OK.  Here is a sneak peak.  Won't give all the details just yet.  Tractrix bass horn.  For starters..dual K31's.

JC, you missed your calling!  When are they getting fired up?

jc!  What's the design's fc?

Obviously the guy has a problem and can't stop building horns.  Not sure how to help.  I wish I could stop eating so much. 

Hi jc,

I thought your bride forbade you from playing with the saw.

Nice work!!  It appears the two horns are NOT identical.  There seems to be an additional vertical member in one of the horns.  What is that?

Did you just say "vertical member"?

They are the same.  Those are temporary vertical braces to keep things stable during the placement of sidewalls.

 I've seen those in person. Nice big horns : )

Very cool.

What was the design intent this time?

A while back I built a test straight bass horn.  Shown here on the forum.  I really loved the sound.

So I wanted to build (the best I can) a no compromise straight bass horn that would fit through a single door.  Well to build a straight bass horn that will go down to 40Hz won't fit throught the door as you know.  This horn shown here won't fit through the door completely assembled.  The woofers and back chambered would be added after placed in the house.  Now if you have double doors...no biggie.  heavy booger....1" MDF sidewalls.

I wanted tractix....so I chose this design.  I'm hoping to get about 80Hz-600Hz or further with K31's.  This horn is "full space".  In my corners I may go lower too.

You know I was messing with the idea of 8 lab 12's to match this thing as stereo subs.  Not sure if gonna build or not.

If I have the time...will come up with a big midhorn to go on this bass horn.  Not sure about that either.

Yes Bill...my wife booted a lot of my play with building and "big".  She actually has been trying to sway away from horns in general.....tired of the looks.   So these bass horns may never make it into my house.  May test with K31's and some other woofers I have in mind.  Then they may be off to my storage unit to join much other lonely big horns.

For the last month, I haven't even heard a horn.  My LS II's haven't had any play since Seti was here 1 month ago.   My K402's are face down on the floor waiting for the Dtels to come pick them up.  The big black holes had to go.  I could have put them in storage with my TAD 4002's...but that just wasn't right....somebody needed them....so unloaded.

Oh, no, jc, that means . . . . .direct radiators!!  OK, what did you do????

Condolences, my friend.  

Hmm....well...it ain't what I did.  My wife did.....I'm not making this up.

I don't mind showing these photos here as it should be obvious I love horns...

I see "Bose" in your future if this keeps up!
