The first universal Sirius boombox has been spotted by the eagle-eyes over at Sirius Backstage. Remember, this is the first glimpse of the upcoming Sirius' Universal Plug and Play Boomboxes which will have support for not only the Sportster 4, but also the Streamer 3 and the Sportster 3 (which has been talked about, but as of yet not seen).

The SUBX1 Universal SIRIUS Boombox will have a built-in amplifier plus speakers, and will feature an auxiliary input for other audio devices. Included with the boombox is an adjustable indoor/outdoor windowsill antenna with 20' of cable and an AC adapter.

The price listed on GoPremco (where the photo was originally discovered) is $359.99 for both the Sirius Sportster 4 and the Boombox. So minus the $169.99 for the Sportster 4, that would bring the Boombox to around $190 (yeesh).

Welcome back, hope everyone had a great 4th of July weekend (I'm still recovering). And just to welcome us back, Directed Electronics has filed an 8-k, that confirms what we heard about the mysterious missing Sirius units. Apparently the Sirius S50 and the Starmate Replay FM transmitters are not in FCC compliance. Directed received a letter on 6/30 notifying them of this.

In a recent report by Bank of America analyst Jonathan Jacoby, he suspects that Sirius' plug-and-play receiver shipments "ended on 6/23/06." Interesting.
