I am planning on buying a pair of AsciLab F6Bs, a WiiM Amp Ultra and a SVS SB-1000 Pro Subwoofer. Aside from power cables, it seems like I will need mono RCA cables to connect the Speakers and Subwoofer to the Amp. Is that correct, or is there something I'm missing? Do Speakers and Subwoofers require different types of RCA cables?
