Turning heads all these decades later, the Kilburn III Portable Bluetooth Speaker from Marshall is another example of how Marshall is continuing their legacy of timeless design and powerful sound. With the Kilburn III, you get portable convenience and a speaker that can handle being taken outside, with a durable water- and dust-resistant construction. You and your friends can put the Kilburn III anywhere, as its 360° true stereophonic sound can be heard clearly from any direction. It pumps out up to 50W of audio power that can be played for days with over 50 hours of playback time. Thanks to Dynamic Loudness, that streaming Bluetooth music will sound great at any volume, and with Auracast, you can share it with any compatible device that's nearby.

Share with Auracast

Auracast technology lets you stream audio to other Auracast-compatible speakers nearby, like a radio station, all without the chore of pairing to each and every speaker.

Dynamic Loudness

Marshall understands the joy of playing music loud, which is why they added dynamic loudness to the Kilburn III. No matter the volume you set the speaker to, it will automatically adjust the bass, mids, and highs accordingly to keep your music sounding perfect.

Also a Power Bank

The built-in speaker will give you up to 50 hours of playback, but it will also provide essential power for a smartphone, tablet, or other USB-C mobile device.

Made to Last

Marshall purposely designed the Kilburn III to last for years under normal wear and tear. You can even bring it to Marshall for servicing and the battery can be replaced over time.

Responsible Construction

The materials of the Kilburn III are eco-friendly and responsibly sourced, with 84% of the plastic used in the speaker being recycled. The speaker is also entirely PVC-free, wrapped in DMFa-free, water-based vegan leather, and has a post-consumer polyester backing.

Marshall Mobile App

Use the mobile app to manage playback, activate battery preservation mode, adjust bass and treble, download OTA updates, customize the tactile M-button on the speaker, and more.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is How long it will last? What will it look like after it rains? Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.

Wish I Had Used This Sooner – Stop Debating and Just Buy It!
Wish I Had Used This Sooner – Stop Debating and Just Buy It! After a lot of debate, extensive research, and way too many hours spent buffing my RV with other products that never fully delivered the results I was after, I finally tried Poli Glow—and I am extremely happy I did. My only regret is not using it sooner instead of letting other people's opinions talk me out of it. The difference in how my RV looks after applying Poli Glow is genuinely impressive. The high-gloss finish it lays down on the fiberglass is deep, clean, and long-lasting in a way that the other products I tried simply could not match. The application process with the included mitt is straightforward and far less labor-intensive than traditional buffing and polishing methods, which alone makes it worth switching to. The hydrophobic properties mean water beads and rolls off beautifully, and knowing the UV protection is working to shield the fiberglass from the relentless Las Vegas sun gives real peace of mind for long-term appearance and protection. For anyone who has been going back and forth on whether to try Poli Glow or sticking with whatever you've been using—stop debating, stop listening to everyone else's opinion, and just try it. The results speak for themselves and I won't be using anything else on my RV going forward. Highest possible recommendation.

Wow just wow. It works great.
I have a 2017 vengeance and it has had a bit of sun even though it stays in a building when not used. It was getting a bit of fading even though I polish it each year. I wanted to try something and this was what I settled one after looking. Yes it is a bit of work on a 43’ fifth wheel. I ordered 2 kits but after a week of working on it after work we went camping and where next to a week old fifth wheel and he asked what I used to make it look better than his. It has a mirror finish on it now. After 6 months it still looks great and it’s durable and ease of use. What an effective product
