I bought a full stage source system a few years back and have been thoroughly impressed. Only been a little worried about transporting the gear.
Knew I had a bit of transporting coming up so I splashed out and bouth bags for the whole system.
The sub bags are great with the pocket for manual/ lead and a separate cavity for the post. cutouts make it easy to transport
THe L3m and L2m bags are exceptional quality with wheels and straps that don't feel flimsy at all.
The only con is the price, considering what I already paid for the speaker, I can justify keeping it safe but it was a deterrent in teh beginning. You won't find another bag that comes close to fitting this gear.
