@donavabdear ,
The microphones will be flat. They are calibrated when used for room correction.
The Lyngdorf should allow you to adjust the target curve. If you don’t find it warm enough, up the bass a bit, lower the mid-upper highs, and then adjust the mid-range to suit. You may get closer to what you like.
The imaging is likely better from a more consistent channel-channel frequency response and less distortion.
Also there is electronic DSP that creates optimized curves based on information from the way the speakers interact with the acoustics of the room, these curves will most likely not correspond exactly to all the other curves our modern systems have in them
The fundamental challenge in room correction is balancing these two conflicting requirements:
- As close to a flat direct frequency response as possible, at least from about 1-5KHz, ideally from 200Hz - 6 or 7 KHz for each speaker
- Consistent left and right channel room response
- A room response that is somewhat close to the researched Harman room curve that seems to suit most people.
DSP can only do so much. You need to start with an acoustically tolerant space.
There are other aspects of the audio signal that change the curve like phase knobs, separate EQ on subs, different pass filter fall off rates, built in EQ on preamps, A to D converters, D to A converts, etc.
I wouldn’t get too hung up on this. For one, if you are using passive speakers that are not time aligned, the speaker is likely the biggest contributor. Two, many room correction systems will do time alignment. Three, reflections make a mess. Last, four, we are not that sensitive to phase changes. Well researched area. In design, our critical measure is always no phase discontinuities. You never want the phase to change quickly.
No only are audiophiles confused but manufactures are confused because playback systems are not made like your ears, in electronics it is very difficult to not introduce feedback into the circuit for efficiency sake, so even at the base of a simple amplifier circuit we are already swimming upstream.
Are you implying electronic feedback is bad? Poorly implemented amplifiers are bad. Feedback is not bad.
I have went out and recorded choirs with 1 very good stereo microphone (multi microphones always have phase issues by definition) and plugged that direct recording into an amp and listened on 2 speakers (also a phase issue). The result is like eating a fish that you just caught out of a mountain stream, it is an entirely different test and experience than when you buy fish at the market.
Is it real or is it Memorex? When I was young, and would go to clubs, I hated when they had a band and preferred DJ. Now I would prefer a band as long as they are decent. Does age hone our skills to detect authenticity? I have always preferred a well recorded live album, but that is not a simple stereo pair microphone. Untapped market for artists that are authentically talented?
