My compliments to GR-Research and Danny for assessing my Dali Option 2 speaker and recommending the optimal upgrades. I have no prior experience with assembling a cross over network or even reading a wiring schematic. But after watching a number of You Tube videos and especially the Klipsch upgrade series on New Day Record I felt I could do it. Finding a way to get the cross over components laid out on a board that would fit inside my small speaker cabinet was the most challenging part for me, but it all worked out. It may not be the prettiest of work, but it was my first attempt, and everything worked! It probably only took me 4 hours total time to complete the upgrade start to finish. So for those of you that may be wondering if the effort and (small) cost of doing the upgrade yourself, I'd say go for it. There are lots of members at AudioCircle that no doubt could provide some help if you have a question.
For my speaker upgrade, I couldn't be happier with how they turned out. There was a very noticeable improvement in sound. In addition to the cross over components, I installed the No-Rez inside the cabinet, and added a 3/4 inch dowel inside the cabinet to brace the side walls. I also replaced the Dali speaker terminals with the Tube Connectors. And on this point, I'd highly recommend them. Even the "high quality" Dali terminals are nothing more than inexpensive plated cast metal - a lot of questionable material for the signal to pass through. The tube connectors are the next best thing to hard wiring the speaker cables from your amplifier to the network board. The way I looked at it, why use relatively expensive speaker cables only to connect them to very low-cost terminals on the speaker cabinet.
