Hello there,
I had a strange idea at looking the spec of the Peereless SLS-12, used in the famous Jazzman ripole.
Here is the TS spec measured by a Dibirama website . Qts : 0.52 ; Fs :30 Hz , Xmax : 8 mm ; sensivity higher than the datasheet with 91.5/2.83V.
The PA Faital 12PR320, a more a pro midwoofer than a woofer, falls faster than the SL-12 below 100 hz.
It has 93dB/2.83V at 100 Hz, 2 dB more than the Peereless here; 85 dB at 50 Hz (IEC Baffle) only but it is what showing also the peereless SLS-12 datasheet.
The ripoles circa extend the Fs by -10 Hz and drops the sensivity by 10 to 11 dB. The Faital has 42 Hz Fs. In ripole it means around 32 Hz
Xmax between the two drivers being quite equal, minus the worse Qts of the Faital 12PR320 : 0.38/0.40 in real life ; do you think it is feasible to use two Faitals 12PR320 for a Jazmann's ripole if two Sub in the room ? The EBP of the 12PR320 is 100, twice than the Peereless, so theorically more made for vented.
Thanks
Edit, is there a way to sim that. I only know Vtuix Cad, not an easy task but playing with the baffle step option to reduce the baffle at the size of the driver and click to x2 driver and seewhat the baffle step loss could be as an open baffle (I get -11 dB at 40 hz...) but the only OB sim I have is with an infinite baffle (I assume IEC baffle dimension for Vituix compute)
