I'm surprised nobody reacted to this. These are the only T/S parameters for these speakers on the internet (to my knowledge) and these speakers are highly recommended on this fourm for mid bass. I digress.

In case anyone was wondering I designed a sealed and ported enclosure for these and .9cubes tuned at 56 worked well but couldn't handle anymore than 100w below 50hz without running out of x max.
For sealed the 50-100 hz range really suffered but with a .2 cube box they are able to take 175w without losing x max.
