Acoustic treatment for corners.

If you mean that it will have the same acoustic properties as an open wall/corner, down to DC, no or not without Herculean measures.

Corners are notorious for bass reflections. Treat these areas and your bass response will improve.

Indeed. Corner treatment is effective and important.

Mmakshak, I have found corner traps to be very effective in my room. They are especially important where the walls are heavy and rigid (e.g., concrete blocks) and the bass reflects off the walls and the energy keeps reflecting around the room. A good corner trap makes the corner appear to be the same as if it were open to the outside or another larger room. It does not reduce the bass, but only the build up of modes.

Here is a link to a DIY article on how to build such traps simply and inexpensively. I chose the Super Traps which are described in Part II and made them with Thermafiber Safing Insulation which is available in local building supply houses. I recommend you buy the insulation and cut it into triangles as described and stack them in the corners to see if you like the change. You can try more or less at different heights. Then if you like the way it works, you can procede to build the front screens which are also quite simple.

See my system for pictures of the finished product. The total cost of both traps was under $150.
