Default "thats kinda ugly"

Ok, so I started modeling a speaker, figured out I needed a sealed box about 1 cu ft. I used the golden ratio to determine internal box volume size, so figure + 1" on each side for wood with

Width = 12 "
Height = 19.41"
Depth = 7.4"

I chose width to be 12" so that way as I am using a 2905-9900 revelator tweeter, with the 5.11" cutout, I could attach it on the baffle which would have 1" curved baffles (if i can get it at 1") according to the golden ratio which would place the center of the tweeter at 2.3" to the right/left of center and 6" from the top and the woofer 1.5" to the right/left of center and 6" from the bottom.

When i modeled the box in BDS, my wife's thought was, "that is kinda ugly", and didnt your dad own a pair of those, referring to a pair of early 1980's JVC speakers from sears.

So my question is, is it worth it to have speakers that are kinda ugly for the sake of limited internal reflections and ugly/offset driver placement for the sake of limited baffle deflection? If so, I'll gladly build them. If it is the same as highly angled baffles and lots of internal damping then I would prefer a more eye friendly box, but, if this the ugly box is a more efficient and useful solution then I could live with the ugliness.

again, yes.

most of the boxes you will see in stores are designed with one formost purpose in mind, the looks of them, not the sound quality. Looks sell. The worst example of a loudspeakers cabinet is the small floorstanding tower speaker. these are in fact too short tl-lines with a closed end, in other words a resonating column with one strong resonating point. Mort manufactures cure this with excessive use of damping material wich could solve the problem but it also kills all of the 'energy' from a loudspeaker. Have you ever seen high quality studiomonitors designed this way. No, they are stlll of the "ugly" type and not because they don't know any better.

I assume you have your 3D visualizations? Can you post them? I have done a bunch of GR based boxes, and they ain't ugly.

Well, I just read a suggestion about baffle diffraction and there was like this:build speaker as narrow as posseble + edge to do as rounded as posseble! But here I am listening totally another tips.

But one thing I figured out, is that the distance from edge to the driver should be different for each driver (woofer, mid, tweeter). Correct?!

Finally, a Guy who doesn't need to ask His Wife - He just builds.

Why is it Men always end up in the basement or garage but we're supposed to pay the whole Mortgage?

bluto,

I always feel its easier to ask for forgiveness rather than permission. if you ask for permission, it will be "no" if you ask for forgveness it will be a "yes"
