More shots from today's measurement session with EricH. Here are polars of the SEOS18, using a DE250 (driven with a series 100uF cap)
Horizontal:
Vertical:
Looks to me like it goes comfortably down to 800Hz. Here's a distortion plot at 2m, 90+dBSPL, no signs of distress down there.
For Penn, here's a shot of it being driven by his TAD 2001 (plotted along with the DE250 curve):
Goes both lower and higher, though EQ would take some more effort.
An overlay of the SEOS18 and the SEOS15 (both driven by DE250):
The 18 goes a little lower than the 15 (but pattern control to lower point is more significant)
I'll be trying to retrofit the SEOS18 into my ExtravaWaves (TD15Ms with homebrew 18" waveguide) sometime this fall.
