Specs seen to indicate it is a sealed box drive, and most of the line up above that, is designed for ported boxes.
The peerless drivers are quite good. Well made for the money.
Matching a new driver, in a three way, is a near impossible task. Don't bother unless you want to redesign the crossover, and learn that task from the ground up and over a decade or two...
If it involves a subwoofer application, then matching the sub driver alone is a great hassle and near impossible.
It will be possible to observe a difference, though, if you replace the given driver in the given system. beyond that, it’s all speculation.
Basically, whatever the application is...it is an in-situ integrated system, put together by experts. It needs to remain as such, in order to not compromise it’s performance.
By all means...go ahead and play if you want - learn about crossovers, and box design, etc. :)
With the caveat that you are dealing with an integrated system ...and messing with just a driver swap all on it’s own is usually (very high odds) a downgrade of a sort.
