All my observations were done within the dealers listening room. All three subs were place in the same corner and hooked up to a Marantz receiver in the same way (LFE out). The crossover was adjust to 60 and 80hz. I took it by this that their sound was inheirant to their design and not a matter of placement, though placement could have improved responce. I would think the REL capable of such frequencies, perhaps it is not able to compress the air in the room enough, however there is also the very deep base which is lacking. However, if I was watching a comedy with no action I would prefer the REL over one that would bombard me with bass.
