After much reading on this forum, I have finally gone with some recommended testing equipment.
In the past I have used a Radio Shack spl meter, cd, and Excel spreadsheet.
I have invested in a Behringer ECM8000 mic and preamp, I also got the cal file for this mic from Trueaudio. I used EFT5 for testing. I realise these mics are supposed to be good to 15Hz, but I included the 10Hz results as well.
I tested & eq'd my 2X M&K V125 subs which are situated next to each of my main speakers, and these are on one channel of my bfd eq. I then tested & eq'd my 1X M&K 5000 which is approx 2mtr behind me slightly out from the corner facing left to right i.e at right angles to the front subs. This is on the second channel of the bfd.
Listed are the results of all 3subs at once.

Now the question is these results are only having the subs connected directly to the computer via the bfd, so how do I test the system including my amp & main speakers?
Do I connect a Y adaptor to left & right tape in, and test the subs?. I don't want to blow anything up!!!
Thanks for any input!
