I recently bought a pair of JBL LSR305 studio monitors: https://www.sweetwater.com/store/detail/LSR305--jbl-lsr305-5-inch-powered-studio-monitor
They sound great, but they only have a 1/4" cable input on the back. I'm mostly using my laptop and iPhone as an audio source so I bought this 1/8" to 1/4" Y cable: https://www.amazon.com/gp/product/B00ZKM3S4S/ref=oh_aui_detailpage_o01_s00?ie=UTF8&th=1
What I didn't realize is that this cable only splits a few inches before the 1/4" cable begins, meaning the speakers can't really be separated.
What's the best way to extend the range of the input so I can have these speakers sit on opposite sides of a desk?
