A room is a note. Most people do not hear it, but they feel it — the room you talk quietly in, the room you cannot help raising your voice in. A speaker is a second note played against the first, and the pair either agrees or it does not.

So: match the speaker to the room. Not to the reviews, not to the price. The room.

Desks are high keys. A desk is one person at eighteen inches, and what it wants is detail — the reviewers’ word — resolved close. Bedrooms and offices sit in the middle, a warm key, a rug on the floor. Living rooms are low and wide and want a bigger driver that can hold a note without strain. Ask a small speaker to play a large room and it does two things at once: it goes thin and it goes loud. Owners describe this often. They mean the speaker was asked to be a bigger one.

The four below are sorted by room, which is the only sorting that matters.

For most rooms, the Edifier. The reviews describe it as warm, a little round in the bass, polite on top — G major, a comfortable key — and it carries every input a bedroom needs and a remote to reach them. It is the most-recommended powered pair under two hundred dollars in the expert lists, and the most-reviewed on the shop floor. At idle, with the gain high, some owners hear a faint hiss. Lower the speaker, raise the source. It stops.

For a desk, the Audioengine. Small, clear, resolving at arm’s length what larger speakers blur up close — A major, a key for small bright rooms with one person in them. The USB input makes a laptop the whole system.

For a turntable, the Kanto. The only pair here with the phono stage inside, so the record goes in one end and the room comes out the other. Bigger driver, bigger cabinet, and reviewers describe the bass as even rather than boastful — E-flat major, the key of living rooms with the lights half down. Give it air behind. Against a wall it goes boomy, and the owners say so.

And if you already own an amplifier, the ELAC, and stop reading. Passive, front-ported, a six-and-a-half-inch driver, and the owners’ word for it is smooth, which they use more than any other. C major. Nothing sharp in it.

One note on the sound these things make when no one is listening. A powered speaker is never quite off. It waits with a low hum or a faint hiss — a breath through the nose — and the better ones keep it below hearing. The Audioengine’s is very quiet; owners who listen for it mostly find nothing. The Edifier’s rises with the gain. The passive ELAC has no idle at all. It waits in silence, exactly, which is the rarest sound a product makes and the one I trust most.

If the room is too loud to hear any of this, the noise-cancelling headphones are filed nearby, and if it is too quiet to sleep in, the sound machines are one file over. The kettle, reviewed here, is in E-flat and will agree with the Kanto.

Three of these resolve. The Edifier resolves in G, the Kanto in E-flat, the ELAC in C; you will stop hearing them, which is the point. The Audioengine keeps asking a small bright question at eighteen inches, and on a desk, that is the right thing for a speaker to do.

Questions, anticipated

What is the difference between powered and passive bookshelf speakers?

Powered (or active) speakers carry their own amplifier — plug them into the wall, connect a source, done. Passive speakers need a separate amplifier or receiver and speaker wire, which costs more and sounds, per the testers, more, if the amplifier is any good. If you do not own an amplifier, buy powered. If you do, the ELAC below is the better speaker per dollar.

How big a speaker does my room need?

Match the woofer to the room. A 2.75-inch driver (the Audioengine) is a desk speaker; a 4-inch (the Edifier) fills a bedroom or office; 5.25- to 6.5-inch drivers (Kanto, ELAC) fill a living room without strain. Owners who put a desk speaker in a living room report it going thin and loud at once, which is the sound of a speaker asked to be a bigger one.

Do I need a subwoofer with bookshelf speakers?

Not for music at ordinary volume in an ordinary room; the two larger pairs here reach into the 40s of hertz on their own. For film, or for bass you feel in the floor, yes — the Edifier and Kanto have a subwoofer output for later, and the ELAC pairs with anything a receiver will drive.

Can bookshelf speakers connect to a turntable?

Only if something provides a phono preamp — the turntable itself, a separate box, or the speaker. Of the four, only the Kanto YU6 has one built in; the others need a turntable with its own preamp (many now have one) or a $30 external stage.
