Two creative lab Satellite Speakers for T2900/T3000 system. Both working fine.

- each speaker has wire and has RCA connector.

- each speaker has a tweeter and a mid range.

I lost my subwoofer during moving. According to Creative T3000 specification

Satellite RMS Power /ea     6 Watts

so each speaker RMS = 6 Watts, you can hook up speaker to any RCA connector system as long as amplifier for each speaker is at similar range
