It really depends on how you're going to mount it. A Monster straddling a room corner will do as well or maybe even a touch better than the Tri Traps. On the down side, they're more expensive as they only ship 1 to a box and they're also going to eat more space in the room. The back of the Monster will touch the walls in this configuration where the Tri Traps stop. Then the Monsters come out another 7.5" from there.
Now, if you can't get a 45 degree straddle due to a door frame or whatever, then they're certainly a viable option with good performance.
If you're going to mount them flat on the wall, they're still pretty close to the Tri Traps in extension even without any gap behind them other than what's already built into it. If you had another 2-3" behind them, then you'll certainly get some benefit.
