Use something other than image shack to host, they suck...
An externally hosted image should be here but it was not working when we last tested it.
I picked up a pair of these. I want to implement the design presented by bjorno in post 46. I am a horsrep newbie....but I'm trying. Before I spend more time does this look to be where I should be going. If so I can fine tune and post with measurements...If not back to the drawing board.
Thanks, Evan

The Keystone goes a lot lower than the SS15, but the Lab 15 (s) would not be a very good driver for it, too peaky of a response at the bottom and top.
Bjorno's design in #46 looks quite nice for the Lab 15, but still won't keep up in output to the Keystone with proper drivers or the SS15.
Evan,
From a quick look it looks like you are on track, though a single fold would be a lot easier to build and take up less floor space.
Art
Thanks Art. I thought of a single fold, but the cabinet seemed very long or tall depending on orientation.
I am unsure about s3. If the cabinet is the width of the driver then s3 is only about 4.3" deep this is not enough room for the driver. I made the assumption that this space could be larger because of the volume taken up by the driver.
As far as complexity of build goes I'm not scared....

evan, you are a talented artist! i had to rush my project due to a limited time of production space acquisition. i also think this is the last time i will use mdf for an entire project, though the consumption of vast amounts of pleasureable mexcian beer during this recent BR has led to a most pleasant production time indeed...

Hi evanc,
Your drawing for bjorno's T-TQWT from Post #46 looks fine. This is not a tapped horn. For the T-TQWT the magnet assembly usually ends up on the S2 side, that gives you sufficient room to mount the driver from the S3 side. Bjorno suggests to double (or tripple) up on the driver mounting baffle if you need more room. You'll probably have to design-in an access panel.

Guys, thanks for the encouragement and advice.
tb46...excellent. The driver facing the outlet or s3 will send me back to the drawing board but it's nice to know I'm going in the right direction. If the driver comes in from the front the access panel could be the front of the box.
I'll work on a more refined drawing this evening after work.

Couldn't agree more. I like Picasa, not sure if Google will suckify it once they force me to switch to Google+
This time with some dimensions.
Does this look OK?
How close to the ideal does the horn really need to be? Both length and cross section.
The s1 s2 length is listed as about 5". Since this is less then half the driver dia. should the 8 3\8 floor of the horn slope up to reduce volume here?
Thanks, Evan
