Does anyone out there in that huge world we live in
know the magnet weight on an orion h2.2?

Depends on what size you are looking at.
10" Gross weight is 40 lbs
12" ..................... 43 lbs
15"....................... 49 lbs
I would estimate the magnet to be about 80-85% of gross weight.

Interesting, but they are all about the same weight. Kinda makes you wonder if they really need one that is 20lbs.
Hmmmmmmm

It pretty much boils down to flux density (magnet stength) and the type of motor structure employed. To create large cone excursion and still control it, takes a strong magnet and a stiff spider.
In the good ol days, Alnico V (Aluminum, Nickel, Cobalt) made a pretty strong magnet in a compact size and weight. Low and midgrade ceramic magnets, need to be much larger to develop the magnetic flux field required. However, if price and size were not an issue, then Neodymium could be used. Very strong magnet in a small package.

Not only that, but magnet size also was considered due to BOX size. A tiny magnet will work wonders in a large box, however, trying to produce 1kW in a 1.5 cu ft box requires a very high energy magnet. In a 3.5cuft (like home towers) it doesn't take much at all.
I think that's where magnet size comes into play. How much flux do you need when you can have a 3.5ft^3 VENTED enclosure? it is a tradeoff
