Dipole M frames -_ a look at their benefits

[xrk971]

Try the K-aperture Z baffle dipole (KaZba) = reduced resonance peaks and wide bandwidth.

It provides similar benefits of slot loaded OB dipole: lower fs, higher Q, increased efficiency, but with high bandwidth.

Thanks for the info.
I also tried simple baffle, U and H frame. At the moment i have H frame and they sound good to me.
What crossover point and slope you use between the horn and H frames?

IIRC, the system is set up as follows. The subwoofer crossed from 20-80Hz, the H frame is 80-250Hz and the Oris is 250Hz-20kHz.

Slope is steep.
