Paramour II - MagneQuest upgrade

Bear in mind that you can create a bit of a hump in the bass response just above the roll off point if you shrink the cap size too much. If that hits right where your bass boom is it could get worse instead of better. I'd consider reducing the cap size as a last resort and try getting the speaker to work with the room as well as possible first.

Yes, basically reading the above posts it would seem that further passive bass traps will be the order of the day as I feel (given my room dimensions) that a cap value change may be toying with the response below my problem area - I'll try and plot it this evening.  The impedance curve of the speakers seems reasonably benign with a minimum of 5ohms and a max of 9ohms from 10 to 500Hz (impedance curve supplied by the speaker designer) and nothing over 13.5ohms at all.

Doing some 'quick and dirty' measurements from the listening position with a basic SPL meter I would appear to have a significant 'hump' in output from 85-105Hz with the peak at 96Hz.

To know if any of that hump is due to the amp's frequency response you really need to measure the response of the amp into the same load that your speakers show it. It is most likely that the hump you are seeing is a composite of several room modes with the one at 96Hz being the worst. The place to start is to move your speakers a foot or two and see if the hump changes

Are the Pi Corner Horns like Klipsch Jubilees, with a side built into them?  That is, the Jubilees do not need the corner to function.

The room corner is integral to the design, this actually forming part of the bass horn.  The main reason I went for these was that fitting tight into the corners they take up less virtual floor space than my mini-monitors which like to be 3 foot into the room.  No I've come to the conclusion it's going to have to be more passive trapping but targeted at the mid 90's specifically.
