I have been using digital signal processing since 1995. It works incredibly well for subwoofer crossovers, full range room control and speaker balance but it has it's limitations. Doing this right requires the right room with all early reflection sites dampened depending on the type of speaker used. You do not want the frequency response drifting more than 5 dB up or down or you will run out of amplifier power correcting the troughs and drop resolution dropping the peaks. Newer processors like the Trinnov Amethyst and the DEQX Pre 4 and Pre 8 are so fast that running out of resolution is no longer a problem at any volume. These units measure, with there own calibrated mics, the frequency response, timing and phase of each individual speaker and subwoofer. They then flatten the frequency response curve, and correct group delays so the the sound from each speaker gets to the listening position at exactly the same time and in phase. Some of then will then overlay a desired target curve. I then measure the main loudspeakers with an independent calibrated mic and make any adjustment needed to get their frequency response within a dB of each other from 100 Hz to 12 kHz. The result is spectacular imaging which is the first characteristic that other audiophile notice.
Room correction room system vs ears….
So, I splashed out and spent more than I wanted to on a nice little Benchmark amp and preamp etc and since I’ve gone that far I got curious about a room correction system for this and it’s going to cost me over a grand apparently. As far as I can gather these dial in the music before it comes out of the speakers…?
im wondering if I simply messed around and found the sweet spot without a room correction system how much of a difference this would make. I’m far from savvy with audio and try to keep things simple for my simple brain, so, on a scale of 1-10 how much difference would I percieve by splashing out on a room correction system?
