Starting to treat my room... roughly 16' by 11', height 7'6". Of the four corners, only the front ones are treatable (due to door and 1/2 coda piano positioning). By 'front' I mean one of the 11' walls, where also the speakers are. Since I'm having pretty 'booming' sound I need to use these two corners at best, so my bass traps choice is between two Corner Mondo Traps (Realtraps), two ASC 13" TubeTraps (or SuperTraps), and finally two GIK Tritraps (I don't have space for GIK Monster Bass Traps). Price points are quite different between Realtraps and ASC (1,000 - 1,200 cdn $ shipped to Canada) and GIK (about 400 cdn $ shipped). Of course I will have to add other absorption treatment, but talking about bass trapping and considering I cannot use almost any other corner (maybe just one between ceiling and rear wall) which solution in your opinion could give me the best results ? Thanks
