DRONE7

That sub looks like it may be a candidate for the Rod Elliot ELF treatment...if you're still experimenting then the minor cost and time to build and test may be of interest.
I discarded the 500W amp from my Monitor Audio Silver W12..
https://www.monitoraudio.com/en/product-...lver-w-12/
and replaced it with the ELF and (while still building an amp) a 100W class A/B.

Went from 'Punch..Punch..Punch'  to detail, speed, and extension.
Not a fan of fat and flabby ported subs.. 

There is a discussion of the ELF system followed by the current controller in the links..

Hi Bob , Thanks for your interest
Ill definitely try a sealed box for the sub, I built one for a previous system and liked it a lot , the driver is one of Daytons reference series so it is not a "one note wonder "
I went with sealed boxes for the bass drivers as I'm not a great fan of ports either, just wanted to give it a go with the sub

I don't much like that ELF filter, I suppose it could help some cheaper drivers but I'm not going to use it on this one
and a 100w A/B amp on that sub ?

I guess we all have our hangups
