Sony, JVC - STR-K670P + SP-UXTB3 Hi-fi set

This combination consists of the Sony STR-K670P, a powerful 5.1-channel home theater receiver, and the JVC SP UXTB3, compact bookshelf speakers from a micro system. The Sony receiver delivers quite a bit of power (60 to 100 watts per channel) and is optimized for a minimum impedance of 6 ohms. Because the small JVCs usually have a lower power handling (often around 20-40 watts) and are specifically designed for small rooms, you should be careful with the volume control to avoid overloading or blowing the JVC speakers.

Sony STR K670P:
Type: 5.1 Channel Audio/Video Surround Receiver
Power Output: 60W per channel (Stereo) / 100W per channel (Surround) @ 6 Ohms
Formats: Dolby Digital, Dolby Pro Logic II, DTS 5.1

JVC SP UXTB3
Impedance: Typically 4 or 6 Ohms (standard for JVC micro systems)
Power : Approx. 20 - 40 Watts

The set works perfectly.
