I found a better solution for the Bose F1 Sub Rolling Bag, The Gator GPS-715 Fits perfectly and has wheels, it's $159.00 add $20 and your speaker case has wheels!
For the Bose F1 812, I found a Duffle Bag with wheels that will fit snugly.
I got it from Ebags and it's $50/each added some foam inserts on the top and bottom, I added a BOSE logo on the side of the bag.
Hope this helps.
saw this thread having just brought an F1 system
then just purchased what I hope is the same case as yours
when I do a search for the gator GPS - 715 it comes up as the GPA 715 - just checking you put in the correct name ?😀
the store i brought it from are now telling me it won’t fit the Bose F1 sub
so I’m a little confused
look forward to hearing from you
