Looking to buy a better sub for my 2 channel rig. Currently have a low budget Polk rm 6750 sub that's just annoying me. Does anyone out there use either of these in their systems, or have any opinions you would like to share? I know

2 Channel system:
Marantz 2330b
Dual cs 5000/Ortofon x5-mc
Nad c660
Sony scd ce775
Ads l1290
