engineered the Loft20 to complement other speakers in the Loft Series. From its elegant look to its breathtaking sound, you’re going to love how it fits into your home theater.

Rated 5 out of 5 by from The last piece to my updated surround system I've been replacing my 15 year old JBL 6.1 system, now a 7.2 with 6 Control One's and 2 Arena Sub 100P subwoofers. What a profound difference that his center channel speaker adds. The crispness and clarity of the sound and vocals that emanate from this speaker is awesome! While I loved the 6.1 system that I had, the difference and improvement with this speaker and the rest of my system is second-to-none. I consider myself and audiophile and have been a JBL'er since 1982. I have never been let down. I also have to floor tower speakers that I have had for 16 years. They haven't begun to fade.

Can the Loft 20 be mounted to the wall? Does JBL have any in-wall center speakers?

Asked by: Griz Green
Mounted to the wall using 2 L brackets. Has worked for years. I guess that's kinda like a shelf but semi invisible.
