What's wrong with my almost new speakers?

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?

Take your speakers to a clinic...they have an STD....

I agree completely with all of those whose responses have been prompted by the uninformative nature of the original post. Nevertheless, I'll describe two possible explanations that occur to me, although neither of them stands much chance of being correct considering that a zillion or so other explanations could also be hypothesized.

Theory 1: Many Focal and Harbeth speakers have considerably higher impedances in much of the treble region compared to much of the bass region. Perhaps the unnamed speakers have a flatter impedance curve. Perhaps you are still using the Rega Elicit solid state integrated amplifier you mentioned in a post 4 years ago that you were using. Or perhaps you are using some other solid state amplifier. Everything else being equal that would result in the treble region being more emphasized by the unnamed speaker than by the others, perhaps resulting in the presentation being more "irritating" (not "irratating") with many recordings. Perhaps the fact that the speakers were not broken in early in that one year period somehow compensated for that.

I know, there are a lot of "perhaps" in that theory, but given the lack of information that is inevitable.

Theory 2: The mounting screws on some of the drivers have worked loose over time, and the resulting vibrations are what is responsible. Be careful not to overtighten them, however.
