Hello all I was thinking of building a pair of buschhorn #2 for my friend who wants a corner load speaker? I saw the buschhorns and the buschhorns #2 and I thought I saw another speaker looking like the buschhorns? I also saw on a web site at one time not the zhorns but, it had the buschhorns # 2 and another pair of horns like it with both plans on it? Is there anyway somone could get me a copy of both plans? Thanks jm

Good grief, the only answer to that is 'how long is a piece of string.' 
It's entirely dependent upon requirements and to an extent personal taste.
If you want a compact corner back-horn, FH3 will beat out the Buschorn in pretty much every area. The original FH was intended to improve on the Buschorn; the general consensus is that it did. And FH3 is a significant step forward from the original FH. It's the smallest box I would be willing to go with this driver if you want any LF output. There are other corner-loaded back-horn designs which will extract still more from the 126, but it depends how big you can go, since they are significantly larger.

I've assembled more than a few pairs of these, as well as fabricated 40pairs of flat-pak kits, so if I might offer some suggestions;
- read the full documentation set, and search for the thread with posted photos of mock assembly, paying particular attention to location of panel damping pads and fill stuffing
- splurge on high quality plywood ( "baltic birch" or equivalent); 18mm (3/4" )for the front baffles and 15mm (5/8") for the rest is fine
- radius or chamfer the rear side of driver cut-out before assembly (rebate for flush mount if you're up to it )
- due to the narrow width, these can be tippy, particularly on carpeted floors - outriggers of some sort are highly recommended
With the FE126, 15mm baffles are fine.

'struth - we use 18mm for the kits to allow for rebating / flush mounting of drivers with much thicker flanges than the Fostex (i.e. Mark Audio Alpair 7, CHP70, CSS EL70)
just please don't use MDF
These plans are availible if interested, they do just right with a fe166en or with some up-scaleing, fe206en! Klaushorn.com
