cool, no worries. I think I am going to have a play with dsp. I just don't know what I am doing!
my big tannoys sound better out from the walls, but practically they need to be either side of the alcoves. I want to see it correction can get rid of some of the bass bloom.
BRM-
I'm trying to read a book called Master Handbook of Acoustics, it's pretty dense but it does give a lot of information about speaker positioning, room modes etc. It's complicated but one thing they do warn about is having the woofer at the same distance from the wall and the floor, apparently that's the axis of evil! Another aspect of the wall bass is a deep notch at 100hz which is hard to fix digitally.
I'd not had any problems running the LB1's with a Cambridge A1 but had never noticed how weak the bass performance was until I tried the Hypex amps and suddenly the bass was overwhelming, almost painful after 10 minutes. I'm thinking of making a small butterworth resister/capacitor network to put on the output cables so that I can go back to an analog solution but I need to decide on the values. At the moment I'm using a shelf filter in the MOTU set at 98hz -4db and that is sorting them out. Next step is a calibrated mic to check the room responses.

It had been on my mind but I've ended up with a slightly different setup at the moment and I'm running the cnc diy phono stage into a digital rig with 2 hypex amps and PMC LB1's or Dynaudio air 20's through a Lavry AD which has a tube saturation feature with a MOTU 8D for digital mixing/dsp. All to get around a +4db bass problem with the speaker positions!
I also just got a PMC Sub 1 to go with my TwoTwo 5's on my desk setup and that's forced me to rethink the other rig a bit. So I'm basically still interested but super busy on both rigs too.
