The problem when you use a narrower pattern horn is that it needs to be bigger - this new horn from Ciare http://oem.ciare.com/pdf_oriz_3.php?info=450 also looks interesting ... just a bit wider than the HF950.I suspect you will get good results crossing over at 800Hz or less with a double 10" box .... I know there are issue once you go higher as the 2 x 10" speakers start to "phase cancel" as you come off the vertical axis.
