JBL Multibeam vs DTS Virtual:X: Virtual Surround Compared

Two paths to a surround illusion

Virtual surround sound is a method of creating a wider and more immersive audio field from a compact speaker system, usually a single soundbar. Both JBL Multibeam and DTS Virtual:X are examples of this approach, but they take different routes to get there.

JBL Multibeam relies on a physical array of drivers and beamforming to steer sound waves in specific directions. DTS Virtual:X, on the other hand, is a digital processing technology that uses psychoacoustic algorithms to simulate the presence of surround and height channels without requiring as many physical drivers. Understanding these differences can help you pick the soundbar that suits your room and listening habits.

How JBL Multibeam works

Beamforming is a technique where multiple speakers emit the same audio signal with tiny time delays, causing the waves to combine constructively in some directions and cancel in others. JBL Multibeam applies this principle across a horizontal array of drivers to create broad, directional sound that seems to come from beyond the physical width of the bar.

Because it works with the physical arrangement of drivers, the effectiveness of JBL Multibeam depends on the soundbar's driver count and placement. A soundbar with more drivers and a wider cabinet generally can produce a more convincing surround illusion. If you are considering a JBL soundbar, look for the number of channels and the driver layout to gauge how well the beamforming might perform in your room. For a deeper look at JBL's specific implementation, see our explainer on JBL Multibeam.

How DTS Virtual:X works

DTS Virtual:X is a post-processing technology that can be licensed by any soundbar manufacturer. It takes a stereo or multichannel audio signal and applies filters and delays to emulate the cues your brain uses to locate sound in space. The result is an expanded soundstage with a sense of height, even when the soundbar has no up-firing drivers.

Because it is entirely DSP-based, DTS Virtual:X can be implemented on a compact bar with just a few drivers. However, its performance depends on the quality of the soundbar's speakers and the algorithm's tuning. Some bars offer both DTS Virtual:X and DTS:X, where the latter carries an actual height component if the content and speakers support it. To understand the difference between the two, read our DTS Virtual:X soundbar guide and the broader DTS:X vs Dolby Atmos comparison.

Comparing beamforming and DSP virtual surround

Both approaches aim to create an enveloping soundstage, but they have different strengths. The table below highlights the core differences.

What to look for in a virtual surround soundbar

Virtual surround is only one part of the experience. The physical channel count and the presence of rear speakers matter more for a truly immersive effect. A 5.1 soundbar with physical satellite speakers will outperform any single-bar virtual surround, as described in our guide to soundbars with rear speakers. If you prefer a cleaner look without satellites, consider a bar with virtual surround, but set your expectations accordingly.

Connectivity also affects what you get. To enjoy full-resolution soundtracks from streaming services and Blu-rays, connect your soundbar through HDMI eARC rather than optical or analog. HDMI supports high-bandwidth audio and video, which is necessary for lossless formats. Check your TV's eARC support before buying. For a step-by-step approach, see our HDMI ARC vs eARC comparison.

For wireless rear speakers or a subwoofer, Bluetooth and Wi-Fi are common. Bluetooth Classic is used for streaming audio, as described in the Bluetooth technology overview from the Bluetooth SIG. Many soundbars use Bluetooth for connecting a phone or a separate speaker. A stable Bluetooth connection is convenient, but for multi-channel audio a wired or dedicated wireless system is often more consistent.

Finally, remember that virtual surround can push you to listen at higher volumes to hear details, which can be harmful. The National Institute on Deafness and Other Communication Disorders warns that long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. Use the soundbar's night mode or dynamic range compression to keep dialogue clear without raising the volume. The Consumer Technology Association also emphasizes the importance of interoperability, so look for bars that follow industry standards for audio and video connections.

Choosing between JBL Multibeam and DTS Virtual:X

If you are deciding between a JBL soundbar with Multibeam and another bar that offers DTS Virtual:X, consider your room and how you will use the soundbar. Beamforming is better suited to rooms with predictable reflective surfaces, while DSP virtual surround can be more forgiving in odd-shaped spaces.

Look at the soundbar's channel count. If you are already planning to add rear speakers, the virtual surround method matters less because the rear channels will be physical. In that case, focus on the soundbar's core sound quality and other features such as dialogue enhancement and bass response. Our soundbar selection guide can help you weigh these factors.

For most people, the difference between JBL Multibeam and DTS Virtual:X is smaller than the difference between a 2.1 bar and a 5.1 bar with physical surrounds. If you cannot add physical rear speakers, both do a decent job of widening the soundstage, but you should manage expectations. The best virtual surround is one that comes from a well-designed bar with good drivers and proper calibration. Learn about virtual surround limits and physical rears vs virtual rears to set those expectations.

Questions

Which is better: JBL Multibeam or DTS Virtual:X?

Neither is objectively better. They use different methods, and the outcome depends on the soundbar's design, room, and content. A well-tuned DSP can sound great, and a beamforming array can be very effective. Listen to the bar in your space if possible.

Can a soundbar have both JBL Multibeam and DTS Virtual:X?

It is possible for a soundbar to include both a proprietary beamforming system and a licensed DSP mode. Check the soundbar's specifications to see which sound modes are available. Many bars offer multiple sound modes, and some may cross-combine them.

Does DTS Virtual:X require special content?

No. DTS Virtual:X can process any stereo or multichannel audio to create a virtual surround effect. It is not a codec like DTS:X; it is an enhancement that works on top of the incoming signal.

Does JBL Multibeam need up-firing speakers?

No. JBL Multibeam is primarily horizontal beamforming. Some JBL bars add up-firing drivers for height effects, but the Multibeam feature itself works without them. Check the channel layout to see if height channels are included.

Will virtual surround replace actual rear speakers?

Virtual surround can widen the soundstage, but it cannot replicate the discrete placement and timing of physical rear speakers. If you prioritize accurate surround, consider a bar with satellite speakers. See our guide to soundbars with rear speakers.

Should I worry about volume levels with virtual surround?

Yes. Since virtual surround can make effects seem farther away, you may feel the need to turn up the volume. The NIDCD advises limiting exposure to sounds at or above 85 dBA. Use the soundbar's night mode or dialogue enhancement to keep levels moderate.
