How To Tell The Impedance of A Speaker

Long story short, if your speaker doesn''t have the impedance listed anywhere or you can''t find the manufacturer''s specs, the best thing to do is to measure it. That way you can be 100% certain and avoid problems with your stereo, amplifier, and crossovers. You definitely don''t want to use a speaker with lower impedance than expected as it''s possible to damage your
