My Song 3 Encores took almost 6 months (5.7) from order to packaging and shipment. I don't remember the time from the 58% point to shipment. Sit tight. Be patient. Good things come to those who wait (well, within reason). I have two REL subs I used with my Salk SS 7M monitors (which I still have and intend to keep). With the Song 3 Encores, those subs are now unused. The extension of the Song 3 is good enough I really suggest you try going without first. Why deal with all the usual integration issues associated with subs if you don't have to. Unpack them, hook them up, break them in and let your ears be the judge whether you need to fuss with subs.
