I must say, your Othorns came out very nice! Do you have a lot of experience with woodwork?
I mostly use Polyurethane paint on my cabs, but the Duratex looks good (You use Duratex rigth?)
Something i have to try out
I currently have four Cubo 18" loaded with Royal Turbomax 1500s.
I need more SPL under 45 hertz, and here the Cubos are a little weak.
looking for other designs the Othorn got my attention, extension below 30Hz and more SPL than my Cubo over 40Hz... Seems to be a good upgrade and also pair up good with two Xtro above 80Hz.
Sooo, could you please send me the plans for the Othorn V2?
My email is: "firstname.lastname@example.org"
Thanks to you, people like me can build powerful and better cabs than the OEM
Good luck with the PaleHorn, looking forward to see some measurements.
