You basically have a soft screen where you tv is. It will have no effect below about 125 Hz and probably robs your high frequencies. I would follow Rrog's suggestion about finding live and dead areas, but I would remove the blanket from the tv first.
Your room is very close to being square, which probably means you have some prominent bass peaks. There are things to recommend, but many are expensive and have low WAF. Our tv is quite large. I would recommend lighter blankets.
