Bought several of these bundled with the K10 speaker - good Thomann bundle price!
I'll be taking the speakers on the road so wanted something to protect the cabinets. Overall quality is very good and the K10 speaker fits nicely into the bag with the front face down onto the base of the bag. The padding is adequate but it would have been nice to see some additional external rubber protection on the base of the bag to absorb knocks and bumps.
The dual zips make it easy to open the whole of the bag for easy acess to remove/pack the speaker and there is a velcro cover that can be opened to reveal the speaker's top handle to assist with manoeuvring when handling or packing into a vehicle or a tight space.
There is also a useful additional external pocket for mains cables, etc.
Overall a well thought out and designed bag - it's really a must have if you order the K10 and want to protect your investment.
I was aware that there were cheaper covers available but this cover was recommended by a friend. I am very pleased with it as it protects my speakers so well and makes them very comfortable to carry. Strong material and very good zips.
