I have a home-theatre to feel 20Hz, so to say.
The ratio of performance versus costs reduces quite bit in what you are suggesting. You know, from start my intention is to put least possible money to get best possible sound quality. Ripole make one step ahead in that direction for me. It is quite apt bang for buck design for me.
If you see top view, difference between Ripole and H is the pressure chamber port. And that port infact increases Fs of drivers with the loss of SPL. I am okay with it. All designs are one or the other a set of compromises.
I do not think 20 Hz of sound produced by a Tabla can be felt. But, I can feel such low frequencies coming out of kick drum. Air volume handled by the drum is quite more.
OB uses walls to create 3D image.
Actually, we both should listen together while discussing, then only it will be cleared. I know Ripole is good but you can not realize it unless you hear it. Just like the way you once were convinced that 6 to 8 inch high Xmax drivers are the best for low frequencies and I followed bigger dia paper cone drivers with quite low Xmax for the same purpose, I am again saying, as you now liked OB, listen to Ripole some day.
I have branded cabinet speakers, branded subwoofer, home made MLTL speakers and OBs. Mine and friends (who listen in my home) opinion is that, for music, Ripole performs quite good. So, the opinion is coming post listening to various systems one after the other on the same day. Requesting thus to listen a Ripole and then make your opinion. A design data, statistics, parameters and net opinions are not the ultimate thing. So many variables are there to change final listening experience, that it is too useless to come to any conclusion without a personal audition.
Having two driver per cabinet for Ripole design is to increase SPL. One should do it only when the rest of the system has SPL very near to those Ripole drivers.
In my case the difference is nearly 9, so I am fine with it. If I have to use Ahuja 12 FRX, I have to go for two drivers per cabinet. And then I would have gone for R907 design (my original starting point for coming to DIY).
Ripole has a big disadvantage of cabinet resonance. That should be taken care.
When I see frequency responses in Foobar and check whether they match with actual output (ofcourse by my ear only), I see that lower frequency till 30 Hz are quite loud yet well defined and controlled.
Good thing of Ripole is quick dissipation of sound. That is another advantage I got while changing the cabinet.
