No, but there IS a comparison between the SVS SB-13 Ultra and the Rythmik F15HP. I don't recall where I saw it, but a Google search should bring it up.

I didn't compare the SVS SB-13 to the JL Audio E112, but I did compare the SVS SB-13 to the JL Audio F110 v2. The comparison was done in my system. I compared dual SB 13s to dual F110 v2s. I hate to admit it, because I thought the SB-13 Ultra would do better, but the F110 v2s were better in every way.
