What a difference curtains make...WOW

We just moved into a new townhouse with hardwood floors and a large view window. We placed an area rug in the middle of room. Here, I will not be able to have a subwoofer because people live in an apartment below our main floor (we have 3 storys, but an apartment is wedged between our lower level and main level). Since moving, my Polk Rti28's, I thought sounded tinny and bare. Our new, thick curtains arrived and I installed. Today, I turn on the stereo and WOW!! my speakers seemed like a whole new set. Bass was good, and everything sounded uncolored and natural. Wall/floor treatments do really work.
