As an audiophile and home theater enthusiast, I‘m often asked whether it‘s better to have a subwoofer or a soundbar. The answer depends on your specific needs and setup. In this comprehensive guide, I‘ll compare subwoofers and soundbars across all the key factors – from audio quality to price and purpose. You‘ll learn how they differ, how to choose between them, and how to get the best possible sound by using them together.
How Do Subwoofers and Soundbars Produce Sound?
First, it helps to understand what‘s inside these speaker systems and how they turn audio signals into rich, powerful sound.
Subwoofers contain large driver cones surrounded by tuned enclosures. When fed a low-frequency audio signal, the cone rapidly vibrates, pressing against the air to create big booming bass notes. The enclosure reinforces certain frequencies and attenuates others to shape the sub‘s sound. They focus solely on deep bass, lacking the components to reproduce mids or highs.
Soundbars pack small speaker drivers plus integrated amps inside sleek housings designed to sit below a TV. The multiple drivers divide up frequency reproduction – dedicated tweeters for treble, midrange drivers for vocals and guitars, and small woofers covering upper bass. The amp provides power and signal processing tech like virtual surround sound. Some models even have cutouts or wireless subwoofer connectivity for adding separate subs.
Subwoofer vs Soundbar: Key Differences
With the fundamentals covered, let‘s compare subwoofers and soundbars across these critical categories:
Audio Quality
Subwoofers deliver tremendous low-frequency power and depth for a truly visceral listening experience. A well-designed 12" ported sub tuned to 20Hz can pressurize an entire room with window-rattling effects. Their focused bass provides tremendous impact for home theater soundtracks and thumping bass in music.
However, subwoofers must be combined with speakers or soundbars to get full-range sound covering mids and highs. Used alone, you‘ll only hear low thumps and rumblings.
Soundbars output well-balanced audio across lows, mids and highs in a single package. Models with advanced connectivity options like Dolby Atmos/DTS:X provide immersive, three-dimensional surround sound. Leading brands like Sennheiser, Klipsch and Sonos make soundbars rivaling audiophile speakers for detail and clarity.
That said, even high-end soundbars can‘t match enormous freestanding subwoofers for visceral bass power. Their compact form prevents huge bass driver displacement or extreme SPLs. Adding a separate subwoofer compensates for the low-end limitations.
Frequency Range
Here are the typical frequency ranges for subwoofers and soundbars:
Subwoofers: 20Hz to ~120Hz
Soundbars: 150Hz to 20kHz (some reach down to 40-50Hz)
As you can see, there‘s very little overlap – subs focus exclusively on bass while soundbars cover mids and highs. This makes them complementary tools suiting different sonic needs.
Number of Channels
This spec indicates how many discrete audio channels the device can reproduce.
Nearly all subwoofers are single-channel mono devices, meaning they mix down multi-channel signals to focus solely on bass.
Soundbars contain multiple drivers for multichannel reproduction. Entry-level models use two or three channels while advanced Dolby Atmos-enabled soundbars boast up to 17 channels. More channels allow accurate placement of audio effects all around the room.
So soundbars win for surround sound, while subwoofers are mono bass machines.
Size and Design
Subwoofers are large cube- or cylinder-shaped units designed to sit on the floor. Their enclosures house sizable bass drivers – 10, 12 or 15-inch models are common. They can stand over two feet tall while weighing from 25 to 100+ pounds.
Soundbars use slim, elongated profiles measuring 3-4 inches tall but up to 40 inches wide. The compact form allows placement in confined spaces like atop media consoles. Wall-mountable designs provide even more flexibility.
If you have limited space around your TV and want a device fitting seamlessly into your décor, soundbars are the obvious aesthetic choice. Headphone-toting apartment dwellers should look at compact subs like the cube-shaped SVS SB-1000 Pro.
Price Considerations
Entry-level soundbars start around $100, with superior models from Bose and Sonos costing up to $1500. High-output subwoofers retail anywhere from $500 to $3000+. You can spend some serious cash on hand-built audiophile subs from specialty brands.
In general, soundbars cost more than subwoofers for a given level of sound quality. However, adding a sub to a basic soundbar greatly bolsters its low-frequency performance for just a few hundred bucks. Take advantage of this cost-effective way to achieve big sound.
Intended Purpose
Here are the distinct use cases:
Subwoofers supply seismic bass fattening up music, soundtracks and games. They dramatically amplify a listening system‘s impact and visceral excitement.
Soundbars provide complete, great-sounding audio reproduction replacing TV speakers and smaller music systems. Their virtual surround technologies create immersive listening fields.
While a subwoofer handles the low-end and a soundbar covers the rest, both serve specific roles. Optimally, you‘d have both – subs are fantastic soundbar companions.
Key Takeaways – Which is Better for You?
-
Can‘t decide between a subwoofer or soundbar? Get both! High-quality soundbars like the Sonos Arc or Sennheiser Ambeo 3D provide gorgeous mids/highs while compact 200W subs like the RSL Speedwoofer 10S fill in the lows.
-
On a tight budget? Start with a value-packed soundbar like the Polk Signa S4 with wireless sub connectivity. Later down the road, adding a beefy sub brings heart-thumping bass.
-
Have lots of open floor space for big gear? Focus spending on an enormous high-end sub like the $1700 Monolith 15. Supplement it with affordable bookshelf speakers for astounding 2.1 sound.
-
Short on room space or need an integrated watching/listening solution? A single soundbar like the 120W Samsung HW-Q990B with its 11.1.4 channel sound can fill smaller areas with audio.
There you have it – a complete subwoofer vs. soundbar breakdown. As an experienced home theater aficionado, my advice is to ultimately own both for whole-home audio nirvana. Let me know if you have any other questions!
