Tekton Brisance

20 hz to 350 hz. Has a pair of MB couplers? That is a lot of room to blend a bass bin.. Use to be hard to find one that would go that high.

Those numbers (20-350) were used to blend Soundlab or Quads.
speakers. Usually a 12", can go as high as 800 hz or so before they really start ringing. Looks like 6.5 or something? Probably go even higher.

Looks like it has separate tuning ports for them also... Sure a honker on top.. Facing forward, though, I don’t understand. Back, down, side or up, but not forward... I guess you could get it to work better, closer to a wall?

I just saw they have columns, 4-10. 45.5 inches tall. They will Stack And Test, SAT at 91 inches. Got me thinking... He'd probably cut just the baffle. The only cut, if you screw it up, you start over.
More holes, more sweating, more chance of a screw up, and a
Start over.. ;-) I'm getting old, no do overs...

 Who makes the drivers? Anybody know? No mention of driver manufacture?

The Brisance 18" is a PA driver. @ 100 db sensitivity, it looks like a 
PA driver..I've used LARGE PA in nearfield. HT.  A lot of bang for the buck. Problem back then was floor noise. Class d normally have ZERO, no noise.. We didn't have class ds, PAs could buzz a bit.. Me I don't watch TV or use HT, 1/2 hour news once a week, all I can take..

DBA has been around a LONG time. We just didn't have cool running high horsepower class d amps. I had 4 bass bins and two Horn bins in the early 70s, All the boxes were ran on 30-40 watts amps, Macs..
Used them at school dances from time to time..2 MC240 and a pair of 30
220-240 watts. The place was rockin... oh yea..

The last 10 years, BASS amps have really became reasonable, with ALL the DSP goodies. 

4 12K Behringers NEW, and a 2496, will do two square blocks of BOOB BOOB under 2500.00 that's a lot of watts, and a lot of control.

8 3000s,16 1500 watters, PA, or HiFi. !40-50 DB....
You could double it again 32, 15" 1000 watt drivers..

Lets talk low dollar low distortion, cool running.. BASS...
Gatling gun BASS... Yup that's what I call it...Old hat...Old news

BUT Columns.... that's something the Greek, and Roman could agree on.
I guess Irish too (ME)... I'm gonna contact the guy, on baffles and who make the darn drivers... I bet I won't be surprised. Good wire inside goes a long ways too...I wonder what is being used?
