Update on Dulcet speakers:
I was informed by the President of Reference 3a that the new Dulcet speakers have further improvements and upgrades other than the upgrades I mentioned which I installed myself. Unfortunately for the DIY type, these new upgrades can only be done at the factory. Based on the improvements Tash said I would experience with these new upgrades, I took my mid/woofers out, carefully packed them and shipped them back to Reference 3a for the upgrades. The upgrades include:
1. VC Gap/Air isolation
2. new voice coils
3. cone lamination
4. Edge hole
5. AVM treatment
Tash returned the newly rebuilt and upgraded woofers in less than a week. Extremely fast shipping. Even though the new woofers need some time to break-in, the new sound is absolutely glorious. Better in every respect: imaging, transparency, speed, palpability, flatter frequency response, better dynamics. Music sounds like it is now much closer to the real thing, like more veils have been removed, and the sound was already magnificent before the upgrades. I am very pleased with the results and the upgrades were priced very fairly and overall a great bargain. Again, for those who have older versions of the Dulcet, and you have been happy with their performance, I highly recommend taking advantage of these upgrades. Bravo, Reference 3A and thank you Tash, Diane, and the crew for your excellent communication and impeccable service.
