Guest David H Posted November 18, 2013 Share Posted November 18, 2013 The K-402 is a 2" horn the size of a refrigerator, the Radial I built is a1 inch horn 6"x18". Dave Quote Link to comment Share on other sites More sharing options...

coolhandjjl Posted November 20, 2013 Share Posted November 20, 2013 Does wood normally have a different characteristic sound compared to aluminum? Some people complain about ringing in aluminum or cast metal horns. Others complain about honking in plastic horns. Now whether or not those issues indeed exist with metal or plastic horns is something that will be debated until the end of time. The advantage of using wood or mdf is their resonant frequencies are below the horns range. So no debate needed. Dave is indeed the new horn guru. I've learned much from his tireless efforts. 1 Quote Link to comment Share on other sites More sharing options...

Thank you for the response. I assume that the thickness of the wood would make the resonance drop even lower... So the resonenance frequency would be lower than the cabinet resonance frequency.

djk Posted November 20, 2013 Share Posted November 20, 2013 (edited) Play some FM interstation noise at a moderately loud level. Push in the tape monitor button (or mute). Listen to the decay of the noise. This is what is being added to the music. Some metal horns make a 'schwing' sound that actually rises in pitch as the noise decays. A well damped horn is dead silent. Edited November 20, 2013 by djk Quote Link to comment Share on other sites More sharing options...
Deang Posted November 20, 2013 Share Posted November 20, 2013 The advantage of using wood or mdf is their resonant frequencies are below the horns range. Maybe with MDF, and maybe if the wood is thick enough -- but if thin bendable wood is used, it resonates and is both measurable and audible.

Guest David H Posted November 21, 2013 Share Posted November 21, 2013 (edited) Eagerly waiting for a review of these horns. See that, not you made me work. Here is a shot of the driver adapter, I used Conical expansion to mate to the rectangular throat.

Schu Posted November 21, 2013 Share Posted November 21, 2013 well... it is at least interesting Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 21, 2013 Share Posted November 21, 2013 Frequency response done in room using FFT and calibrated mic. Not anechoic!!! Driver is Selenium D-220-Ti Low frequesncy FR done using Selenium D-250X in room. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 21, 2013 Share Posted November 21, 2013 (edited) well... it is at least interesting Yes, this was listening test of the radial horn set atop my Econowaves. The radial horn was significantly more coherent than the original Econowave horn. Dave Edited November 21, 2013 by GotHover Quote Link to comment Share on other sites More sharing options...
Deang Posted November 21, 2013 Share Posted November 21, 2013 "Coherent". I love that word because it's easy to understand and conveys so much. I like "cohesive" too. Does the music sound like it's emanating from a singular source, or does it sound somewhat disjointed? Sorry for the incoherent, disjointed rambling.

I haven't had a lot of time to listen, however I do consider them cohesive. Does effortless work for you? My initial impression of the sound - They are far better than expected. Definitely 2 way capable. Dave Quote Link to comment Share on other sites More sharing options...
Rudy81 Posted November 25, 2013 Share Posted November 25, 2013 Dave, I'm curious as to how you are setting up your mic relative to the horn when you take measurements. I just took some measurements of my own build and seem to have trouble getting accurate reading in the higher frequencies. Are you taking these measurements outside, or are you inside and limiting the impulse window to get your readings? Quote Link to comment Share on other sites More sharing options...

Please post more comments fater you have had an opportunity to do more listening. Go ahead and use any adjatives that you want, we won't tease you (well except Dean, but he is like Mikey from the old Life Cereal commercial).

I took these over to Johnny 5's place yesterday, we spend 3-4 hours listening. I find the Radial horn open, dynamic, detailed. He likes it hey Mikey!!!!!

Guest David H Posted November 26, 2013 Share Posted November 26, 2013 (edited) What is the crossover Fr? This horn has an Fc 0f 400 Hz, should be crossed 600 Hz or higher I have been using it at 1k. Here I loaded a Selenium D250x to see where is loads. Dave Edited November 26, 2013 by GotHover Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 26, 2013 Share Posted November 26, 2013 600hz? Can these be used with a La Scala bass bin? 500hz for the La Scala I, right? The frequency response that you posted last week looks like it can make it to 500 hz. I want to use JBL 2470s. Thanks. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 27, 2013 Share Posted November 27, 2013 I think the Lascala is good to 600z, that is where I would start. JBL 2470 nice! Dave Quote Link to comment Share on other sites More sharing options...
