  1. Congratulations Bruce, now to locate the rest of the 1900 system. Best of luck to you.
  2. Duratex works great without a textured roller as well for a smoother finish. A little water mixed in using a Purdy microfiber roller worked best for me if you don't like the rough finish look. Duratex dries quick enough but takes a week to cure for shipping, keep this in mind after finishing the project.
  3. Last but not least you can drill out the stripped hole and glue in a dowel rod and re drill a new hole for the screw.
  4. Sound changes with the design. The K-33 sounds different in every model Klipsch makes (Cornwall, La Scala & Klipschorn) You want to match or better your sub to the mains for a seamless crossover, horn loaded sub with horn loaded mains or even direct radiating mains match great with horn loaded subs. If you find yourself turning off the sub to make things sound right you are either using the wrong subwoofer or don't have it dialed in correctly. If you never used a proper sub you don't know what you are missing.
  5. Remove the driver and mark the wires and terminals if there are no markings or note where they go if marked. Glue some toothpick pieces flush with the motorboard or slightly recessed with wood glue. Insert the old screws 3/4 of the way in and let dry 24 hours. Remove the screws, install the driver and reinstall the screws. Check the driver gasket in the process and be sure its in good shape.
  6. Its not just the length that determines the tuning frequency but it plays a part. Taper rate, throat area, and mouth area makes a difference as well as boundaries at the exit. For instance the THT and Table Tuba are the same length but act very differently or the wider the cabinet the more efficient the bottom end. You get the idea...
  7. If bigger is better why only 8 gauge wire, don't be cheap and settle for that thin stuff. 0 Gauge all the way.
  8. Witch Altec horn & driver combo are you using ? Building a new set of bass bins for 10 or 15 Hz sounds like a complete waste of time considering with less time and money you could build a proper horn loaded subwoofer to add to the current La Scala bass bins. Getting things done right the first time will pay off in the long run.
  9. I just cut a piece of scrap ply one inch larger than the existing hole in the back of the cabinet. Drilled very small holes around the piece and into the cabinet evenly like i was making a hatch cover, removed the piece and drilled out the holes so the screws slipped in easily. Be sure to mark each piece and each cabinet to tell witch goes with witch and witch end is up so you don't mismatch lined up holes. Ran speaker gasket tape around to seal. Installed a terminal cup & wire up being sure to use the most expensive wire i could find. Washers on the screws, install and snug.
  10. Guitar Violin Any solid structure Lots more if you google. If you have evidence to the contrary post it, happy to look.
  11. Just about any solid structure containing containing a volume of air with an opening that amplifies a frequency can be considered a Helmholtz resonator. For instance a violin or guitar has no source of sound inside the body but is considered a Helmholtz resonator.
  12. No need to replace the K-400 or K-401 horn, just cross it over at a lower frequency. The LSII is crossed over @ 4000 Hz and the Crites A-4500 @ 4500 Hz for reference.
  13. Cross the K-400/K-55 over at a lower frequency to reduce much of that harshness you are speaking of. The K-77 will need to be replaced for this modification.
  14. It eliminates the top section acting as a Helmholtz resonator. Notice the back on the La Scala II ?
  15. Sound waves don't change over time, the article is still relevant.
  16. Move the subs where they work best, not look pretty. Looking at the setup tells me you did not do a subwoofer crawl to integrate those into the room properly.
  17. Sounds like a bad amplifier. Any other systems to hook the sub to for testing to see if the issue follows ?
  18. Looks like a custom knockoff to me. Veneer would be very difficult inside the bass bin, its probably best to disassemble and veneer the panels that way or build new ones with pre-veneered plywood sheets.
  19. Crispy fries dipped in a Wendy's frosty is the way to go. Sounds gross but it works.
  20. Using feet, not likely. Attaching the bass bin to the top section as an alternative, could be.
  21. Save some cash and get the Dayton UMM-6
