Design Notes:
    This center channel was created to match and aid the 1.618 3-way towers during surround sound reproduction.  Its main focus was to match the upper chamber of the 1.618 towers.  However a ported enclosure was chosen to aid in the extension of the response.  The same xover point was used as were with the 1.618ís.   On a side note, it was specially constructed to fit perfectly in my TV stand.  For smaller spaces the 1.618s can be used.
     In conclusion; Perfect!  My home theater front is now seamless.  The center matches very well with the towers.  Dialogue is very clear and has an excellent warmth quality to it. 


Additional Notes:

     Please visit diyaudioprojects.com to view this design in more detail.  All the details are available for free to build your own pair. If complete drawings are needed; they are for sale.  If completely built crossovers are needed; I can build them. 

    Please note that the SD1.1A has been discontinued by HiVi and is in limited supply.  Please use the Q1R as a substitute.  I have gotten reports that the Q1R actually performs better than the SD1.1A.  Cleaner and smoother.
