Bookshelf vs Floor-Standing Speakers: Which Suits Your Room

The real difference is air

A speaker's woofer needs air behind it to work against, and the amount of air decides how low the speaker can play. A bookshelf cabinet of ten or twenty litres, usually with one five- to seven-inch woofer, typically reaches down to somewhere around 45 to 60 Hz. A floor-standing cabinet of fifty litres or more, often with two or three woofers, can reach into the 30s and play the same bass louder, because several drivers share the work.

Everything else follows from that. Both kinds can have the same tweeter, the same midrange quality and the same imaging. Where they part company is the bottom octave, maximum level and how big a room they can fill before running out of steam.

Floor-standing: what the extra cabinet buys

Bass extension and weight. The obvious gain: deeper, fuller bass without a subwoofer, and the lowest notes of a pipe organ or an electronic track with real body.

Level and ease. With more cone area, each driver moves less for the same volume, so a floor-stander stays cleaner and more relaxed at high levels.

No stands. The tweeter already sits near ear height when you are seated.

The costs are size, price and placement. Deeper bass means stronger interaction with the room's standing waves, and a large speaker pushed close to a wall can turn boomy. Floor-standers also vary more than their category suggests: our reviews include a two-way closed-box floor-stander with fast, port-free bass, and one judged light for its class at 14 kg per speaker.

Bookshelf: what the smaller box buys

Placement freedom. A small cabinet is easier to position well: out from the wall, at the right height, angled at the listener. Imaging often benefits, because a narrow cabinet diffracts less sound off its edges.

Price. Money that would go into a larger cabinet goes into better drivers or a better amplifier instead.

Room fit. In a small or medium room, a bookshelf speaker's limited bass is often an advantage, because it excites the room's worst resonances less.

The trade is the bottom octave. For music with deep bass, or for home cinema, a bookshelf pair usually wants a subwoofer; our Taga Harmony DIAMOND B-60 v.3 review recommends one for home theatre. Active bookshelf models, with the amplifier built in, remove the need for a separate amplifier altogether.

The name misleads

Despite the name, a bookshelf speaker should rarely go on a bookshelf. Enclosed in a shelf, the cabinet couples to the surrounding wood and the wall behind it, which bloats and smears the bass and blurs the stereo image. Rigid stands that bring the tweeter to ear height, with the speakers some distance from the wall, do more for a bookshelf speaker than almost any upgrade. Where the port is matters too: a rear-ported speaker needs more space behind it than a front-ported or sealed one.

Choosing between them

Start with the room, not the speaker. A small room, or one where the speakers must sit near a wall, favours a good bookshelf pair, perhaps with a subwoofer later. A medium or large room, listened to at realistic levels, favours floor-standers. The site's room mode calculator shows where your room's bass resonances fall, which is the single best predictor of how much deep bass you can actually use.
