Try and play with your EQ's. A little basic trick I do to tune mine is as follows. [Make sure you measure everything with ALL EQ's disabled/flat]. Write down the values of frequencies that your EQ has, then based on this generate a sinewave in a piece of software at 0dB fs going for about 2 minutes each for every frequency from the EQ. Once this is done, get a sound level meter, set your amps and whatnot to as loud as you want keeping the volume level set and sound level meter in the exact location all the time through the test. Play each sinewave frequency once, noting down the frequency and measured reading of loudness from each from the sound level meter. Once completed, create a bar graph using the data, with dB on the vertical axis, and frequency on the horizontal axis. When completed should look something similar to an EQ. This chart represents all the peaks and dips in your measured in room frequency response adjustable via your pre-defined EQ. If there is a peak in the graph on one of the frequencies, then lower that particular value on the EQ but whatever amount you deem necessary compared to on the graph. Whilst not an exact science, with a bit of experimentation and perseverance you can pretty much get your system sounding spot on, for very cheap. Detail and whatnot on the other hand is a completely different story.
