Montana big sky speakers

Probably just an 8 ohm speaker, just find one that will fit in the same space:

Here are the speakers I had in my Rv.

Speakers.

I just had to replace one

The OEM speakers that come in RVs are junk, anyway. I replaced the interior speakers in my travel trailer with Polk Audio just to improve the sound (and get some high frequencies so I could understand the dialogue in movies). When we purchase a fifth wheel for full-timing, I expect to replace the audio in the entertainment center altogether.

You might try calling Montana for info.

Its probably not the speaker, it may be the wiring in the back of the sound system came loose. I wouldn't think those speaker go out very often.

When I had my 2012 Samsung surround in my 2012 Montana one speaker gave out and i bought a whole used set on Ebay for 25 bucks AND let me tell ya folks My new 2015 Montana Legacy Surround is not Junk they use Sony 5.1 Surround/Blu ray DVD and Sony TV just like your home and it sounds AWESOME unlike other SOB's that use Junk Jensen or other cheap brand TV/surround

I certainly can't say for sure, but this is probably the company that supplies the speakers for you RV and most others.
