I have two old speakers with the code SS-LB455 with impedance 6 ohms. Do you know some good 2.1 amplifier that can drive these? I want to put them in sound card on my computer but they need an amplifier.
Looking at pictures of those speakers, they have strange wiring. They have separate wiring for a sub and speaker.
Your cheapest route would be to purchase a used older home surround sound receiver that can support your 6 ohm speakers. I believe most Onkyo receivers support 6 ohm speakers.
