I do not see the 2490 going any lower than 200 hz, I tested it in a 140 hz horn and in the 120 hz horn and in both tactrix horns the lowest it would go was 200 hz,  I think even if I put it a 100 hz horn it will still go down only to 200 hz, so I guess if I want to get to go as low as possible I would use a 180-170 hz Expo horn,  but as I see it maybe the best way to let it do its best will be a 200 hz tactrix horn and xover it at 250 hz and just let it run.

I do not see it right now as a susbstitute for the 10 inch driver (10M600) I am using since I do need the extra low frequency to 100 hz to match down to my current bass system.  So the 2490 will play from  say 250 hz up to about 1- 2 khz,  I will not get rid of the 120 hz horns  I will attemp a Fundamentals Channel with the 2490 running paralel to my current setup.

A the moment my system resolves all frequencies from 25 hz up to 40 khz with no fatal mistakes,  it sounds very detailed with good tone,  but it is missing a certain emotional quality,  I will try to add a bit more harmonics with the fundamentals channel on the musical range and see where that takes me,  this is unchartered territory for me but the better way to get there is to go...

I am getting the Studio 8M as a probable substitute for my current 10" drivers,  extending the throat of my 120 hz horns temporarily down to 4 or 3 inches for me is no problem,  if I find the Studio 8M to give some interesting attributes to sound I might make a specific horn for them depending on the results I get, maybe even a longer Hyperbolic or exponential horn;  I would love to get a couple of hz lower from them too,  I dont expect any big changes on my system with them,  but i want to be surprised!
