Pictured is my zHorn back horn design employing the CSS FR125S.
To my ears this driver does well in a small back loaded horn. There is little in the way of a midbass hump created, oh, maybe a single dB around 100Hz. The bass starts to roll off below 60Hz, but has some presence down to about 40 some, with another drop off below this. I am really liking this driver more and more. The midrange is opening up. Besides dynamic nuanaces that convey swing and the performer's emotional intention, this driver has an upper range harmonic integrety. I hear when another musician takes over a melodic line from another. |

Here is a picture of the inside.
Now that they are together, I'll have to play around with the chamber behind the driver, i.e. wall damping. Presently, I've employed a 1/2 inch thick piece of wool felt on the wall opposite the driver. About the design: thinking it is not a highly damped driver, with highish QTs, maybe a larger chamber behind the driver would be best. This is a narrow design baffle that fits into my nearly reorganized room with about 5 feet behind the cabinet, thus midroom. I'd next like to make a wide baffled, say 12 inch wide, back loaded horn. I like a wide baffle because it creats a larger stage image, seems more efficient (with more sound energy directed toward the listener) and easier room placement (room effects are minimalized). About the CSS FR125S driver: no desire, in the least, to move it from my main system. |
