NoAudiophile DSP Correction Overview
What are you doing?
Easiest explanation is that I'm adjusting the frequency response flat by turning down any peaks to bring it all down to the lowest output level that is just acceptable to me. I also listen, alot. I spend more time with these cheap speakers than I do my main rig, corrections can take up to 300 hours of listening and working with measurements. I also tweak and update corrections to fine tune with new tactics I've discovered that produce better results, the more confident I am with my measurements the more accurate I can get.
How do I use these corrections
Instructions are on every correction page, also a MiniDSP should work in a system that does not have a PC.
How loud are these speakers before you correct them?
This is with the volume knob in a fixed position on my test rig. Note that a 3.7ohm Micca is going to pull twice as many watts as the 7.6ohm OSD AP490 from the amp for a fixed measurement.. so this is not a perfect graph, but it will give you an idea of what to expect. Note that these are smoothed 1/1 in an attempt to show average spl level.
How loud are these speakers after you correct them?
Dude, Flat sound like ass.
Dude, some people prefer color in their sound. I've got a menu for that, to add color back into the corrections for that transparency, speed, attack, clarity, etc. that audio reviewers go on about.
These are the secrets that I've unlocked so far. I have not found them to universally work for all speakers. Use at your own risk, goofy sounds can be addictive.
Also remember to use the preamp level to cut it make sure there is no gain added to the digital signal, digital distortion is real and it's ugly.

So what do I do now?
Buy some cheap speakers, and apply the corrections. Also, if you are in a giving mood you can email me to let me know what you really think.
