Sealing ported enclosure to reduce boom

Is sealing ports and adding fill an option if you have ported cabinets that are boomy? Just got some Kappa 8.1 and bass is boomy and unrealistic. I like my Kappa 7 better which is sealed but the 8.1 has some interesting drivers.

"Sealing" the port is a bad idea. The drivers and crossover were designed to work with the port open, at least to some degree.
Knownothing, how would it affect the crossover?

Here's an example what you're effectively doing when a port is plugged.
