After a few short months of owning this unit the woofer separated from the voice coil. After calling customer service to have the unit replaced they said they only offer the original basslink and not the II for replacement. It's ok bass but they won't even advance replace after replacing the original with an inferior unit (according to themselves even). Shame on you Harman. New setup is Alpine SWR-1243D and KAC9105D. Booom...
