I see this thread has been quiet for nearly 8 years, now; time for a resurrection! I own a pair of DQ-10’s, purchased them new in 1980 and I’m still enjoying them. I had Regnar rebuild them about ten years ago and am driving them with a Bryston 4b3, Ayre Kx5-twenty, my rebuilt Sansui tu-9900 and a Schiit Gungnir dac. I added in a Totem lightning sub with a new Bash amp; they sound amazing, go holographic even at low volume and when driven digitally, the bass is especially wonderful. The tweeter can be a little harsh, however and I’ve read about replacements. The Scanspeak, D2010 is still available, as are other tweeters. I’m writing now to ask if this is a worthwhile upgrade? Regnar did such a fantastic job that the original tweeters still look like new. And, as the crossover has been rebuilt by them, I don’t want to tweak it - I understand that by adding a resistor to the scanspeak, it will integrate as a 4 ohm driver. How effective is this upgrade and is it worthwhile? Are there any drawbacks? I’m hoping there are still people interested in this topic and that there are a few that might be a voice of experience. Any and all information appreciated! Thanks, John
