I don&#8217;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 &#8211; 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&amp;xmax with AWM104 (black) vs original 10NW64 design (grey):<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"605\" height=\"454\" src=\"https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64.png\" alt=\"\" class=\"wp-image-1013\" style=\"width:425px;height:auto\" srcset=\"https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64.png 605w, https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64-300x225.png 300w, https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64-210x158.png 210w\" sizes=\"auto, (max-width: 605px) 100vw, 605px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"605\" height=\"454\" src=\"https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64-max.png\" alt=\"\" class=\"wp-image-1014\" style=\"width:425px;height:auto\" srcset=\"https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64-max.png 605w, https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64-max-300x225.png 300w, https:\/\/invar.nl\/projects\/wp-content\/uploads\/2025\/07\/THAM10-AWM104-vs-10NW64-max-210x158.png 210w\" sizes=\"auto, (max-width: 605px) 100vw, 605px\" \/><\/figure>\n\n\n\n<p>They actually sound pretty good for bass guitar with just a THAM10 and the 2&#215;6&#8243; top cabinet, without any crossover. Weight is about 16kg each (10kg wood, 6kg driver). I powered them using a Behringer iNuke NU1000.
