A. Looks like cleanest(and most expensive) option is just ordering rebated baffles.
B. Modify the Fostex baffle to fit the A7s, with or without supra baffle.
C. exchange/trade the Fostex for a MA one.
While the Alpair will fit in the same size through hole as the Fostex, there are several reasons why it's not really practical to modify the baffles to fit A7.3:

-The corners of Fostex pincushion frame extend beyond the Alpair's perimeter, even when using the larger ring
- The Alpair's composite resin flanges are considerably thicker than the Fostex, and while some may disagree with our decision on rebating all Fostex frames, there's not much disputing Mark's advice to do so for his.
As well, the general consensus, and certainly our practice, is to relieve the rear side of driver opening for fullrange drivers of this size with a 45` bevel or roundover to reduce reflections at the area that is closest to the cone/surround boundary.

Using 18mm plywood or even "full 3/4" MDF, etc, this combination leaves not a lot of material core for any type of fastener (I quite liked the sheet metal type socket head screws that Mark supplies), and I recommend scalloping the relief around the area of the 4 basket legs. (see attached photo with our dead "fitment sample" A7 basket.

- To successfully rebate the Fostex baffle for flush fitting of A7.3 would require the fabrication of a pattern template, careful alignment of same with the very delicate driver temporarily mounted the existing hole, a sharp pattern following mortising router bit, and just to make Terry O happy, some bondo to fill the corners of the pincushion pattern.

All in all, for anyone with the tools and expertise to to that, it would be much easier to make a new baffle, either full length or removable supra-baffle.


Dave does have baffles available for A7.3 with extra ring in matching BB to the flat packs in question.

O.K. So the pictured baffle ^ is a square, not the full front panel. I thought the baffle ran the entire height of the box. The square baffle in the photo can be used with the exiting front panel? If so, is it a supra baffle or does it fit flush. I am sorry if this is a dumb question. I have not unpacked mine and I have only studied the photos which do not appear to use a square segmented portion of the baffle.
Thnaks!

The baffle Chris posted is a dummy he did to illustrate the cutout on the backside.

well actually as the 4 small screw holes near the corners indicate, it was from one of the supra-baffle panel kits

Dave,

Yesterday, I was in my friends place and we were playing with the configuration of a pair of Frugle Horn with Alpair 7. Just for fun, I placed them just a few feet apart just like it would be if these were desktop speakers and listened. I know thinking of a floor standers as desktop speakers is odd. Yet, driven by my Sabre DAC and Beta 22, this turned out to be a killer configuration. I was blown away, now it is in my head, can't get it out, GAAAH.

Grrr, can't seem to stop cooking up all kinds of devious plans to get myself a pair. How I can convert a floor stander to serve as a desktop speakers.

Dinesh
