-- perhaps one thing is that RTA won't tell much with regards to "quality" - you can lay mic on the floor for sub, maybe 1-2M on-axis for midbass
System 100 midbass w. 250Hz cone-drive tractrix
System 100 midbass outdoors with two different type driver (btw - the low sine distortion on the graph was with K43 type - 2220H had higher H2) 2220's rise to peaking around 2K can be seen

Hi freddyi,

I suppose the first thing I'm looking for is to try to get a feeling for what the midbass is doing as the impedance begins to swing up.

Do you think the room interactions will make much of a difference?

  dunno - probably to some degree - in a little room I cna't get graph without some suckout - whats your midbass's driver?

    Yeah, I guess I'll just have to try it and see what it looks like. The driver is an EVM Pro-15B.
    
    I suppose if push came to shove I could rig up a sled and rope slings like the piano movers. Then I'd just have to bribe my son into stopping by to lend a hand. ;)
