    Construction

    The Sabourin Horn consists of flat plywood panels cut with compound angles to form a miter joint.  This produces a clean appearance even from the rear of the horn.  The miter joints also provide a very strong finished assembly. 

    These plans include five different versions of the Sabourin Horn... 

    1293 --- 300Hz 2" throat version (1.4" with the throat adapter) 

    1294 --- 300Hz 3" throat version (for use with 3" fullrange driver or other) 

    1295 --- 300Hz 4" throat version (for use with 4" fullrange driver or other) 

    1296 --- 300Hz 6.5" throat version (for use with 6.5" fullrange driver or other) 

    1297 --- 300Hz 8" throat version (for use with 8" fullrange driver or other) 

    1298 --- 200Hz 8" throat version (for use with 8" fullrange driver or other)

     Sealed rear chamber 

    The drawings feature a sealed rear chamber (Ref No. 1299) which can be altered to suit your specific driver.

    Sabourin Front Horn DIY Plans

    Hi. Besides my bad alignment on my miter saw everything was good. I do have a question. When u make an enclosure to do a horn loaded speaker, the enclosed seems very small. Is that common? Would it not have to much resonance from such a small box? Thank u if u can clarify that for me.
