[QUOTE="tangmonster, post: 165524, member: 1581"] ported makes the picture look much different. Driving the non eq'd ported design in a 190L box tuned to 19.84hz with 300W signal looks like this: you better make sure to have a high pass filter if you are driving it that hard :) [IMG]http://img.photobucket.com/albums/v287/tangmonster/portedxmax.jpg[/IMG] I left the other two at 30W making them 300W the excursion is roughly the same down to 40hz and then they just go up up up. At 300W the sealed design with EQ will start tunning out of xmax around the 38hz mark. Great for music if you ask me. with spl around the 110 db mark. [/QUOTE]
