Perhaps their crossover needs a do-over like the Signature towers. The redone Signature towers were not bad to my ears, and they measured very well too.
What was the circumstance for the towers you tested? Did Fluance know they were being shipped for review?
(Rant on!)
You'll have to excuse my cynicism, but this is a company that does not seem to R&D their product very well (as reflected by the performance of the original sig tower AH began to review and, now, the bookshelf). They do not seem to be able (or care) to maintain quality control (as demonstrated by Dennis Murphy's crossover design that needed to be designed custom for the left and right speakers because the drivers were so inconsistent). They do not seem to care much about reputation (as demonstrated by their willingness to continue selling the "faulty towers" for months).
Their restitution program required the customer to have saved the original packaging and happen to check in on their website (or be a regular on forums) to find out about it. I don't believe they reached out to registered buyers (but correct me if I am wrong on this point)!
The ones I had did not have a "Made in China" label, but did have a little cloth Maple Leaf tag by the terminals as if deliberately trying to look like they are made in Canada.
All of this, together, makes me wonder if they would have entered the redesigned crossover into production if it added much more to the manufacturing cost, and no crossover is going to overcome the QC problem of inconsistent drivers. That is a hit or miss proposition.
So, I have to wonder if they actually reworked production, got their QC under control, etc.
The fact that they have not done anything to test/correct these bookshelf (which were made at the same time and presumably by the same "designer") leads me to believe they really don't care as long as they are getting people's money. All companies have to make a profit to survive, but some respect their customers and consider that part of their long term strategy.
I reviewed these speakers back in January with similar findings, but I hoped that once they got the towers ironed out they would turn those same resources to fixing the bookshelf sigs. Obviously Fluance does not see worth in that. Remember, this is
their flagship product!
