I found this: If I built a set using K-77 tweeters, I'd build DHA3s. The smaller tweeter cap reduces a bump in the response of the K-77 around 6k to 8k. Since the K-77 is really a 105 dB/w/m driver, the bulb and resistor form an L-pad in addition to tweeter protection. If you use Bob Crites' tweeters, or similar, you can use the DHA2 and maybe we'll need to adjust the 65 ohm resistor. 1 Quote Link to comment Share on other sites More sharing options...
