About the JBL HDI-3800

A true tower of power

JBL has been developing brilliant speaker technology for decades, and they integrated that knowledge into this big, beautiful speaker. The JBL HDI-3800 features three 8" woofers and a horn-loaded compression driver that can stand up to all the sound the woofers produce. And it comes in three gorgeous finishes that match just about any decor.

A true tower of power

JBL has been developing brilliant speaker technology for decades, and they integrated that knowledge into this big, beautiful speaker. The JBL HDI-3800 features three 8" woofers and a horn-loaded compression driver that can stand up to all the sound the woofers produce. And it comes in three gorgeous finishes that match just about any decor.

Impressive compression driver

JBL uses horn-loaded compression drivers in speaker arrays for large concert venues — they fill space with clear sound in a way a standard dome tweeter can't. This same technology is used in the HDI-3800 floor-standers. That means you can enjoy for expansive, crystal-clear sound. The driver is recessed in a waveguide, which ensures that detailed high frequencies are dispersed across a wide seating area.

A solid foundation for midrange and bass

Each speaker's three 8" woofers are lightweight, rigid Advanced Aluminum Matrix cones. They feature a long-throw voice coil for high output and low distortion, serving up midrange detail and deep bass. The drivers are housed in an elegantly rounded cabinet made from 3/4"-thick MDF and heavily braced to eliminate sound-muddying vibrations. 

My first-hand experience with JBL HDI-3800 speakers

JBL demonstrated the HDI-3800 in our training room at Crutchfield HQ. I got a chance to listen to a pair powered by the Arcam SA20, which provides 150 watts at 4 ohms — plenty of power to fill the high-ceilinged room, which also contained around 20 Crutchfield employees.

I was just blown away by the room-spanning soundstage these speakers produced. A JBL rep used Jamestown Revival's cover of Helplessly Hoping by Crosby, Stills and Nash as a demo track, and the gorgeous vocal harmonies produced goosebumps. The singers' voices blended smoothly, but each voice was also distinct within the mix. You could hear every nuance, with an inviting sense of space around it.

The experience was similar with instrumental music. I could pick out individual instruments and locate them in space, which is exactly what I expect from a speaker in this class.

The percussion was powerful. With three 8" woofers in each speaker, you get an absolute wall of sound, including plenty of low end.

I'd be remiss if I didn't point out that they're flat-out beautiful to look at, too.

What about amplification?

The HDI-3800 speakers have a sensitivity rating of 92 dB. That's pretty efficient – especially for speakers in this class. But with a nominal impedance of 4 ohms, you'll definitely want an amp that's 4-ohm stable. We always recommend solid power to get the most out of any pair of speakers.

Got wire?

The HDI-3800 doesn't include any speaker wire. Read our article about choosing and installing speaker wire.
