IRs that give you that thump in your chest

[flyingfadr]

Ubercab IR's... probably the cab with the most low end... or Mesa cabs, or those with greenbacks... IR's captured with a 121 will probably have the most low end...
If it's still not enough low end, buy a sub for your monitoring situation...
It should be fine for jammin at home alone, but will most likely not sit well in a mix, as you'll be stomping all over the bass and kick territory in the mix, but fun at home at window rattling levels... ;-)

For those that are recording - are you leaving the speaker thump on?

Honestly...I've not even looked at that parameter outside playing with it for a minute when released.
