I have been told that Quad 2805/2905s were made with less than
perfect panels. 989's are also said to be problematic. $550 per each panel replacement, freight two ways and multiple panels-therein lies the rub.
You may in fact need to sets of speakers as the expression "Have Quad will Travel" may apply. After I fell in love with the sound of a 2905 at a fellow club members home, I started hearing from the only two
people I know who owned them about the issues they were having. When Scott told me about the issues he deals with on this model,
I decided I need to look in another direction for new speakers. The good news is that Scott says the new panels are much better now. He has yet to see any issues with the next generation 2912s. I hope this helps some
readers.
