toomanyspeakers Posted November 19, 2015 Share Posted November 19, 2015 Just finished installing the crossover kit in my Heresy 1.5 speakers. I ordered from Bob Crites. The speakers sounded good before the install. I have noticed better highs and a more clear midrange. Does this sound like what I should be expecting after the installation? 1 Quote Link to comment Share on other sites More sharing options...
minermark Posted November 19, 2015 Share Posted November 19, 2015 I remember my first new pair of Crites xovers, Scalas i installed them in. The sound after install was as you state, there was a difference, however upon aprox 5 to 7 hours of play (Burn-in) i really noticed a difference. Some people call BS on this, and have since the begining of time, they are you're ear's, you tell me after a few days. Someday i should ask Bob about what his thoughts are on the subject.

It's more likely your ears adjust to the new sounds than any component breaking in. Speakers do have a break in period but not capacitors. Someday i should ask Bob about what his thoughts are on the subject. You can, but I already know his answer. In fact if I remember correctly it's in his FAQ section on his website.

moray james Posted November 19, 2015 Share Posted November 19, 2015 so are people saying that capacitors don't form because that's just not so and that they don't sound different before during and after they form is most likely originating from people with low rez systems or ears or those who care not for stage and image qualities. The old "I can't measure any difference" is fine (what are you measuring?)but it often has little to no bearing on what you can actually hear. To say otherwise is like saying it matters not what grapes you use the wine will taste like any other wine. These arguments gets so old and tired. Boils down to either you hear a difference or you don't so do some experiments yourself because your impression is the only one that should matter to you.

From Vishay; Self-healing, also known as clearing, is the removal of a defect caused by pinholes, film flaws or external voltage transients. The heat generated by the arcing during a breakdown, evaporates the extremely thin metalization of the film around the point of failure, thereby removing and isolating the short circuit conditions. On Segmented Film Technology Capacitors, the self healing effect is more controlled. The film metalization is made by forming a pattern of segments, which are connected to each other by micro fuses. This limits the healing current and limits the self-healing effect to a well defined section of the film. The self-healing process requires only μW of power and a defect is normally isolated in less than 10 μs. Extensive and continuous self-healing (e.g. at misapplications) will gradually decrease the capacitance value. Sorry there is a burn in time, it's less than 10 microseconds.

Don Richard Posted November 19, 2015 Share Posted November 19, 2015 It's been a while since I've been out of school (46 years) but I'm pretty sure dielectric formation is what goes on with electrolytic caps. A positive DC voltage is applied to the cap's anode, and current flows through the electrolyte which forms a layer of oxide that is the actual dielectric of the cap. I have trouble understanding how: 1) A cap without an electrolyte can "form". 2) Any cap can "form" with only an AC voltage applied. If there is something changing in a newly installed cap that is not an electrolytic, it is certainly not dielectric formation that is responsible. Does anyone have an idea of what might be happening, or not? Quote Link to comment Share on other sites More sharing options...

You are correct forming is for aluminum electrolytic capacitors and does not apply here. This is why I referenced film capacitor documentation on "self healing", which is the only thing that will change in a film cap and usually only under misapplication.

Jim Posted November 19, 2015 Share Posted November 19, 2015 Bob told me straight up on the phone, that there is no break in time for the crossovers, and for the tweeters, maybe micro seconds. I have purchased both crossovers for my KG 4.2,Forte II, and tweeters for the KG's. Quote Link to comment Share on other sites More sharing options...
toomanyspeakers Posted November 20, 2015 Author Share Posted November 20, 2015 After several hours of listening I can honestly say that the highs are now more extended and clear. The midrange is also more clear. The bass is unchanged. Everyone has their own opinion but for me it was worth it. 1 Quote Link to comment Share on other sites More sharing options...
Don Richard Posted November 20, 2015 Share Posted November 20, 2015 After several hours of listening I can honestly say that the highs are now more extended and clear After several hours one's hearing changes. Professional sound guys will often wear ear plugs all day before a show so their hearing is fresh for mixing the show. Studio guys mix tracks at a lower level than one might think to keep fresh ears longer. 1 Quote Link to comment Share on other sites More sharing options...
