The Slot Loaded Open Baffle Project Article By Nelson Pass
I am phantasizing about a floor to ceiling slot loaded open baffle using 10 Tymphany XXLS-300F50AL01-04 per side.
As a little exercise I experimented a bit with slot loading on my Beyma 15BR100 U-shaped open baffles.
Thight fit, but moveable with rubber mallet
Anyone done the same, what are your perceptions?
I conclude with Pass'...there is gain, also I would say "attack" and "faster". On the negative a bit of change in tone, the mellow and effortless of true open baffle has changed to a bit of "hollow" and yes...boxiness. The cool thing is how easy it is to experiment 🙂

The bass is blown towards you. 🙂 I don't know if that's a good idea or not? I wonder if the perceived "punch" is due to the temporary pressurisation of the room similar to a sealed speaker.......perhaps this causes the transients to sound better, are there any measurements?
Let me tell you what I have that maybe could be employed for measurements:
Behringer DEQ2496
Dbx Venu 360
T.bone MM1 measurment microphone
Yorkville power mixer (phantom voltage supply for MM1)
several laptops
raspberry Pi model 3B+
So I could send a certain spectrum via laptop/pi to the system and pick up with the MM1, either with the RTA on the loudspeaker management systems or resample the analogue back. Any guidance on open source software or simple gear is appreciated,
cheers

It would be nice to see some measurements, if there is correlation between the sound and the response.
Slot loading effectively increases cone mass, which reduces fs and increases Qts. Sensitivity is also decreased. Air volume between cone and slot should be as small as possible, to avoid screwing up the frequency response at higher frequencies (say above 300 Hz for a 15" woofer).
Dipole spacing might also slightly increase but I am not sure. If so, it would slightly increase sensitivity.
