Best type of Sub to consider?

Eric,

 Would there be any advantage to daisy chaining a pair of sealed Rythmik F12 subs with a pair of the dual 12 Rythmik OB subs?

 However, my room is only 14 ft x 19 and a 7.5' ceiling.

This sub is made specifically for music reproduction, being optimized for sound QUALITY, gladly sacrificing maximum sound quantity to get it. The output of a pair of the OB/Dipole subs is about equal to a single sealed Rythmik. Are you willing to give up 3dB in output to obtain the OB/Dipole sound quality? I was.

 

ajant---Yes! And that is a very good idea, one which Danny Richie himself has done when showing at RMAF (where the OB/Dipole Sub was voted "Best Bass At The Show" multiple years in the recent past), using the OB’s in the front of the room and F12G’s in the rear. The Rythmik plate amp is available in an XLR version (actually two different XLR models---the XLR2 and XLR3), so you can run a long inter-connect from your pre (or the OB sub’s plate amp) to the F12’s at the back of the room.

The XLR2 allows multiple subs to be connected in "Master/Slave" fashion, but that is recommended only with identical subs, not OB’s with sealed subs. That is because the Master/Slave connection disables some of the Slave’s controls, the Master used to set the operating parameters for both it and the Slave sub. But two subs can be connected without the Master/Slave relationship, the input signal reaching the first sub’s amp merely passed along to a second sub---handy if one’s pre-amp lacks enough outputs for two pair of subs. My pre has both RCA and XLR outputs, two L/R pairs of each, so I can feed OB’s and sealed subs separately.
