There is no Pensil for the A5.2, but Scott has designed an ML-TL somewhat similar to a pencil. We have built it and performance is good (just a touch less so than the Frugel-Horn Lite)

Great, many thanks Dave and Scott. Will upload some pictures when done. First, buy a pair of Alpair 5 on ebay. Greets

Several months ago I built at least 5 different enclosure designs for the A5.2, including the Giraffes. Having been a big fan of Scott's Pensils and the like for years, I'd be remiss in not saying that if your floor space will allow, the FH lite is well worth a look as well.

I've build quite a few examples of every model in the FH family, and while none are as simple a build as an MLTL for the same driver, I do think they outperform them several ways.

Whichever design you choose, some suggestions:
- it should be considered mandatory to both countersink all of Mark's thick bezeled drivers - but not the new CHS70/Pluvia 7, or the lower priced and less refined CHN70 - , and to chamfer the rear side of driver cutout as deeply as material will allow.
- a decent grade plywood "Baltic birch" etc is worth every extra dollar / Euro spent
- the drivers will take quite a few hours to fully break- in, so assessment of damping fill levels should be made after the 200+ hr point. Yes, that does mean some temporary arrangement to seal one side ( or in the case of MLTLs, the backs) during this interim

Thanks for hints Chrisb. Actually i'm also interested in the FrugelHorn but first i'm not very good in woodwork, second they have to be put in front of a wall max 15 cm between wall and back of the loudspeaker. Anyway, maybe i'll givem them a shot this year. Greets

The cute little design of Scott's that Dave posted above is well worth a look. They are a much simpler build than the curved sided FHs, with a very compact footprint that makes for very easy placement - mind you they can be a bit tippy, so an extended base plate, outriggers, or a stone tile plinth for ballast would be a wise plan.

Sorry Scottmoose, couldn't resist..........

While the Alpair-Driver is beginning with break-in phase yesterday, i'm using the SB Acoustics SB65WBAC25-4.

For that size of speaker impressive Bass down to the mid 50th and overall a comfortable listening experience.

i'm tempted to build a second giraffe for that driver.

well maybe I'll beat Scott to saying this - if using a different driver than for which originally designed, it might well sound decent enough, but wouldn't technically be a Giraffe

In my eyes, it's a Giraffe. A cabinet design is just a description of dimensions, how deep, width and so on, with a specific driver in mind, that was given a name. If you put 'a wrong' driver in it, it's still the same cabinet. How do you call a FrugelHorn Lite with the Alpair 5 Gen2 in it?

Frugel-Horn Lite with Alpair 5.2

But all the frugel-horns have been designed for multiple drivers.
