上門調校?..It took over a year for my teacher to where it was acceptable, though not perfect. I have much less requirements compare to him, but still takes me at least a few months..guess we have different standards. O, well...he can sing some Italian opera.. without knowing the language....I had fun learning/singing some with him in English when I was 18 or 19..Lol...First one was Merry Widow..haha... in English, of course, not Hungarian.
The first pair of speakers that I know was DAHLQUIST DQ-10 in the mid 70s. Their phase array / delay correction made them famous with mid-range, tweeter, and super tweeter mount on different places of upper part of the enclosure, (dipole design, drivers independently mounted from front to back and left to right ) where lower half had a 10 inch sealed woofer. Result was great sounding speakers for the money at the cost of low efficiency. Ranks TAS all time number six. Second pair of good speakers which I killed the hf driver with clipping (first pair was Gale, winner of the CES show). Impressive specs for an old speaker system: (Not cheap then but peanuts compare to today's inflated hi end prices)
