Ooops, I thought you were in VA for some reason...never mind.

Actually, I just got back a week ago from FLA. My parents live in Coconut Creek. Somehow I don't think I could have gotten them past the TSA, however.

tomorrow is the day i'm getting the plywood and starting. i have the layout for all the cutouts. i should have very little waste.
i have read panos thread twice and anything else i can find on the subject. what i've learned is;
1 brace the inside on any panel over one foot using the .7 ratio GM suggests.
2 deaden the horn. i'm thinking about making a composite horn flange using a hull system we use that's eaten small arms fire
3 adjust the port for better LF. possibly turning it into a horn in itself.
4 i haven't finished reading some of the old posts yet.

but tomorrow i'm starting.

I had some plans I drew up for an a7 it was made from solid plywood It would have weighed a ton and cost a fortune but I bet it wouldn't have resonated. It too had a horn for the port. everything was rounded no sharp corners.

[Phil-G]

i got almost all of my box pieces cut. all thats left are the bevels on the horn bottom plate, and the front piece that butts up against it.
i'm still leaning heavily on forming the horn flanges out of fiberglass composite. 1208 glass with divinicell coring. using vinylester resin. one things for sure. it would not give.
cradeldorf id be interested in seeing what you had in mind for the port horn. otherwise i'd like to do what GM suggested to pano and do something like an 8" tube.

[Phil-G]

maybe a little overboard but i thought it made a nice pick.

If it can be done with without looking different/odd, I'd go for it!

.......otherwise i'd like to do what GM suggested to pano and do something like an 8" tube.

I'm sure it would sound fine, but too me, the look wouldn't be right. Did GM say why he suggested it? Does it have an advantage?

I'd love to build a cabinet someday.........someday when I get everything else done that needs to be done!

you would never be able to tell once it's painted. it would be simply like a section of high performance boat hull. it would look exactly like what comes with an A7. i do a lot of custom fiberglass at work plus electroncs and mechanical systems.

phil..you started today?! you are inspired...i'm impressed. lookin' good

he did but i wouldn't have understood half of what he said to save my life. sufficed to say it would work. i don't care what it looks like as long as it works.

i have a lot of things that need to be done. but i just want to hear what these sound like.
