Macman, the “annoying peaks above the usable frequency range” is something that your specific installation might have in context of your room and your acoustic system location but it might not be a characteristic of tapped horns. I do feel that tapped horns might be more room picky as the radiation surface is very small in them.  In your correct case of dipole it is for sure more room forgiving.



I know my room isnt very good. The tapped design is rather appealing but I couldnt make it work. Im sure they are good for some specific tasks but for hifi, I dont think so. My tapped horns are going out the window.

Any way, I had a friend over the other day who had made his own FIR filter. We made sweeps for every driver, more or less phase and delay adjusted the whole hornsetup and configured the filter and what a difference. I had a minidsp before which according to me, did a decent job at the heart of the setup but I no longer want to reconnect it. The bass is so tight you hardly believe its there somehow. I believe that FIR filters is the way to go with horn setups due to the phase problems caused by the horns themselves. Does anyone have any experience with FIR filters?
