Anthony,
Yes, this is the exact configuration that I have. As you drive your LF channels down, probably it will be 30-35Hz with >2 order filter you will like the sound from them even more. I hope you have a good amp to drive is as Milq will not have enough gain and power. Grabbing any brutal SS amp will not work in my estimation as they produce too dry and too fast bass. This is a very separate and frankly a complex subject how to drive the lower bass to compliment your DSET.
The Vitavox 15" drivers. It should be time-aligned and should not be “good”. Do not invest a lot on into the enclosure and it is most likely you would need one driver per channel not 2. The Vitavox 15" drivers are in my estimation are stanning as direct radiators, the best bass I even heard in my life came from them. To use them in context of your installation is relatively complex as your midbass will be working in relatively narrow bandwidth and will literally fill some gaps. It is not practical to talk about this type of midbass in terms of frequency and it will be rather an “cloud” of sound that will be to great degree contingent upon your specific sonic signature of R and L channels in your specific listening room. Do not waste a lot of money for enclosure sand do not be afraid to go asymmetrical with you narrow band midbass: this is advantage not a drawback. Yes, DO NOT get seduced to subtract sound running it in back phase to your room problematic zones. The neighboring channels MUST sumazes not subtract, even if subtract fives to you flatter response.
Get from eBay for $50 a pair of sealed car’s cubes, I think they are 20X20, put in there some foam and it is all you need. You can start with one channel and you two driver per side It will take for you a week to fine what you need of you have a stock of coils and caps home. They it will take for you another 2 weeks or so to find peace with the volume of the that midbass. That midbass will be very beautiful and you will be impressed initially but with time goes by you will realize that you do not wans to be impressed by the bass and you will find a way to subdue that impressed and to let it to shoe own only when it needed. It will take bot you a few years to fine a good power amp to drive your lower bass section. Let me know what you will end up with as I do not have prices with what I have.
Yes, one more thing, if you wiling to drive your new midbass from Milq’s lower Chenal then do not forget the proper loading. You bass tower probably are low on R and your Vitavox is 15R. You might need a another OPT or remap your sections of you can. Generally, the more you ideal the amp against this driver the best I find the result it, like use 2 or 4R output taps. You will be losing power with that starvation loading but you most like will like the sound.
