Bag is well-built and fits speaker size, but the Velcro effect is causing a frustrating issue when trying to remove the cover. The material of the bag might be the main problem here, sticking to the speaker and making removal difficult. If this issue persists despite attempts to loosen the fit, I may consider a different cover brands like RCF branded bag, which might offer bags with different materials designed to avoid this effect. Alternatively, you could explore solutions like applying a non-stick surface or liner to the inside of the bag or the speaker, similar to the Teflon field/rhinoplasty. This could help reduce the friction and make the removal process easier.
