I use one JL F113 in satin.
If I could predict that it would eventually become an HT-only sub, I might have gone for two lesser cost subs to go dual. I'm not such a sub nut to demand ultra linearity for HT purposes. For music, I would be more inclined. OTOH, SVS 13", MFWs, and the like didn't even exist yet.
In any case, the "smaller" size does give me more flexibility in positions if I ever did buy another one. I do not predict this happening any time soon, however. I have my eyes set on ceiling treatments and bipolar side surrounds as two of the more likely changes to come, if at all. (Bipolars for greater coverage in my multi row theater).
