Bass traps - too many choices!!


Browsed the forum and read a lot regarding bass traps. But overwhelming and still not sure what to buy. Looked at the ASC site; and their tube traps are tuned to different frequencies. eBay sells foam wedges which are advertised as corner bass traps. Relatively inexpensive too. But are they effective? I've also heard about using sand-filled cardboard tubes (used for pouring concrete). Even heard that a large potted plant set in the corner can be an effective bass trap.
Can anyone simplify this? I already have Room Tunes in my corners. Speakers are on the diagonal as my listening room is kinda squarish. So I'm just looking to put a bass trap in the corner behind and between the two speakers. But I want to make sure that whatever I buy is effective.

Ivan...you beat me to it. I was just going to comment on your above post. I’ve recommended and even tried the Cathedral Sound Panels myself, but they only work in a sealed room which most people don’t have, unfortunately.

IMHO, they still don't work as well as traditional materials.  YMMV.
If any are going to the Newport Beach Audio Show June3-5, GIK will have a demonstration room and will be glad to answer all questions. Good people with good stuff.

Auralex Lenrd bass traps are very effective and are based on acoustic principles.  I could not tune my room effectively without them.  They are also extensively used in recording studios.
I also use Auralex bass traps in four corners of my 11x12 foot room. Also use corner tunes. My room is together.

Mofi, understood. I tried them in a sealed room I had before my current room, which is now open floor plan, and they did pretty well, although the bass problems in that room happened to be not all that severe, at least not after I had gone through all the motions and given speaker placement its proper due first.
