Thanks for the reply,<br />
<br />
I decided to go with a sub up, port back config in my trunk setup for the woofer, one of the reasons being I couldn't get anyone at Sundown to help me figure out the T/S parameters on this re-coned Nightshade (has an extra stiff spider) so I would pretty much have to guess at them... which is exactly opposite what you want to do when designing a bandpass... or any enclosure for that matter lol!<br />
<br />
Thanks though!
