Thank you all for not only responding but also for staying on point to my issue. I appreciate your taking the time to read about my issue and the time you took to respond. I will try to respond to all of you in one note.
NONOISE: My listening chair is a club chair that has some cushioning and it is about 8 feet from the speakers
LARRYi: I have been trying different speaker placements and do have tube traps. Per your suggestion I did move my listening chair back about 4 inches and it did help. I have been considering a subwoofer. I am not seeking booming bass. I want it to be natural and seamless with my speakers.
MILLERCARBON: My speakers are 62.5 inches from the front wall and 38 inches from the side walls.
MOTOKODUSANAGI: The speakers sit on rugs now and as mentioned above, I do have tube traps in the corners.
DWELLER: The platform you suggested sounds like a good idea. However, the speakers weight 200 lbs, and the base has a good size footprint
ATMASPHERE: As mentioned above, I have started researching subs, but have not looked at the Swarms. Thanks for the tip.
KLIKOMAN: Thanks for the idea of diffusers. I have visited the Gikacoustics site many times, but not the others you sent. I have no intention of changing speaker as I really like my Rockports and I am satisfied with my amp.
MTROT: Thanks for responding
