Hi Markus,

What's your subjective opinion of your Ripole versus H-frame, for your particular setup?

Thanks!

Hi Markus,

one more question, I've read somewhere that you delay your subs.. Did you try using them without delay? Can you tell the difference? Will I be good without delay?

thanks!

If you compare a "ripole" with Nelson Pass' "SLOB", it is evident where the symmetry is - and where not.

If you notch the front output quarterwave, what happens to the back output ?
In a ripole you have the same notch/quarterwave situation in front and back. After all the cone can't move in different ways on its front and back side.

If smooth dipole radiation is desired then the front and back output needs to be as symmetrical as possible.
What is wrong with a subwoofer construction if the radiation pattern tends a little bit to cardioid?

Not sure what you're asking.

Never tried using them without delay.

There is no dipole radiation at low frequencies within an acoustically small room.
Here a dipole essentially behaves like two monopoles with one monopole inverted.

Not sure if this driver is qualified for Ripole use (parameters, vent hole). Did you get in contact with Axel Ridtahler? He can probably tell you right away if the driver works in a Ripole.

Hi Markus,

Which of your Ripole or H-frame do you prefer?

Thanks,

The H-frame configuration uses two 10" drivers whereas the Ripole uses four 12" drivers. This is 3 times the diaphragm size hence I prefer the Ripole for better power handling capabilities and lower cutoff frequency.
