philray Posted November 15, 2015 Report Share Posted November 15, 2015 Hello all, I have been trying to locate the build and cut sheet for either the Othorn or Gjallarhorn. I have looked and looked to no avail. Even tried digging for any and all pdf files with no luck.Thank you kindly for any and all help. Link to comment Share on other sites More sharing options...

Lucabratsi Posted February 9, 2016 Report Share Posted February 9, 2016 Hello, I'm new to this forum, great place. I've been building speakers for 20 years, and built just about everything except long folded horns like the Gjallarhorn and Othorn. I have 8' line source arrays for my front and sides, and need some serious upgrades for the subwoofers in my 26 x 28 HT room. Can I get the plans for these base hours? Just curious why Luke went with both horns? Kind Regards, Luca Link to comment Share on other sites More sharing options...

The Othorn is much more efficient than the Ghorn from 25hz and up, and it also doesn't suffer from the horn resonances that required a lot of EQ to tame with the Ghorns (and even after EQ the Ghorns didn't sound good enough for me for music). However, by 20hz the Othorn doesn't have much useable output, and that's where the Ghorns came in. With the Ghorns I could hit 134db at 15hz at the seats. Combing the two gave me my favorite bass for music I've heard so far, and also extended down to ~12hz for movie content. Link to comment Share on other sites More sharing options...
Lucabratsi Posted February 9, 2016 Report Share Posted February 9, 2016 OK, makes sense. I am looking for the lower end, as I have quad amped using the DBX 4800 Driverack active management. Crossovers are set at 800Hz to my array of BG NEO8PDR (x9), 150Hz to the Audax HM170CO (x12) array, 50Hz to a 3X18" array, then to my current subs which are the 18" competition Audiobahn in a box. I am looking to make the horn sub for replacing the Audiobahn box (reflex), and crossing over at or near 40-50Hz. Do you use a high pass filter on your bass horns to limit the unloading?
