Hello, I am considering a flightcase for my EBS 410 cabinet. It would be most practical if the cabinet could stay in the flightcase (so with only one removable front lid) I wonder if this will have a significant negative effect on the sound of this fantastic 410. How do you protect your speaker cabinets? a) In a flightcase which I remove when playing b) In a flightcase with a removable lid, the cabinet stays in the flightcase c) I only use a dustcover d) I don't use any cover/protection. Many thanks in advance.
