Looking for a DIY speaker kit? A kit gives you the drivers, a designed crossover and usually a cabinet, and you do the assembly, soldering and finishing. With no retail markup, the best kits sound as good as finished speakers costing several times as much. These picks are ranked on sound quality, not build satisfaction, from the 822 passive speakers ranked here.

Build effort varies a lot: some flat-pack kits go together with glue and clamps in an afternoon, while others ask you to source parts from several vendors and cut the cabinet yourself. Build the crossover exactly to the published schematic, since that is where the design lives; see crossovers explained.
Budget for the whole system. Several kits here need a reasonably powerful amplifier (see speaker sensitivity explained), and the open-baffle designs need subwoofers for full-range bass.
An excellent medium bookshelf speaker, a compact kit with remarkably accurate sound and good bass for its size at a great value.
Needs a capable amplifier, and it ships direct from the UK.
Open baffle floorstanding speakers with huge, enveloping imaging and very high sensitivity, easy to drive even with tube amps.
Very efficient, but it needs matching subwoofers and a lot of floor space.
A DIY kit bookshelf speaker with a ribbon tweeter for wide open, detailed sound, superb imaging, and tight, fast sealed bass.
Bass is tight but not deep, so plan on a subwoofer.
A DIY bookshelf design with exceptionally accurate sound that rivals far pricier speakers for a modest parts cost.
A true scratch build: you buy the parts separately and make the cabinet yourself.
A bookshelf speaker with unusually wide dispersion vertically and horizontally, very clean bass decay, and a neutral midrange that is easy to drive.
Sold as a kit or fully finished; toe it out a little to tame its bright treble.
A budget DIY flat pack kit with a 10 inch woofer and compression tweeter, built for home theater front or surround duty.
Plays loud on an ordinary receiver; sold in pairs as a flat-pack. The DIY Sound Group HTM-12 v2 that used to hold this spot is discontinued.
A build it yourself DSP speaker with a huge, open soundstage, little cabinet sound and surprising bass for its narrow size.
The kit price isn’t the whole cost: it also needs a plan license, a miniDSP and four amplifier channels.
An affordable flat pack bookshelf kit with a waveguide tweeter and high power handling that plays loud in a large room.
Easy flat-pack, but budget for a subwoofer and a capable amplifier.
An upgraded three-way DIY kit with smooth sound, wide dispersion and clean bass for a 6.5 inch woofer.
Sounds best with your ears near tweeter height.
A DIY crossover kit that fixes the main flaw of a popular Klipsch bookshelf speaker, with smoother sound and all new parts.
A replacement crossover for the original Klipsch RP-600M; it does not fit the RP-600M II.
