Gargoyle, I have not made paper horns to amplify bass, but only to use as "wave guides", to +/- "shape" the sound. My results so far agree with Romy's theory, that the paper horns begin to eat energy when I used them "too low". In this case I used 4-600 Hz with 6 dB roll-off. Of course, when the "wave guide" is also a baffle one must also allow for baffle step roll-off, and the amplifier-type horns would have to contain and direct a lot more energy. I think the paper is easier to work with than wood, especially compared to turned horns, and one might also use paper "mud" to modify wooden horn profiles. I hope you will share your results if you try this.
Best regards,
