"If one wants horns and high performance you will need to educate
yourself and may have to do a bit of setup at the least. With horns,
full horn loading is the best way but its also the largest way. If the
horn speaker has a woofer in a box under it you have not heard a horn
system at all.

I very much agree with johnnk's statement quoted above. Horn mids and highs with ported or sealed bass go together like coffee and spoiled milk. My DIY tri-amplified horn speakers use Bill Fitzmaurice designed HT Tuba 1/8 wave 25 Hz folded corner horns crossed over at 200 Hz with a roll off of 100 dB/octave provided by a DEQX DSP. The impact and realism of bass heavy instruments, especially drums, bass guitar, pipe organ, etc. must be heard to be believed. Also the continuity and coherence of the sound from very low bass to the very high highs is truly excellent. This is not just my opinion but is also an opinion voiced by numerous audiophile friends who have heard the system at length on .repeated ocassions.
As equalized by the DEQX DSP my horn speaker's output at 25 Hz is identical to the output at the 1kHz reference tone. The HT Tuba bass horns are only 18 cubic feet in volume.
