3015LF Enclosure Plans - SS15 with cone correction

[LORDSANSUI]

where you put the driver on the x5b ?

Maybe it's better to create a different thread to discus the x5b.

The driver is placed where the color changes, the driver placement are defined by the models available on Hornresp, in this case it was the CH3. Check attachment #1 and remember always to check System Model.

DL for doing sims

The sim output are available at the spreadsheet page inside the CAD files that you download, the user can also export the TXT file to hornresp with all automated options available.

Check the 1st image from Tips and tricks session or attachment #2

have you saved or have your plans of your moded SS15 ?

There was a thread as you can see below, but unfortunately the images were loaded into another website that are no longer available :/

and
is kind of strange that the NZONE SS15 is 224L vs the original SS15 that is 230L but the NZONE still hit lower
maybe the diferent panel layout inside

Width play an important role for volume, mine are wider for instance.

The FreeCAD model for the THSS-1 is the model I built.

What counts for low frequency is the horn length not box volume. Volume will contribute more to SPL.

10-4

The easiest way to compare horn length is to looking to unfolded model as you can see below.

So you can check 2.41m is a 1/4 wave length of what frequency?

 

[maxolini]

if we take that at 20C , sound waves traverse air @343m/s

it will be around 35Hz
