[QUOTE="Buffalohed, post: 2587519, member: 573552"] Thanks for the responses fellas. My question about THD was answered perfectly, thanks. I realize you can't take too much stock in published ratings, but it seems like a great thing to keep in mind when purchasing components for a system - keeping the overall THD low seems like a worthwhile goal for a SQ setup. What you (helotaxi) explained about power handling makes pretty good sense to me right now. The only thing is I have no idea how to determine any of those things about a sub. Are there any specific stats I should look for to indicate suspension overhang and motor efficiency and hence what kind of power would be required in an IB setup, or how easily xmax will be reached? The reason I chose Aura as my first choice was largely because of its top place in the 12" challenge, and also because I am worried about the output of only a single 15" IDmax or Q. I would be really interested if anyone can guesstimate if the Aura would work well IB. As far as the frontstage is concerned, that will be upgraded in due time as well, probably some time this summer, where I will be looking at getting Rainbow Platinums or something similar. Also would be thrilled if anyone has input on the other subs mentioned. And I'd like to re-word the question about IB... In order to fit a 15" IB my baffle will most likely be multiple pieces. Meaning it won't be a flat board, but will probably end up having a diagonal piece along with two vertical pieces. As long as the baffle is sturdy and the compartment sealed, is this something I should be concerned about? [/QUOTE]
