I've been side tracked the past few days with work, life, but also room correction software! In short, I'm interested in it for correcting my office bass issues, very modal and peaky. I've played with REW making my own corrections and also a demo of IK ARC3. Listening to a corrected/flat response is pretty interesting. At first it sounds thin and tinny, but in short order your brain adapts. The measurements show large midbass humps in the room with several speakers i measured in the office. Listening to some speakers uncorrected in the basement today, i see it's given me some perspective.
Q Acoustic 3020i vs Ascend CBM-170 SE
I decided to do some more comparisons today and i first put up the 3020is against the Ascend CBMs as i considered these both fairly bright before. Interestingly, after listening to "corrected" sound for the past couple days, these don't seem super far off, particularly the Ascends. I guess i can spare you some words and paste in the notes that i took while listening. Remember these characteristics are relative to each other. I've given up all hope of storing a permanent reference in my brain.
crisp clear flat detailed
much sharper image
boosts female vox a bit
btbm kick drum and bass more clear
high end relatively rolled off
low end seems similar between the two
So in a nutshell, the Ascends sound more flat and more like studio monitors, except more forward. They almost sound "contrasty", like if you apply a lot of sharpening to an image in photoshop and take it just a click too far. They walk the crisp/harsh line. They have sharp imaging as well, vocals and instruments are pretty easy to pinpoint.
The 3020is are softer, a little held back. Even their sound stage is deeper back than the Ascends and a little smeared. They're not not detailed though. The tweeter sounds good, it just doesn't pop out like the Ascends. These are warmer and a little more pleasant to listen to, and i'm sure certainly so for long periods.
Ascends are the precise sports car that's a pain to daily drive, but when you want response and accuracy its there. The 3020is are maybe a base model 3 series.
