410 Farting out?
 

I know a lot of "farting out" threads exist, mostly due to people overpowering or playing through a bad cabinet.

I played a GK 410 MBE (the old model, the one I played is rated at 400 watss and the new one is rated at 800 watts I believe).

I played one at guitar center today, with GK's 200 watt micro amp at a conservative volume. No super deep lows, high mids, with a p bass and a pick.

The thing was farting out like crazy. It just didn't want any volume!

Although I'm not interested in this cab, I'm currently designing a sealed cab with Don from LDS.

To avoid my custom cab to do this, what causes a sealed cab to fart out. What can I do design wise (we have good drivers picked out) with the cab to prevent this?

The cab is probably already damaged from being driven too hard.

The 400 watt cab used 100 watt ceramic drivers and yes was probably hurt by someone.
Good drivers within a properly sized/designed/built box will go a long way.
