First time restoring a pair of Heresy’s…and I messed it up


Recommended Posts

Picked up a pair of Heresy IIs a couple months ago and fell in love right away.  I decided to give them the full mod/restoration.  Dynamat on the horns, new titanium tweeters from crites, recap the crossovers with sonicaps, little bit of polyfil and refinished the cabinets.  They look fantastic but unfortunately they sound like crap.  I did something wrong with the crossovers and I’m too inexperienced to figure out what.  
 

These are the early Heresy IIs which have the rats nest mess of crossovers.  I almost sent them in for the recap, but I decided I could handle it.  Apparently I couldn’t.  I did them one at a time using the other as a guide and was very careful to make sure everything was exactly where it should be.  When I put the speakers back together they sound like there’s a blanket laid over them.  Everything sounds muffled and distant.  Each speaker sounds the same so whatever I screwed up, I did it to both.  Anyone wanna weigh in and tell me what they think might have went wrong?  I realize it’s not the easiest thing to diagnose via a forum post but a shot in the dark would be appreciated and might save me from having to cave in and buy all new crossovers or send them in to have them fix whatever stupid thing I did.

They sent you a schematic with the kit, right? You will need to trace everything out. It sounds like the tweeter is being shorted, so start there and work backwards. Make sure none of capacitor leads are touching each other.

Yes they sent me a schematic and I had a crossover on hand to compare it to.  I’ve looked over both extensively and I can’t figure out where I went wrong.  The schematic is difficult to follow in this instance because the crossover itself is a jumbled mess.  It’s difficult for my inexperienced brain to compare the schematic to what’s happening on the crossover itself.  
 

Anyway it doesn’t matter now because I sent it to Crites this afternoon to be done right.

Thanks for not sending it to me, I think I’ve had my fill of those. 
 

Don’t beat yourself up. Those things are a bear, even when you are used to doing them.

What do you mean by "sound like crap"?  That could be many things.  Too bright?  No highs? Etc.  Could be those Sonicaps making things too bright along with those Ti diaphragms.  Those two teamed up could make for a really bright high end.

@JerrysMiddleFinger, a little late to the party, as usual, but how “easy” did the Ti diaphragms go in ?

 

I read the caveats about them and still managed to snap the “tinsel” leads on one of the diaphragms I swapped years ago. Any flexing, or forcing of the assembly is a recipe for disaster.

 

Do you have a multimeter you could check them with ?

I’ve installed a set and they were pretty easy with a steady(ish) hand.

Were you able to hear the Heresys in its original state before you made all the changes? Did it "actually" sound good or was there a significant lack of sound? I am not sure if you understand the post of Deang. He makes repairs of such xovers and other stuff and is the approved Klipsch vintage speaker/xover restorer.

They sounded muffled and distant.  Like there was a blanket laid over the speaker is the best way I can describe it.  I had replaced the diaphragms before I did the crossover and used them for a week or so like that very happy with how they sounded.  There’s no way new caps did this without there being something wrong.

Thanks.  I have no experience or training other than basic soldering and a vague understanding of how speakers work so I was half expecting to screw something up to begin with.  It was a learning experience if nothing else.  Good practice soldering in extraordinarily difficult spaces.

The diaphragms went in very easily and didn’t have to force anything.  I ran the speakers with them in for a week or so before the crossover work so it’s not that.

I can't define ironic but I know it when I see it.

You did yourself no favor going to titanium tweeters.  Change them back.  Did they come with polyfil?  I didn't think so, take it out.  If the cabinet wasn't sized for it, that causes ripples in the bass response.  The Dynamat on the plastic horns will not hurt, but may not have helped since the horns are short and plastic has far less tendency to ring than metal. 

 

No good way to troubleshoot from a distance, but muffled may indicate the squawker filter is feeding the tweeter.
