Yeah, I HAVE ported JBL 2245 for home sub use, with a few caveats; I have never blown a single driver/system in my life, always had a pretty good sense how hard/loud I was pushing it; I don't run anything NEAR the rated input into most drivers; the sub is tuned to 28.8 and I don't try to get 20 hz; and I often use an amp with built in variable high pass, usually set to 30hz. Thanks for the reply.
