The TL1600 is a complete 5.1 home theatre system: four compact satellites, a centre and a matched powered subwoofer. Polk lists it as archived but keeps the specification page public.
A matched set for a first surround system. The four satellites and centre use small midrange drivers and tweeters in compact cabinets, and the subwoofer has an 8-inch downward-firing driver. The set needs an AV receiver; it is not self-powered apart from the subwoofer.
