Bass issues,,,,will new speaker help?


Hi again.
When I am in rear corners of my room the bass is heavy but is hollow at my seat, when I measured my room with REW, calibrated mic and meter I have a suck out at around 50hz to 63hz (over 10db down at lowest dip).
My speakers have a woofer high and low plus a slot loaded passive, top woofer is 68in tall and there is another about at bottom of speaker.......speakers are placed very close to Cardas rule in a 14X24 room with low ceiling (79in), my seat is 6ft from rear wall.
I have a feeling of what answer is but just in case I wonder if a different speaker with a single woofer low to floor would change anything or if it is a case of bass traps and compromise......thanks as always.

Chad,

Perhaps the "Cardas Rule" will not work in your room. I'd try repositioning the speakers closer to the wall and if that fails I'd put them on an adjacent wall and experiment there. Why lock yourself into a certain speaker location because of some rule that apparently isn't working for you???
yeah, you are sitting in the worst spot in the room. room treatments may help, also, you may want to try adding a subwoofer into the system and fine tune everything with its placement.
I have the same issue. My dip improved (narrowed the troubled band width and decreased the magnitude of depth a a little) when I added a subwoofer, though still bothersome. It improved again (decreased dip magnitude a little more) when I added passive high-pass filters to my mains and reintegrated my subwoofer, though still -6dB. I hope to improve it once more when I add a second subwoofer.
