Hi, I'm using Soundstyles Z2 stands filled with atabites and am using some large Pioneer speakers on them with good success. The Pioneers are much larger than the BX2 speakers, so I think you will be fine. Alternatively, depending on budget go for the Atacama Nexus 6i or HMS2 (if you have the money). The HMS2 stands will be fine for any subsequent speaker upgrades. Partington also make good stands so try either the Superdreadnoughts, Trophy or Broadside. Hope this helps.
