Horn Speaker

thingiverse

Speaker enclosure, topology based on Frugel-Horn mk3 (https://www.frugal-horn.com/FH3.html), a crossover-less speaker with full range Alpair 7A. Printed on CR10S with 0.6 Nozzle, mostly at layer height of 0.4 with 10% infill. Speaker mounting holes for Alpair 7A gen3, but the design accommodates other drivers in the same category. Print all parts, glue together with epoxy, back horn damped with sonofill (pillow stuffing). Adjust down horn dampening as needed, I added some under the speaker mount to the choke point. Printed, applied spray filler, sanded down and painted with furniture paint. These speakers sound very nice and look interesting. Due to unidirectional horn dispersal, these fill a room rather well, also bass response blows people away. You may want to mirror speaker enclosure elements for the second speaker to achieve symmetry for speaker terminal placements.
