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.

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.

I really don't see how anyone here is giving the OP a beating. But in all fairness, I don't see how anyone is giving him any useful info either. Your car example about losing power is very good. I may suggest your power loss may be due to the valve body in your transmission going bad. But you may have an manual transmission and not an automatic. I could also say that maybe the problem is in the ignition system. Wouldn't apply if you have a diesel. Maybe the wastegate is not functioning properly. Unless you have a turbo, there is no wastegate. I can keep going on all day, but you get the idea,

"What's wrong with the speakers from 2 yrs ago? Bad crossovers? Bad drivers?"

How on earth is someone supposed to figure something like that out if you don't even know what kind of crossover and drivers you are talking about?
