Bass traps: RPG Modex Corner vs ASC Tube Traps vs?


Hi, I am looking to add some bass traps to my room. I am thinking about either the RPG Modex Corner or the ASC Tube Traps. It appears from the data that the ASC Tube Traps have a higher absorption coefficient than the RPG Modex Corner but it is difficult compare because the Tube Traps are 4' tall and the Modex Corners are 2' tall. I was thinking about stacking 2 Modex Corners but I am not sure if doing so will significantly increase its absorption abilities.

Has anyone tried either or both of these products? Is there anyone else I should be looking at?

Thank you,
Tommy

Look at GIK Tri-Traps. They are are new to the market. Haven't done comparison, but numbers are good. They are basically panel-type traps with triangular pieces added to top & bottom for cornr mounting. Very attractive price to perfomance ratio.
Thanks Beavis. I am have looked at them and their absorption figures are impression. The price is really nice compared to others. I dont know anyone who has purchased them so I am reluctant do it.
I second the Realtraps Mondo traps........ I have them (along with some other Realtraps stuff) in my room and am very pleased. The price/performance ratio of these products is very good.
