Introducing SiriusXM’s newest boombox… The SXSD2

If you’re looking for a portable speaker dock to blast your Sirius or XM dock & play radio, check out SiriusXM’s newest boombox: The SXSD2. Released July 2014, the SXSD2 is arguably the best SiriusXM portable speaker dock on the market today.

Versatile, this boombox is compatible with both Sirius and XM radios by switching the dock adapters (included). This boombox will play popular radios like the Starmate 8, Onyx Series (Onyx, OnyxEZ, Onyx Plus) and many more. See the full compatibility list below.

Here at TSS-Radio, we’ve switched over from the SXABB2 to the SXSD2, and we’re loving it. Our initial thoughts are that we’re noticing a more powerful sound with a solid bass. The boombox boasts a 2.1 sound system with separate tweeters, midrange speakers and a subwoofer. We also appreciate the return of the simple turn-dial volume control knob as opposed to the fancy — but inconvenient — touch-dial on the SXABB2.

There are several ways to power the SXSD2. The traditional AC power adapter is ideal for home use. But if you’re on the move, you can power the radio with “D” batteries. Also, another advantage this boombox has over the SXABB2 is the ability to power through a car’s cigarette lighter output. You’ll need a 12 volt boombox power adapter (sold separately).

We’ve been using this boombox here in our offices for over a month now, and we think this is THE top candidate when it comes to a modern SiriusXM boombox.
