Modified CBT24

I dont really wish to put them on the sides of the arrays due to the windows in my listening room :)

Oh, that makes sense. In that case, just stick them behind. You probably won't go very low with those so your enclosures won't be large. You could design them to compliment your curved CBTs. If you want lower and larger subs place them somewhere else because it won't matter.
 
A year of listening later I have finally begun doing some audio related projects again.


My goal is to get a pair of subs to complement the CBT24s, so first thing was to figure out how to connect everything.



So as step 1 I got myself a MiniDSP nanoDIGI 2x8 to serve as an active crossover (and for room correction). I also got an UMIK-1 so I don't need to tune blindly.



Oh boy what a difference some equalizing did. I was happy with the sound before, but after doing a first measurement and letting REW create a filter to flatten the response I am now floored!


Next up is ordering the subs (SB Acoustics SW26-some version).


Here is the frequency vs spl graph I measured for my first try using REW (1/6 smoothing applied).
