need a visual model for CAL's

Thanks, audioassassin, that is exactly what I need to see! Nice snow -- looks like you'll be having a real White Christmas.

OBI, thank you for the options. We have a good lumberyard relatively close by that I'll have to visit. I'll take a look at that plywood you suggested.

Russian plywood isn't something that most lumberyards stock unless they deal with furnituremakers or craftsmen who use it for high end built-ins and such. I'll take an edge picture to show you what the effect looks like.

I just called my local lumber company. The salesperson said they carry "Baltic Birch" which is a plywood. It's a 1/2 inch, 5' x 5' sheet for $42.43. She couldn't tell me anything else about it though. Before I run out there, does this sound right? It's only a half inch thick though.

Yup! Same stuff, but the inch and inch and a half thick stuff is usually special order unless your lumberyard specializes in hardwoods, veneers and other woodworker's woods instead of general construction materials. I am fortunate to have 3 such lumberyards in close proximity to me (the advantage of living in a large city with lots of craftsmen). If you can only get the half inch stuff, you can easily glue and press 2 together to get 1 inch thick stock. Can anyone measure the overall thickness of the Amazing's panels?

-1"

Thanks maxxx, now can I bother you for the other measurements please? Hight width at both the top and bottom? I'd like to see if I can find a way to get the correct size here to make proper 1 inch thick panels.

-silvers= 54"tall

-27.5"at base
-22.5"across top

-trapazoid

-1"

OBI-san...are you up to what im thinking your up to .
if in your hunt you can rustle up an extra 30" ribbon for your friend the assassin id be very much in your debt.

Thanks again maxxx. I'm not sure what you think I'm up to, but I'm just trying to find a way to help out an-eagalach with getting his panels the correct size by knowing what size lumber he will need. Can't swear to it, but I think he needs the size for Plats or Originals.

Now, what is AA77 up to that I should know about???

Marc .....

Hi Obi, Maxx is right on (as usual) in the measurements of the silvers, He being the "silver king".

I thought I should add that the inside edge is straight. That is the side that houses the ribbon is 90' top & bottom. The outer edge (woofers) slants inward bottom to top. Just in case.

Frank.

late reply again .
Mr.OBI-san. judging from your posts in this thread id almost become convinced that you were also looking at "rolling yer own" AMAZINGS(or a smaller version of same).
i could be mistaken of course(not the first time).

LOL@AA77!!! Interesting idea, but why would I want to roll my own when I have still to hear what they sound like and if I would even like them? + I'd be looking at building AL-III clones before Silvers or Plats due to the size issue.

Hmmmm, just got a weird idea .... Wonder if I could source a pair of 30" ribbons and build some mini AL-IIIs (AL-1.875s?) no crossovers but fully bi-amped ...............

funny.
id thought you were thinking along the lines of scaled down amazings.
same trapazoid shape 1/2 size would be mighty interesting.
active cross, 2 12" drivers per with a single 30" ribbon.

if you were to use the aforementioned butchers block id bet you could come up with some nice small drafts.

Actually, with 30" ribbons, they'd be AL-1.6s, because AL-3s have 48" ribbons. The real problem is getting 6¼" woofers. Still be cool, though. They'd be about 45" high. The woofer box would be about 14 3/8" high.

Correct as usual BillD. I remember thinking they would be 1.6's but when I ran the figures through my calculator I came up with 1.875 for some reason (probably something having to do with an extra inch somewhere). I knew it sounded wrong, but hey, I'd been out shoveling all evening and was warming up with a hot Irish coffee, so ......

I'd still want to use 10' subs for an AL-III type speaker IF I were to build one, but AA77's idea of Mini Plats with 2 woofers is intriguing. The acoustics alone of a 2 woofer trapezoidal setup would be devilishly complicated to figure out.
