What's wrong with my almost new speakers?


I purchased a pair of new speakers less than 2 yrs ago. They sounded just fine to begin with, but within 1 year they became "irratating" after a short listen. I have purchased new speakers since then from Focal and Harbeth, and both of these pairs sound wonderful. What's wrong with the speakers from 2 yrs ago? Bad crossovers? Bad drivers?
We do not listen to music at loud levels.

Seriously Drubin?

The sarcasm has nothing to do with the brand being mentioned or not. The
question is ridiculously vague and unanswerable.
It is a vague question. Answering vaguely, sometimes we are attracted to a piece of equipment because it does one thing so well that it immediately grabs our attention. Over time, we discover that the one strength masks shortcomings that, in the long run, prove to be annoying and ultimately make us want to stop listening. I doubt that the problem is in the crossovers and the drivers, unless their design was flawed to begin with.
I wouldn't rule out issues pertaining to the quality of the OP's electrons. I maintain robust reserves of quality electrons just in case ....

Another reason someone might be reluctant to specify the product in question is that, regardless of the eventual outcome, it can create a negative impression for the manufacturer. It's fair to ask the OP's question without specifying the brand. Not ideal, but not worthy of all the sarcasm you guys have heaped on him."

Its not about that. The OP asked us for help. Knowing what the entire system is can go a long way in terms of finding a solution. Customer problems are business risks for any company. Its like having your car break down and not telling the mechanic what kind of car you have.
I don't want to make a big deal about this. I get that it's vague and hope the OP will circle back and provide some more detail, if he's survived the beating y'all have given him. Re: the car trouble comparison, I could ask what would cause my car to lose power and you could suggest some things without having to know what kind of car it is. That's all I was trying to suggest.
