  1. Beautiful Sent from my SPH-L720T using Tapatalk
  2. Found my notes. Going to the ported mod resulted in 3/16 of an inch setback to the rear. Sent from my SPH-L720T using Tapatalk
  3. But it wasn't much quarter to a half an inch or something like that Sent from my SPH-L720T using Tapatalk
  4. Port mod does cause additional group delay. Had to revise the shift after port modding in my system. Can't remember the exact amount. Sent from my SPH-L720T using Tapatalk
  5. Ditto Sent from my SPH-L720T using Tapatalk
  6. My voice coil plate front surface is approximately 14 inches back from the bass bin rear surface. 12 DB crossover slopes. Sent from my SPH-L720T using Tapatalk
  7. Mine measured good down to there. With baffle, use 15 and three quarters inches. Sent from my SPH-L720T using Tapatalk
  8. When I was using the K400 the setback I was getting was 16 and a half inches from the front edge of the cabinet to the front edge of the unbaffled K400. That might be a good starting point also want to get it a few inches up off the deck Sent from my SPH-L720T using Tapatalk
  9. Now begs the question , which has the better bass?. The better lower mid-range blend to the mid-range horn? Sent from my SPH-L720T using Tapatalk
  10. La Scala , too. The older lascalas have the big splitter. Reduced in size in the later models. May have something to do with the TS parameters of the later k 33 changing. Sent from my SPH-L720T using Tapatalk
  11. Horns are Klipsch. Cabinets not Sent from my SPH-L720T using Tapatalk
  12. Have you verified there IS a resonance in the motorboard? I don't think mine do. As to the splitter, it it the beginning of the horn and the expansion rate is important there, so I'd calculate carefully the impact of change you are proposing. No I'm not proposing a change these are the way they came stock. The splitter, that is. I'm very satisfied with its performance. Mine's an older model , with doghouse hatch under the mid-range horn. That's why my Splitter"s the larger one, I imagine. Thanks guys for your input!Sent from my SPH-L720T using Tapatalk
  13. I think one could put in a couple of pieces of 1/2 inch ply between the baffle and the back with some PL Premiums and accomplish the same thing. Won't be hard for me to do this on my as I do the refurb... Bruce The plywood pieces would help somewhat and I think you'll like the difference. The good thing about the lags is that you can tension them like truss Rod's and it seems to reduce the resonance the mostSent from my SPH-L720T using Tapatalk
  14. My big splitter is like a two-by-four cut diagonally, using both pieces. The smaller version is like a 2 by 2 cut diagonally, using one piece placed flat. Sent from my SPH-L720T using Tapatalk
  15. http://cloud.tapatalk.com/s/578994d7e3375/20160715_185733.jpghttp://cloud.tapatalk.com/s/578994e986fa3/20160715_184758.png? Here's the label on the back very old but still readable. The serial number is 2m449. Sorry about the error. As you can see in the photo it has the big splitter. Perhaps because it does have the Paducah CTS driver that's what they went with in 1974. That amounts to a tighter throat squeeze perhaps they subsequently decided against that. As for the lag screws, I decided to to do that modification myself. The two half Moons formed by the woofer periphery and slot seem to have quite a bit of resonance in the upper range of the woofer. By running those shafts back to the rear panel and lightly torquing down I was able to move that resonance up in frequency of the woofers range resulting in quite a bit of improved clarity in the 300 to 400 hz region. I did this in about 1980 as one of my first modifications. I bought them from the original owner which I know would definitely not be one to fiddle with the throat structure. Any thoughts? Sent from my SPH-L720T using Tapatalk Someone asked about the slot dimensions. It is 3 by 13 inches. The mid-range K400 horn also has a casting date of August 1974.Sent from my SPH-L720T using Tapatalk
