I bought subwoofer from this company and that is my first and last transaction with it. Subwoofer Klipsch SPL-150 described as used but like new arrived with fault. Extremely loud inside noise from back panel or amplifier. I did make a video which clearly shows how it works and send it back to AV Online. After few days Av Online try blame me for that fault “because you not use uk power cable” and not refunded full amount. I have other Klipsch R-115SW subwoofer which works perfectly on this cable anyway I use both of them. Also I use Klipsch wireless subwoofer kit and cable for signalling it. I highly not recommended this place to buy pre-owned items, that was customer return not inspected properly. Avoid this place to safe your wallet and your peace of mind.
