Midrange Analysis
Ideally, I would like to pick a driver based on these 6 characteristics
1. Personal Audition
2. Non Linear Distortion tests
3. Reputation
4. Frequency Response
5. Waterfall
6. T/S Parameters
The Problem is:
It is very hard to audition tweeters free of other influences- you pretty much have to buy the driver in question. Non Linear Distortion and Waterfall are rarely published. Reputation is subject to the bias, opinion, and group think of others. (I still rely on reputation)
Assuming we can’t audition or we want to limit our audition, we are left with T/S parameters (which are often wrong), frequency response, and reputation.
The question is: based on T/S parameters and frequency response what would you look for in a mid?
Some things I would look for:
1. Smooth frequency response in the passband+an octave above and below
2. No serious resonance within two octaves above the cutoff frequency(depends on XO slope)
3. A high Re/Le ratio
4. A high BL/Mms ratio
What other criteria would you use to evaluate a potential mid and how would you rank their importance?
I would also say both male and female vocals are the most important reproduction targets, and comments should reflect this.
I would limit the discussion to the mid in a closed box.
I am leaving crossover points open right now, because I would like more of a general theory and philosophy discussion.
Thanks a lot,
Mike
