The Tad's R1 + Cr1 are real world class speakers. I am professionaly involved with some high-end distributors, and have the opportunity to hear the mayor part of top speakers on the market ( no names, please..).
But this is not surprising, considering the long story of Tad, and the highest quality of the woofers, drivers and tweeters used in the most famous recording and monitoring studios in the world.
Even today, the quality of the professional production of TAD does not fear comparison with any other brand of single components/speakers used in the consumer market!
I am not a tecnnician, and can only admire the fantastic project about the R1 and Cr1. The dual concentric beryllium speaker has not equals, and the woofer are from the same, highest, level.
the cabinet is beautiful and well made, it cost's a lot in manifacturing!
Still less I cannot understand the presence of a resistance of this (low) quality in a such crucial point!
You have to consider that all the sound for the midrange passes through this single component!
I can only repeat that the improvement obtained by this simple change, it is amazing.
Highs, midrange and even, unbelievably (!), on the bass quality.
This means that the quality of the project itself, but also of the major components such as dual concentric is really.. stellar.
If one is interested.. I can send a p.m.
I am not sure this is the right place for an un-official tuning project...
Alexis, could you post a step by step DIY as well as the part numbers. This sounds like a very exciting upgrade to what is already a world class speaker. Has anyone noticed that J. Valin has recently commented about the TAD's. Even with all the new great spier speakers he has been anamoured with, I believe his comments elude that TAD's stand the test of time as one of the top performing speakers in the marketplace, rather than suffer the fate of other flavor of the month designs.
