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?

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.

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???

Trapazoid

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 #-o .
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.
:-k
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.
