Thanks for the reply! For the most part the stf-2 is great but it lacks extension and it bottoms out on low bass content. I'm only looking for more output below 23hz where my curve begins to drop rapidly. From 23-20hz my curve drops 8-10db. That is with the correction file loaded.

I was checking out the pb12 earlier and it looks like a great sub. I was leaning toward the cylinder because I don't have space constraints and I thought it had a distinct advantage in output and extension for only $50 more.
