It seems my questions were starting to hijack the sub-woofer discussion below.  :p

As suggested I've started a separate thread on the subject although I've only just learnt about the subject.

My requirement is that I would like to be able to quantify improvements to my listening room (and maybe others) after adding sound treatments such as absorbers etc.  Clearly I dont want to spend a lot of cash on this, because that would make the project a non starter.

I understand that to do this I need:
1) Freeware Room EQ software, which I have now downloaded http://www.hometheatershack.com/roomeq/
2) A USB Sound card (bit worried about the cost of this)
3) An SPL meter (it seems the Radio Sahck meter is relatively inexpensive.

Once I have this I understand that I would get the software to generate a sweep signal, which I play through my system via the sound card and RCA intelinks connected to my amp.
The SPL meter records the response at my listening position and I can then compare before and after plots to evaluate any changes made to the room.

Any other tips and hints would be appreciated.
