Thanks Romy,
I was hoping to hear that you remain happy with your midbass solution and was surprised at the time about the small cabinets that you used for the Vitavox 15"ers, but having measured T/S parameters of the drivers here I can see that indeed they do not need much of a box at all...the cube you suggest is pretty much ideal.
At the moment I use the DSET lower channel to drive my lower bass and I have plenty of volume sub 20Hz thanks to a well sealed room and resulting high room gain. This should not change and I expect to continue running the Bass Cannons from Melqs lowest channel. The midbass channel will give me a little flexibility to play with how low the upperbass horns are cutoff because I feel that the Bass Cannons are a just a little stretched once they get close to 100Hz. When I first built them I indeed fell in love with the sound...never has bass been so soft and full and effortlessly articulated in my playback and I was lost in throngs of that passion for a long time and just could not hear your words about the sound as they approached the UB horn. Well, with many listening hours and a familiarity with my sound two things have been identified for improvement and that slight change of 'clarity' circa 100Hz is one of them along with the 40Hz room problem. A third may prove to be more flexible integration of the UB horns by passing them a little higher.
Midbass can be run from the DSET Injection Channel as I have yet to experiment with that speaker. It will be Melquiades from 10Hz to 40kHz.
At this stage the 15" can be boxed individually and hung from the side of the Bass Cannons, most likely on the outside, or even placed on top of the horn stack where your Tannoy Reds are situated. I think the former will be the better solution given the closer proximity to the UB horn and the direct sound not being blocked by the Fundamentals Horn. Hanging from the Bass Cannons also gives the flexibility to raise/lower the Vitavox drivers in increments of 30cm (12") just by changing the Cannon from which they hang, and because the Bass Cannons sit on pneumatic isolators and do not shake the floor directly (only with sound pressure it seems) the room sound proofing will remain intact.
I will give this a go.
