I fairly recently heard an 8 inch Fostex driver mater to a vintage horn tweeter it was a fantastic combo but a one off design. I've also heard and liked Charney Audio speakers.
How much does rear horn loading add to full range driver?
Found a tower speaker using a single 3" full range Tang Band titanium driver. The rear wave is horn loaded via the 43" tall tower. The speaker had some pretty good reviews.
I listen at lower volumes in a smaller room.and actually have some Norh 3 drum speakers using a 3" Tang Band driver. The enclosure is roughly LS/35A size and ported. For vocals they are loud enough. Norh claims they play down to 75hz.
How much volume is gained by horn loading the rear wave? Would a horn enclosure 43 x 9 x 6" inches be likely to play lower than a ported shoebox size speaker? These wouldn't be my main speakers, just an interesting addition.
Thanks,
