I've made some progress finally. Should be done 100% in a month or so. I'm trying to think of a good name for it. Any suggestions?

That's a good lookin' horn. I've had trouble finding a name for the drivers too. Started with MAG12 and then Eminence wanted to make sure it wasn't confused with their Magnum 12. Danley suggested LAB12 ST and that would be great, but Eminence was afraid it would be confused with their LAB12. So I just about decided to call it the woofer formally known as Prince. But I think I'll call 'em B12 subwoofers instead. I've got a name for you. How 'bout T-Rexx? That sounds cool. Somebody already has Leviathan, but I liked that name too.

Mike,
Afaik, it's the same lab's that Tom D. designed but he has it in an arrangement that the subs are shoot towards the middle, rather than in a corner loading scheme. From his other renderings he's going to put 3 TD-1's on top for a LCR configuration for HT. It should kick some ass without putting cracks in the dry wall. :)Bill W.

Hi WayneI believe this is the fruition of a project on the lab sub forum. Here is a recent post on the sub forum. http://www.prosoundweb.com/community/read.php?board=3&id=153898 In which case it is a pair of Labsub / BT-7 shaped horns with a flare extension.
This should be capable of being quite scary when finished. I don't know if you have built a proper horn with the LAB 12 yet but they are quite powerful, more so than one might expect even. I have some measurements from Eminence on the shorted turn (flux stabilized in marketing speak) driver.
I will go through them tonight and let you know how they look.
I should have the real thing in hand shortly.
Got to run, Tom http://www.prosoundweb.com/community/read.php?board=3&id=153898

I have modified the LABsub design to perform as Wayne describes. It is still very much an implemention of Tom Danley's concept and very close to the original. In some ways it is closer to the design Tom published than the original LABsub (rear chamber volume for example). When I first saw the LAB12 driver my inpression was "this cone looks indestructable", so a higher compression ratio closer to the BT-7 should be OK (higher HF cutoff). Then I added a mouth extension so 2 of them would work OK in 1/4 space (lower LF cutoff was achieved).
