35 passive speakers in our rankings are DIY kits: you buy the drivers, crossover parts and usually a flat-pack or cut-it-yourself cabinet, then assemble, solder and finish them yourself. Kits skip the retail markup and cabinet finishing costs, which is why several of them measure alongside finished speakers costing far more, but the build time, tools and any crossover soldering are part of the price.
A kit is a buying format, not a sound-quality signal; a speaker’s rank here reflects its measured audio performance, the same way every other passive speaker is ranked. If you want the strongest kits picked out and explained rather than every match, see our curated best DIY speaker kits.
This is every match, grouped by size and sorted by measured sound quality.
