  1. yikes, are the tweeters still tweeting ?
  2. @Jeff Matthews, everything changes when you change anything, whatever balance you have now will be different if you take a different path. Whether you like the change or not is entirely your business. Different is fun too, but the engineers had a plan. It looks to me like you have type A crossovers in there right now. I am going to ASSUME the tweeters are the round magnet Alnico version and the K-55 is the single phase plug version as well. The type of drivers in your speakers are an important consideration when choosing a path. There are limits both in frequency response and power handling depending on what drivers you choose to use. If you like the way they sound now, new polyesters will preserve that presentation. Probably make it a little clearer considering the age of those capacitors in there now. @jjptkd’s idea about trying different caps is a great idea. With a little effort and a very small outlay you can be sure which path you prefer. I really enjoyed a pair of Crites A/4500 crossovers I had recapped with polyesters in a pair of LSIs (before Crites offered a copper version), albeit with aftermarket tweeters. When pushed a little harder they held it together better, but at low to moderate levels, the “bright” Sonicaps were more revealing. Your ASSUMED alnico tweeters won’t appreciate being pushed hard, so that is a serious consideration, replacements for them are not falling off trucks. IF I understand the driver complement in your Khorns correctly, I would expect the type A crossover using a K-55 that rolls off at 4500hz to sound very similar to what I was using.
  3. @Kopek, Klipsch had a couple of sleepers I didn’t know about until I found this forum. A little taller and about the same size as the Forte’s footprint, but only in black, the Tangent 4000, and especially 5000 are outstanding performers.
  4. @susan, the crossover and midrange driver might help narrow down the year a little closer if you can get a picture of them
  5. @Deang In the decade or so I’ve been following this forum you have always been the catalyst for progress and knowledge. Sometimes at the expense of a few battle scars, but always emerging as a rational voice. I would just like to take this opportunity to thank you for your DECADES of positive contributions. None of these forums would be the same without you.
  6. …which Heresys, 1, 2, 3, or IV?
  7. Yes! What a difference three years does make. Looking back at this thread after finally building a pair of ALK clones, or five to be exact… That 33uF cap in the CSW 450s is/was not doing your La Scalas any favours, anyone’s for that matter. That is the value for a 600 Hz (roughly) cross, a 47uF cap will make the La Scalas come alive. No wonder you preferred the Volti VTK 400s, amongst other reasons. I would bet the Volti has two 24s paralleled for 48uF.
  8. …long ago, before the dark ages, one could read of the exploits of the common man in his pursuit and passion for a peaceful pastime
  9. @Delicious2, if all else fails P-Audio makes a copy of that tweeter. I THINK you can get a pair of them off eBay for $50. Whatever the sonic differences are will match.
  10. …ran out of gigabytes here’s what they look like standing
  11. Hi @jjptkd, yes the 396s use the same foam, and probably the same spacers on each screw holding on the grille. Hope you had your speakers laying down when you pulled the grille off, lol. Just this week I finally got around to cobbling a make-shift pair of stands. I think I paid about $50 CDN for the hardware at Home Depot, what a time to be alive, lol. CAVEAT ! They are little front heavy, if bumped from behind or pulled from the front past about 10 degrees they are going to tip forward. I just wanted something to get the bottoms off the floor to keep them from getting scratched and at the same time raise the horns to ear level, I’m 6’5” and the 6” of lift on these speakers is perfect.
