Early 2015. 10″ tapped horn “subs” to go with my 2×6″ “top” cabinet, for bass guitar. Also used as bass speakers for house parties at the time. Currently gathering dust, not sure what I will do with these.
These are copies of THAM10 as designed by Anders Martinsson, except with Mivoc AWM104 drivers instead of B&C 10NW64. I don’t remember modifying anything besides the drivers. I went with these drivers because I think they were about a third the price, they have 9mm xmax and they were available in 4 ohm. They model okay down to 60Hz in a THAM10 enclosure – a little more peaky in the bass, but also less efficient outside of the horn response so less noise there and therefore a little easier to cross over. Hornresp modelled response and max SPL at Pmax&xmax with AWM104 (black) vs original 10NW64 design (grey):
They actually sound pretty good for bass guitar with just a THAM10 and the 2×6″ top cabinet, without any crossover. Weight is about 16kg each (10kg wood, 6kg driver). I powered them using a Behringer iNuke NU1000. Iirc, one of the cabs rattles a bit at full volume.
