    And if you have any extra, you can use it to Jump Start a Diesel Locomotive! bs alerts notwithstanding.

    Yes, I do understand. It's quite normal to decry thicker cables giving a little more current and sonic improvement to a speaker. It's also quite normal for the DIY crowd to find out that it's quite true, and definitely worth the time to try it.

    Hello all, 

    this is my first post to the forum. 
     

    I recently acquired my first set of quality stereo speakers … in an unusual form factor:

    klipsch heresy wedge monitors , HIE crossovers. All original. 

    3743 and 3745

    k-42-EV

    k-55-M

    k-77-M

     

    I got them for a deal , one works great… the other worked great for a moment… 

    it started cutting out at lower volumes , and distorting at higher . 
    At first I thought it could be failing caps , but I’ve read some good feedback on removing the zener diodes from circuit. I’ll be trying that today unless I am advised not to here . 
     

    i am so eager to get these going , I’m sure the information is out there but I thought I’d make this post and see if one of you more knowledgeable people could point me in the right direction and get this going faster than I could researching between jobs. 
     

    if I could retain the original caps by removing the zener diodes from circuit that would be ideal. If not I’ll probably recap both speakers and sell the original caps that test in spec. Yes I know it will eventually need to be recapped but they are expensive , especially for the HIE one. 
     

    additionally - I want to use these for home stereo use mostly, so the boxes should go. Yes it is sad separating these drivers from their original cases … but to any of the offended I’ll say this : there’s nothing more fitting for these than an act of heresy. 

    i am 24 and pretty tight w money so I’ll probably use a cheaper wood just to get them going and rehaul the project again in later years . 

    i see some talk about converting HIE crossovers to AA style . If anyone could speak to the advantages of this - it is unclear to me as of now. I can’t have opinions about what style I prefer since I haven’t heard them. And I am still learning about what a “super heresy” is. Since I’ll be building new boxes for these , anything is possible . I’ll definitely need to implement some more low end eventually , whether that be the traditional separate sub, port, or something more innovative. 
     

    I’ll be selling the wedge monitor boxes , if I could do this to fund the materials for building new boxes that would be great… I don’t have much room for storage . If anyone wanted to give any thoughts of what the boxes are worth , or the speakers as a whole , I can’t find much price references within recent years . Inflation moves fast these days . 
     

    anyways , I’m normally hesitant to jump into forums but this one seems great from what I’ve seen . Excited to be here hope you have a great day.

    Your project will definitely be fun. I started with a vintage Heresy pair, then Chorus IIs, and now vintage La Scalas. Learning is fun.

  3. I use the latest Firestick to my Sony TV, then the Sony TV optical output to my DAC. I've tried two popular streamers and bypassed my TV, but the audio from the Sony optical out is still the best. All ethernet connected.

    After hours of listening to my treated speaker, I decided to mod (i.e., damp or dampen) its partner and apply DSP afterward. My personal and subjective verdict is that I hear no difference between the treated vs. untreated tweeter or bass drivers. However, there is a noticeable difference with the mid-horns, especially when I play music that spans its entire frequency range.  As one who owns and plays various instruments from the baroque era, the Heresy twins are now projecting the same tonal quality, timbre, and 3D imaging that I find when playing the exact same "real life" instruments (i.e., alto and soprano blockflutes, 4xchoir 2-manual concert harpsichord, and 1xchoir virginal) that reside in the same room. Very impressive, especially when coupled with my KEF KF92, but it only makes me wonder what magic lurks behind Klipsch's larger brethren within the same heritage line, or how much more my Heresy twins will shine if I relocate them to my great room with hardwood floors.

    I came to the same conclusion. I updated my Heresy I pair with Dynamat on the mid horn only. It worked just as well with my vintage Chorus and La Scala speakers.

    I'm also a musician, and changing speaker wires is just second nature to me. Better copper interior wiring definitely made a sonic improvement in my vintage Klipsch speakers. If you can, make a few measurements with upgraded wiring.

    I have a set from the 80's.  Bought them for a song...someone needed new warehouse space for their stadium equipment and asked for $400 for the pair.  :) 

     

    I noticed that the new ones seem to have a spacer between top and bottom cabinets.   Does this help?   Should I be looking at this and what the heck are the made of?   

     

    Also I see stands that people make on eBay...projecting them up and getting the older ones off the floor.   Any mods I should be thinking of.   BTW - they sound great for what I listen to - I love the jazz club vibe.

     

    Anything I should do to upgrade - but not going nuts here.   Musician but only casual audiophile...living on budget.

     

     

     

    I bought a beater pair of La Scalas to experiment on a couple of years ago. I really learned a lot. The forum made it easy to document:

    Yes, self confessed.

     

    Double coat of KILMAT 80 mil.

     

    Pretty blown away by the difference.  Theorize the mass added greatly altered the resonance of the unflanged horn.

    That makes sense. I removed the Kilmat from my La Scala horns, and stuck on Dynamat, because it was thicker. The sound definitely improved. Voices, horns and drums became far more distinct and refined.

    These pictures are from a sold ad from California that someone copied and tried to run a scam.Same thing happened yesterday with a pair of ads l2030’s that sold last week.

    Yep. The ebay ad doesn't even show up in my ebay history. It was a pretty elaborate scam. They had lots of inventory from an antique ebay store with lots of past transactions, all fake.
