JBL SB 300 review: JBL SB 300

JBL SB 300

The Good

The large size of the <b>JBL SB 300</b> makes it one of the best-performing sound bars we've heard. Its limited connectivity should be sufficient if you use your TV to switch between components. It also includes a remote, unlike some of its competitors.

The Bad

The SB 300's unique style won't suit every living room. There also isn't a front-panel display, a feature that's often included on sound bars half the price of the SB 300. And the bare-bones feature set lacks extras like AirPlay and Bluetooth that would be nice at this price level.

The Bottom Line

The JBL SB 300 is a plus-size sound bar with excellent sound quality, but its unconventional style won't please everyone.

The JBL SB 300 doesn't look quite like any other sound bar we've reviewed. Sure, the basic set of components is the same (wireless subwoofer, long cylindrical sound bar), but JBL has given the SB 300 an idiosyncratic style, with a twisting look to the speaker grilles and plastic cabinet of the sound bar, plus a subwoofer that looks more like Darth Vader's helmet than a piece of home audio equipment. You can't knock JBL for churning out a run-of-the-mill design, although different isn't always better.

The distinctive design is our main hang-up with the SB 300 (street price: $500), which delivers exceptional sound quality for a sound bar (second only to the Harman Kardon SB 16) and a basic, but sufficient, set of features. The best light to view the JBL SB 300 in is that you get almost all the performance of the excellent Harman Kardon SB 16 for $100 less. That's a relatively good deal if you're looking for a high-performance sound bar; just make sure you're willing to put up with the SB 300's in-your-face looks.

Design: Not another face in the crowd
Choosing a sound bar over a traditional home theater system would seem to indicate a desire for a home audio system that doesn't call attention to itself, which is what makes the look of the JBL SB 300 a bit puzzling. The sound bar itself is full of sharp angles and a glossy black finish, while the jumbo subwoofer will not only crowd small rooms, but its funky look won't be for everyone. The aggressive styling on both components isn't really our taste, but it's a matter of personal preference.

JBL SB 300's subwoofer
The SB 300's subwoofer definitely wants to be noticed.

Looks aside, the busy front panel of the sound bar doesn't have a display. That's unfortunate, as it's nice to get some visual feedback as to how loud the volume is or what input you're on. It's definitely not a critical feature, but most recent sound bars include a display these days.

JBL SB 300's front panel
There's no display on the sound bar, so you'll never be quite sure if you're close to maximum volume or not.

The JBL SB 300 thankfully includes a remote, although it's of the thin, credit-card variety. Quite a few sound bars don't include a remote (which can lead to frustrating issues), so we appreciated the thin clicker, even though we'd recommend picking up a quality universal remote to control your system with.

JBL SB 300's connectivity
The SB 300's jack pack is limited.

Connectivity is around back, and it's as simple as it gets. There's just a single analog audio input and there's an optical digital audio input--that's it. Even a basic home theater will likely have more than two devices, so JBL is counting on you to connect your gear directly to your TV, then connect the output of the TV to the sound bar. As long as your TV has the proper output, the arrangement should work pretty well.

Setup: Fully tweakable subwoofer
The SB 300 can be wall-mounted with the included brackets or placed in front of your TV. Once you've decided where you're going to put it, move the speaker's EQ switch to Wall or Table to optimize the equalization for your chosen placement scenario.

The SB 300 system's initial wireless subwoofer pairing is achieved by pressing the "pairing" buttons on both the sub and sound bar. The sub has two control knobs on its rear panel (volume and "subwoofer cutoff control"), both of which permit finer tuning of the system's bass balance than you can do on most sound bar/subwoofer systems.

Back of SB 300's subwoofer
The SB 300's sub is more tweakable than most.

JBL doesn't offer any specific guidance for setting the subwoofer cutoff control, which is traditionally known as a subwoofer crossover control. The range of crossover frequencies is continuously adjustable from 45 to 200 Hertz, and we used 200Hz for all of our listening tests. There's one other control, a "phase" switch with two positions, 0 and 180 degrees, and in most cases the 0 position will produce the smoothest blend between the speaker and sub. While all the adjustability is nice, note that changes can only be made on the subwoofer, so you can't control the subwoofer level from the remote.

JBL SB 300's remote
Since all the subwoofer controls are on the back of the sub, you can't adjust the subwoofer level from the remote.

All of that probably sounds more complicated than it is: pair the sub and bar, turn the cutoff control to its max position, put the phase switch to 0 degrees, adjust the subwoofer's volume to taste, and you're good to go. (It would have been nice if the manual said as much.) We recommend placing the sub within 4 or 5 feet of the sound bar to get the best possible sound.

Performance: Bigger sound bar, bigger sound
It didn't take too long to hear what separates the SB 300 from all of the smaller and less expensive subwoofer-sound bar systems: the JBL is considerably more refined and powerful-sounding. Sure, that big sub is responsible for the gravitas advantage, but the sound bar also exhibited above-average resolution of fine detail. The SB 300 delivered more of the visceral excitement in the "Inception" Blu-ray than any subwoofer-sound bar system we've tested since the Harman Kardon SB 16. (Harman and JBL are both subsidiaries of Harman International). It's not just a coincidence that both systems feature large subs and sophisticated sound bars.

The "Quincy Jones: The 75th Birthday Celebration - Live at Montreux" DVD sounded awfully nice. The stereo soundstage spread wide across the front wall of the CNET listening room, but this is strictly a two-channel system. Herbie Hancock was playing a funky keyboard slung over his shoulder as the band laid down heavyweight grooves. We noted that the blend between sub and sound bar wasn't perfect, so some bass notes were lighter than others. The drummer's cymbals had more sparkle and detail than your average sound bar would allow. This level of deep bass prowess and top-end resolution elevate the SB 300 to the top rank of integrated two-channel systems.

We still had the Harman Kardon SB 16 on hand, so we compared it with the SB 300 while watching the "Black Hawk Down" Blu-ray. The wide dynamics swings and power required to convey the fiery helicopter crash and battlefield explosions were impressively played by both systems. As we listened more, we felt the clarity of the gunfire exchanges on the city's streets was a wee bit better with the SB 16, and the low rumble of the large military vehicles had more low-end weight on the SB 16 too. But the differences between the two systems weren't major, and both sound a lot more powerful than any other subwoofer-sound bar systems we know.

Switching to stereo music, Radiohead's "OK Computer" CD sounded a little bright on the SB 300. Thom Yorke's vocals and the guitars were too thin, but there's no way to adjust the sound bar's tonal balance. At this price, JBL should have included bass and treble controls, or at least a few preset EQ options (rock, jazz, acoustic, and so on). On the other hand, bass definition and power on The Dead Weather's "Sea of Cowards" CD were excellent. In short, the SB 300 can play louder than most sound bars, but it's still better suited to movies than music.

Conclusion: A good deal, if you can tolerate the look
If your main concerns are sound quality and value, the JBL SB 300 is a great pick, delivering most of the performance of the Harman Kardon SB 16 for less money. Just make sure the SB 300's style is right for your living room, as it tends to stick out more than blend in.
