Polk Audio MM651um in silver
The four stock speakers in the DWR Airstream were $16 coaxial pieces of OEM crap, unfortunately. For the kind of money a DWR Airstream costs, I would have liked to see a more premium speaker system be standard. But, that’s not the case. So, I went out and searched for a suitable speaker replacement that would fit the existing holes.
I found some great choices and ended up with the 6-1/2″ diameter Polk Audio MM651UM. This silver colored model is the Ultra Marine model for extra protection from sun, water and salt – for when we park this Airstream semi-permanently on a beach in Hawaii.
Given the mod white interior of the DWR Airstream, I didn’t want all black speakers. Silver works. White speakers of the quality I wanted were not to be found. I got four speakers for under $500.

I installed them in under 2 hours. I did have to drill a few new holes since they didn’t line up with the old speaker screw holes, but they look great and the sound is way better. My ears don’t get fatigued anymore and we can enjoy a more high fidelity sound while we are cooking and watching movies in the trailer.

Volvo XC90 with Dynaudio
Our Volvo XC90 V8 Sport on the other hand has a Dynaudio speaker system that still blows me away. WOW! When I used to be a audio mastering engineer, I edited on Dynaudio Acoustic C3 speakers and it was a pleasure.
So I say to Airstream: Please check out Dynaudio and see if you can have them customize a system for your trailer line. I would have certainly paid for the upgrade.
