Hello everyone. Thomas, I have a question regarding your design for decoupling a soffit front wall from the framing which supports a soffit mounted speaker. I don't have the pic to refer to, so I will just ask the question.

Back in the 60', Fender produced a guitar amp called the Showman, which had a very unique baffle. There was a front baffle, and another panel about 2" behind it. A JBL was mounted in a steel forged ring, which was the size of the speaker, and mounted through a hole the on the secondary panel. The speaker was fastened inside the ring, to a flange which, when assembled, extended through what would be the speaker hole in the baffle. However, the hole in the baffle was 1" larger in diameter than the ring. This created a gap, between the ring and the baffle, whereby the speaker did not touch the baffle.
Is this the same thing as your design, where the speaker box, does not touch the face of the soffit
wall but has a gap between the soffit face and the speaker box? Would a design for a soffit face work, with something similar to the Fender design, where this ring actually extended foward through the soffit face? Hard to explain, but maybe, if this is not clear, I can upload a section drawing. Its a convoluted affair for me, as I use Autocad, which isn't supported here as you know. Anyway, thats the question.

Rick, I think what you described may be more of a "bass reflex" cabinet design, not sure without a pic.

Speaking of which, I'm going to see if Peter will enable DWF for the site - then you can go direct, with file size limits probably around 150k as they are now.

Other than that, if there's a Staples near you and you can spare about $40, go there and buy a copy of PDF Producer, by a company called Data Becker. I use it - it installs as a "printer", so ANY application that you can print from can now become a PDF file. You can set the resolution wherever you want, from about 75 DPI up to at least 600, maybe 1200. (Higher res ups the file size, so there's a limit - still, it's much better than "bitch maps"... Steve

Hello Steve. When I save an Autocad file, it saves in a .dwg format. What is the difference between it and .dwf? That question has been on the list for a LONG time. It just keeps getting longer, ..and longer........and longer............hey, what was my question?...oh yea..

Lost most of my answer, freakin' senile old farts with computers, bah humbug...

Load a drawing into your version of Autocad, then click "save as" , and see if one of the options is DWF - stands for Drawing Web Format. Their cheapie QuickCad does it, and I got the impression it's in most of their stuff now.

There's a free Viewer (no changes, and I think DWF's are NON-editable) but same res, and wheel mouse is supported for zooming - actually a great way to send illustrations. Reminds me, gotta check if Peter can enable that as file attachments...

Anyway, here's the link for download of the Viewer -

if Peter can do it, I'll post the link so peeps can go hi-res if they want... Steve

freakin' senile old farts with computers, bah humbug...

I know the feeling well. My son rolls his eyes at my feeble attempts to understand HIS computer savy. He has a gaming and ftp website that he built from scratch. He keeps telling me he can set up a whole website for just me, with everything from forums to whatever. Ha, what the hell would I do with it. I do keep my .jpg's there putting links on the recording forums. But I haven't got enough time to assmemble my console, let alone work on a website. Drawing is another thing though. I'm pretty fast at that.
At least in autocad.

Ok, about the autocad thing, do I have to attach a link to the viewer with my .dfw files? I don't understand that one either.
Talk about senile. I've got the drawing stuff down, but keeping up with computer technology is like keeping up with the firewood.
Let alone recording technology. Ok Steve, thanks for the info, again.

Rick, it's DWF, if you're using 2002 or later it's available in the "save as" file menu - and, until I find out if Peter can/will add that format as acceptable file attachements HERE, there's no point.

When I get that part done, I'll put a link here on the site (construction forum) for the viewer, so all you would need to do is attach a DWF file.

I'll post a notice when/if I pull it off... Steve

BTW, my son=same thing - only he's so busy making a living/growing his business that I've still to see any web help - Still, guess it beats having to support him myself...

Can you save it as a DXF file?? smartdraw and many other programs like paintshop pro can import DXF but not DWF and DWG files.

cheers

Hello John. Yea, I just looked. And I have paint shop pro, but after I pull the DXF into it, then what? Change them to a .jpg for posting here?

Hey John, haven't had time to play with Smart Draw yet so I didn't know it could import DXF - If you could ask Peter to enable DXF that would give us a high res format that most could not only view (limitation of DWF) but also modify - even my old Generic Cad 6.1 DOS "brontosaurus" can do DXF's both ways - that would be 'way cool.

Rick, once this gets set up you could just post DXF's direct. Probably still hafta keep 'em under 150K though... Steve

Just ran a 895K DXF thru zip manager, zipped down to 43k. Rick, you're gonna need a zip utility - holler if you don't have one... Steve
