Might sound like a bit of an ambiguous question but how well does a sealed enclosure respond to EQ.
basically can the difference in extension between a ported enclosure and a sealed enclosure be made up with EQ easily enough? or will it require relatively extortionate amounts of amp power and excursion?

Very well within reason. Look at the sub equalizers on Elliot Sound Products and read about the Linkwitz transform. This is SOP.
I use an old Rane pro 31 band eq in line with my sub as I do basically the same thing but take the room into account. Easy and cheap. My preference is for a low Q sub and the eq is a bit of a hump. Others do high q boxes. I do not like the sound of a low Q box.

this question was regarding an AE TD15M, 87ltr sealed which gives QTC of 0.71(?)
gives -3db around 75hz, -10db in the 40's.
so if one was wanting to extend that extension so -3db was lower, realistically how much could I get out of it without having to go too wild. 75hz to 55hz @-3db?
i've never used a sealed box before so i don't really know how friendly they are.

PLEASE go read the references I supplied. PLEASE. Here, spoon feed.

With a sealed bass system you will need a very high class driver with low distortion. Bass reflex, TL, horn etc. make acoustic loading. EQ is electric and it easily leads to untolerable distortion. This is why vintage closed speakers had such "overscaled" 12-15" drivers.
6dB boost at say 30Hz is a challenge to many drivers.
Many driver manufacturers make different models of basically same frame and motor. This is because to make drivers to fit different loading. Check Qts, Le, and also Xmax. A difference in Xmax means that the "motor" is different. Studying any louspeaker catalog of a big name will help.
