The HP 942836-001 rear-left speaker is a notebook replacement part for restoring the left rear speaker position in a compatible HP system. Its exact part number identifies it as the rear-left unit, helping distinguish it from the separately listed rear-right speaker.
The speaker is listed with a cable included, so the cable is part of this speaker assembly. The part listing associates it with HP Spectre 13-AE notebook variants, making it relevant for service of compatible systems in that family.
This is a specific speaker component rather than a complete speaker set; the listing identifies the corresponding right-side part separately.
