Choosing Between the Revel M16 and JBL Stage2 250B: A Deep Dive Into Modern Bookshelf Speakers

If you're in the market for high-quality bookshelf speakers, the Revel Concerta2 M16 ($296) and JBL Stage2 250B ($320) represent two interesting approaches to the classic two-way design. Let's explore what makes each unique and who they might suit best.

Understanding Bookshelf Speakers in 2024

Bookshelf speakers remain incredibly popular for both music and home theater, offering an excellent balance of performance and space efficiency. These compact units typically combine a tweeter (for high frequencies) with a larger driver (for mid and low frequencies) in a carefully tuned cabinet. While they won't shake your foundations like tower speakers, modern bookshelf designs can deliver remarkable sound quality when properly positioned and powered.

The Technology Behind Each Speaker

The Revel M16, released in 2020, brings some serious engineering to the table. Its distinctive acoustic lens waveguide (which shapes how sound waves leave the tweeter) represents years of research at Harman's advanced research facilities. This technology helps create more consistent sound throughout your room, rather than just in one sweet spot.

The newer JBL 250B takes a different approach with its HDI (High-Definition Imaging) waveguide, designed to provide wider sound dispersion. This means you don't need to be as particular about speaker placement or listening position to get good results.

Driver Configurations That Matter

Both speakers use aluminum dome tweeters, but their implementation differs significantly:

• Revel M16: The 1-inch tweeter pairs with a larger 6.5-inch aluminum cone woofer, allowing it to reach lower frequencies naturally
• JBL 250B: Combines a 1-inch tweeter with a 5.25-inch polycellulose woofer, trading some bass extension for improved dynamics

Real-World Performance

Detail and Clarity

The Revel M16 excels in revealing fine details in music. When listening to well-recorded acoustic music, you can hear subtle details like fingers sliding on guitar strings or the natural decay of piano notes. The speaker maintains this clarity even at lower volumes, making it excellent for late-night listening.

The JBL 250B presents a more forward, energetic sound. While it may not match the M16's ultimate resolution, it delivers an engaging experience that many listeners find more immediately satisfying, especially with modern music genres.

Bass Response and Integration

Despite being bookshelf speakers, both handle low frequencies admirably:

• Revel M16 reaches down to 45Hz (-10dB), with notably precise bass control
• JBL 250B extends to 50Hz (-6dB), with a slightly more prominent mid-bass that can make music sound more full-bodied

For home theater use, both speakers benefit from crossing over to a subwoofer around 80Hz, but the Revel's more linear response makes this integration somewhat easier to achieve seamlessly.

Imaging and Soundstage

Here's where these speakers show their different design philosophies:

The Revel M16's acoustic lens creates a precise, well-defined soundstage. Instruments and voices are locked in space with remarkable stability. However, this precision comes with a smaller sweet spot – you'll want to position both yourself and the speakers carefully for best results.

The JBL 250B's HDI waveguide trades some of that pinpoint imaging for a more forgiving presentation. The sound field is wider and more consistent as you move around the room, making it potentially better for casual listening or when multiple people are watching movies.

Room Integration and Setup

Placement Considerations

The Revel M16 performs best with careful placement:

• At least 2 feet from walls
• Precise toe-in angle (pointing toward listening position)
• Benefits from high-quality speaker stands

The JBL 250B is more flexible:

• Works well closer to walls
• Less critical toe-in requirements
• Still benefits from good stands but less sensitive to placement

Amplification Needs

Both speakers present a 6-ohm impedance and similar sensitivity (86dB), meaning they'll work well with most modern receivers and amplifiers. However, they scale differently with better amplification:

• Revel M16: Really shows its potential with high-quality amplification (50-120W recommended)
• JBL 250B: More forgiving of modest electronics (20-150W recommended)

Value Proposition

At similar price points, these speakers offer different kinds of value:

The Revel M16 represents the audiophile approach, delivering reference-level accuracy and detail that punches above its price point. It's particularly impressive considering it inherits technology from Revel's much more expensive Performa3 line.

The JBL 250B offers a more practical value proposition, combining good sound quality with placement flexibility and robust construction. Its more forgiving nature makes it an excellent choice for real-world listening environments.

How to Decide

Choose the Revel M16 if:

• You primarily listen to acoustic, classical, or jazz music
• Your room allows for optimal speaker placement
• You have quality amplification
• Absolute accuracy is your priority

Choose the JBL 250B if:

• You listen to a wide variety of music, including rock and electronic
• Room placement options are limited
• You want speakers that work well for both music and movies
• You prefer a more dynamic, engaging sound

Both speakers represent excellent value in their price range, but they serve different listeners. The Revel M16 is the choice for the dedicated music listener seeking maximum accuracy, while the JBL 250B offers a more versatile, user-friendly approach that still delivers engaging sound quality.

Remember that speaker preference is inherently personal – if possible, listening to both models in your space with your favorite music is the best way to make a final decision.
