Years ago I used to co-own a pro studio, and the live room was very large, as well as a beautiful vaulted ceiling. The floor was a dark stained hardwood (oak I think), and the largest wall was covered from the floor to about 10' up (of a total height of about 25') with thick, tongue and groove walnut. Beautiful room by any standard.
Recording vocalists and acoustical instruments really sounded warm and rich with the natural reflections, however there were times where we wanted to record something more dry. So along the wall with the walnut planking, we installed FOUR powered curtain rods, and we hung old stage curtains on each one. So depending how dry we wanted to record, we'd open or close one to four curtains. Stage curtains are massive in thickness and in weight, and absorb sound better than matresses, pillows, and ordinary curtains you'd buy in any home decorating store. We hung them floor to ceiling.
The other three walls of the live room had a lot of acoustical trapping and such so with the curtains closed, recordings were fairly dry. With them open, and adjusting the distance between the vocalist/musician and the wall with the walnut, we could increase/decrease the time of the reflections easily enough. Could also face the singer away, or towards, or to the side of the walnut for different sounding rooms at least to some degree.
Anyway, the point of my response is see if you can find stage curtains, new or used, they REALLY absorb sound fairly well across the full spectrum - even bass if you double them up.
