lwang, please explain. When I think of 'sealed vs. ported' I think of an opening in a ported speaker that mice could crawl through (or ants), whereas a sealed unit is air-tight. I'm new to this and you seem to not be. So, please explain for all the newbies out there.
A sealed subwoofer is an acoustic suspension design. Both ported and passive radiator subwoofers fall under the designation of bass reflex systems. Therefore the Sunfires cannot be considered "sealed".
If your consideration for not having ported subs is so that your ferret won't climb in and nest there, then the Sunfire would be sealed. But as said, it having a passive radiator would make it act more like a ported sub than a sealed one.
You might be able to put a loose latex seal over the port if you don't want the sub to be infested with dead animals and insects.
