So I've got an R400B paired with R500/R50/R200C and a Denon X4300H. With the LFE crossover set at 120hz and the other cross overs at 60/100/80 respectively, the sub seems pretty muted. Upon running audessey it complained the sub was turned up too loud, so I had to adjust the volume on the sub down before running through the auto setup. This set the sub to something like -5db, and even despite changing this to -1db, it's still pretty unnoticeable (i.e. bassy but not shake the room ever). Am I expecting to much, or is this a setup issue?
