Is a parts unit worth buying?
The $649.99 parts price is $950.01 less than the $1,600 working asking price — a 59% gap. Whether that gap covers the cost of repair depends on what's wrong.
What "for parts" usually means for a speaker: Speaker pairs listed for parts often have one blown tweeter, torn woofer surrounds, or damaged crossover components. Sometimes it's just a missing grille or damaged cabinet.
When it pencils out: Surround replacement (refoaming) costs $30–80 for a pair of woofers — completely DIY-able with a kit. Tweeter replacement depends heavily on whether correct replacements exist. Cabinet damage is usually cosmetic. The $950.01 gap between parts and working price can make refoaming worth pursuing if surrounds are the only issue.
When to walk away: A blown tweeter with no correct replacement available is the parts-speaker trap. Original drivers on desirable speakers are often irreplaceable; aftermarket substitutes change the sound and hurt value. Verify which driver failed and whether correct replacements exist before buying.
DIY vs shop: Surround replacement (refoaming) is beginner-friendly DIY. Crossover rebuilding is moderate. Driver replacement requires matching the original specs carefully. Full repair cost context: what vintage stereo repair actually costs.
