  1. 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.
  2. 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.
  3. Guitar Violin Any solid structure Lots more if you google. If you have evidence to the contrary post it, happy to look.
  4. 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.
  5. 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.
  6. 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.
  7. It eliminates the top section acting as a Helmholtz resonator. Notice the back on the La Scala II ?
  8. Sound waves don't change over time, the article is still relevant.
  9. 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.
  10. Sounds like a bad amplifier. Any other systems to hook the sub to for testing to see if the issue follows ?
  11. 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.
  12. Crispy fries dipped in a Wendy's frosty is the way to go. Sounds gross but it works.
  13. Using feet, not likely. Attaching the bass bin to the top section as an alternative, could be.
  14. I doubt flipping the bass bin 90 degrees will do anything but experimentation is free. Install braces.
  15. Many here have probably heard them in the past and just didn't realize it.
  16. The Altec Lansing "Voice of the theater" models A1-A8 was used since the 1940's and still in many theaters and homes today. I can't see how these did not make the list. Dam good sounding speakers too.
  17. If you really need more bass and want to keep the La Scala's i suggest using your money on a parametric equalizer (PEQ), porting the cabinet will also help.
  18. Wish i had better news for you. I have done much testing with many models (big, small & multiples of them) and have come to the conclusion i recommended to you and others. Save your $$$ and do it right the first time.
  19. If you need a sub for La Scala's get a horn loaded sub. None of the subs mentioned here will do them justice.
  20. The kit mentioned earlier or the Ultimax 15" kit ? The 15" Ultimax kit is fine. The HO kit if you could substitute the HF series driver is OK. I'm just not a fan of sealed subs unless you have a bunch of them.
