So, as promised, I have put these speakers into an open baffle cabinet
I have never tried anything like this so I had totally no expectations - I knew that bass will suffer but more on that later
This is the 'cabinet'
Let's see the measurements!
(at MLP, approx. 250cm away from the speakers)
Left channel only, from 80Hz
As expected, not much down there.....
L+R, from 40Hz
20-25dB would need to be compensated with EQ
Let's see that in action, with the sub added from 80Hz:
Actually pretty good, but.....:
Distortion gets pretty high around 100Hz - gets a bit better with Dirac on (green curve) but still high
I can totally hear it when doing the sweeps but to be honest I don't think I can hear it with music....
IR got a bit worse due to reflections but still not too bad in my opinion:
Blue is with closed cabinet, pink is open baffle
What is really interesting is that GD became much much better (OB highlighted)
Subjectively:
I have to say I really love the sound - it is open, airy and the stage/instrument placement is definitely not worse vs. with the sealed cabinets (I was worried that due to the reflections that would be worse but that is not the case)
The only drawback that I
think I hear is that the low-mids/upper bass lacks a
bit of energy (despite boosting it with EQ)

Next step in probably a few weeks' time is to build the OB boxes into bass reflex cabinets tuned to Fs - stay tuned! (pun intended)
