Which speakers fit the space I have?

How the fit is judged

Every speaker must be smaller than your opening on all three axes, after the clearance you asked for is taken off the depth. "Room to spare" is measured on the tightest axis — a speaker with 2% spare is one you will be easing into place, not sliding in.

The bit that catches people out

Fitting the box is not the same as it working. 463 of the speakers we cover are rear-ported, and a rear port jammed against a wall raises the bass and blurs it: you get boom instead of the tuning the designer intended. Those models want roughly 20–30 cm (8–12 in) of air behind them. If your alcove cannot give that, a sealed or front-ported speaker is the right answer even if a rear-ported one physically fits. Any model needing that room is flagged in the table.

Two more things measurements do not tell you

• Grilles and feet add size. Our figures are the cabinet as the maker quotes it. Spikes, outriggers and a magnetic grille can each add a centimetre or two.
• A shelf is not a stand. Bookshelf speakers are named for where they end up, not where they sound best. If the shelf is the only option, favour sealed or front-ported models and expect to want a little less bass, not more.

Once you have a shortlist, the amplifier matcher checks what will drive them, and the placement tool covers where they should sit in the room.

Dimensions are the manufacturer's own, held in millimetres and converted for display. 387 of the bookshelf / stand-mount we cover carry all three measurements; any without them cannot appear here.
