Have you ever wondered what exactly “bookshelf speakers” are? As someone just getting into audio gear or setting up your first real stereo system, you may have seen bookshelf speakers mentioned a lot, but still feel unsure exactly what they are and what makes them different from other types of speakers. Well, let me explain what bookshelf speakers are all about in simple terms to help you figure out if they could be the right choice for your listening needs!
A Quick History of Bookshelf Speakers
First, a little background. Bookshelf speakers, sometimes called standmount speakers, originated in the 1950s and 60s as a compact alternative to large floorstanding speaker designs that were common at the time. Audio pioneers like Edgar Villchur and Henry Kloss, who founded Acoustic Research in 1954, developed innovative “acoustic suspension” cabinet designs that enabled them to make high-quality speakers in much smaller enclosures than people were used to.
Other companies like Advent jumped on board making their own compact bookshelf models, and by the 1990s and 2000s, amazing improvements in audio technology allowed even affordable bookshelf speakers to surpass the sound quality that only very expensive hi-fi systems could produce in decades past. Nowadays, you can get incredible performance out of small bookshelf speakers at pretty much any price point.
Breaking Down the Different Types
The term “bookshelf speaker” might make you think that they need to be squeezed onto an actual bookshelf. But there are a few different varieties that all fall under the bookshelf speaker umbrella:
Standmount speakers, also called satellite speakers, are designed to be positioned on speaker stands or platforms well away from walls. This allows them to radiate sound freely for optimal audio quality. Standmount speakers prioritize sound quality over compactness, so they may be larger than you imagine when hearing the term “bookshelf.” But they deliver incredible, high-end audio performance in as small of an enclosure as possible.
True “Bookshelf” Speakers
“True” bookshelf speakers are specifically built to sit directly on actual bookshelves, wall shelves, or to mount on walls. They emphasize compactness over performance, allowing you to tuck them neatly onto your existing shelves. But their petite size can limit sound quality, especially bass response. This makes them best suited for secondary rooms, not critical listening spaces.
Powered Bookshelf Speakers
Powered, also called active, bookshelf speakers contain a built-in amplifier to power the speaker drivers directly. This saves you from buying a separate amp. But you lose flexibility in upgrading your amp or connecting powered speakers into more elaborate audio setups down the road.
Wireless Bookshelf Speakers
These bookshelf speakers connect wirelessly via Bluetooth or Wi-Fi rather than speaker cables. This gives you flexibility in placement without wiring hassles. But sound quality depends heavily on the specific wireless implementation. The best wireless speakers still sound excellent though.
Satellite speakers are part of a speaker system that also includes a subwoofer to handle deep bass. The bookshelf speakers act as “satellites,” focusing on reproducing the midrange and treble. This is a common configuration for surround sound home theater systems.
What’s Inside Those Boxes?
To understand what makes a bookshelf speaker tick, let’s look at the components housed inside their wooden enclosures:
Enclosure – Bookshelf speaker enclosures are typically made of wood, MDF (medium density fiberboard) or plastic. Their construction impacts the overall sound.
Drivers – These are the elements that actually turn electrical audio signals into sound waves you can hear. The most common are:
- Tweeter – A small driver that reproduces high treble frequencies.
- Midrange driver – Handles the middle frequencies of the audio spectrum.
- Woofer – Plays lower frequencies, including bass. In bookshelf speakers, the woofer often covers both lows and mids.
- Subwoofer – Some bookshelf speakers include a dedicated sub for the very lowest bass frequencies.
Crossover – This circuitry acts like a filter, dividing up frequency ranges and directing them to the appropriate drivers.
Port – The port or vent is a tuned opening that enhances bass output.
Amplifier – In powered bookshelf speakers, the amp is built right in.
Wireless module – This allows wireless bookshelf speakers to transmit audio over Bluetooth or Wi-Fi.
Key Specs to Look For
When shopping for bookshelf speakers, you’ll see certain specs used to describe their capabilities. These are the main ones to look for:
- Sensitivity – This measures how efficiently the speakers convert amplifier power into sound volume. Higher sensitivity means the speakers play louder for a given amount of amp power.
- Impedance – Impedance is electrical resistance, measured in ohms. Lower impedance bookshelf speakers require more amplifier power to reach loud volumes.
- Frequency response – This spec describes the range of bass, midrange, and treble frequencies the speakers can reproduce. Wider is generally better.
- Drivers – The number and size of woofers, tweeters, and midrange drivers impacts sound quality. More or larger drivers allow for louder, richer sound.
- Crossover – The crossover frequency determines the transition between woofers, mids, and tweeters. Lower crossovers maintain seamless driver integration.
- Power handling – This rating indicates the maximum wattage a speaker can handle from an amplifier without damage. Higher is better.
- Dimensions – Bookshelf speaker cabinet dimensions affect sound quality and which spaces they’ll fit into.
- Weight – Heavier bookshelf speakers often use higher quality components and materials for better sound.
Positioning Them for Best Results
To get awesome performance from your bookshelf speakers, proper positioning is crucial:
- Place them at ear level, not down by your feet, on sturdy, vibration-isolating speaker stands.
- Position them equal distances from your main listening position, and angle them inwards slightly to create a wider stereo image.
- Keep them at least several feet from rear and side walls to avoid sound-muddying early reflections.
- Experiment with slight adjustments in angle and distance until you lock in the optimal sweet spot.
Investing in a quality pair of speaker cables is important too. Use at least 16 or 14 gauge cables with proper polarity between the amp and speakers. Allow a little slack in the cables to avoid stress on the connections.
It’s also vital to use a robust amplifier that’s up to the task. Match the amp’s output impedance and wattage to your speakers’ specifications. Underpowered amps lead to strained, distorted sound.
And don’t forget about room acoustics! Bare floors and walls create messy reflections. Adding carpets, curtains and furniture helps absorb sound for cleaner audio. Even well-placed bookshelves can help diffuse reflections.
Bookshelf Speakers at Work
Now that you know the basics of what sets bookshelf speakers apart, where can you put them to good use?
- For pure stereo music listening, a pair of high-quality bookshelf speakers flanking your TV or on stands in a dedicated listening room is hard to beat.
- They work excellently as front, side and rear surround channels for home theater. Add a sub to handle LFE effects.
- For your desktop computer, bookshelf speakers are perfect companions, providing immersive sound for movies, YouTube, games and streaming music.
- In commercial settings like retail stores, restaurants, and office lobbies, bookshelf speakers present background music or multimedia cleanly without dominating the space.
- In recording studios, bookshelf speakers serve as accurate nearfield monitors for mixing and mastering. Their compact size fits ideally into small control rooms.
Why Bookshelf Speakers Rule
Here’s a quick recap of what makes bookshelf speakers such awesome additions to any listening space:
- Their compact, versatile size fits into rooms where floorstanding speakers wouldn’t work.
- You can use them on shelves and credenzas without requiring stands or excess space.
- Properly designed bookshelf speakers deliver incredible, audiophile-level sound quality despite their modest size.
- They’re more affordable than giant tower speakers, making excellent sound attainable for almost anyone.
- Add a subwoofer, and bookshelf speakers can produce room-filling, full-range audio.
- They don’t need as much amplifier power as big speakers to reach satisfying volumes.
- You can choose from a huge variety of great bookshelf speakers at any budget level.
