Definitive Technology UIW RCS II 5.25" 2-Way Reference In-Ceiling Loudspeaker

  • Two cast basket drivers and pressure-coupled Low Bass radiators bring deep bass and high punch
  • Pure aluminum dome tweeter produces pristine high frequencies
  • Minimized visibility puts the focus on sound quality rather than the speaker
