Default Alpair 8

Hello Chaps,
Getting my second wind today so here goes.

The Alpair 8 driver will hopefully be a complete departure from previous models. This driver is designed to a "system" unit. In future, dealers and end-users will be able with the minimum of skill to:

1 - Swop in/out Power-Trains.
2 - Swop in/out motor sets (magnet/motor sub-assembles).

As you might begin the imagine, the potential permutations for power-train and motor set choice could become user-significant. No more chucking a driver away should the kiddy or cat ding the cone. Just order up a replacement power-train (lets see how many of you remember the components of the power-train).

The picture shows you the primary frame sub-assemblies, including the "clam spider retaining ring". Dreamed this up while recovering from the anaesthetic, that stuff was good! Mr Chui helped along with the rest while in my hospital bed (he's a great guy).

Questions...........go ahead but give me time to answer, I'm not yet firing on all cylinders.

Cheers
Mark.

What a great idea!..........extending upon this, couldn't you make the following components " modular" 1) surround, cone, VC 2) spider 3) Motor assys'
The surrounds could be either pleated(variable) half-roll sorex(sp?) or ?
A choice of cone material, VC length
The spiders of variable compliances(An interchangable thin nylon threaded ring at the base of all cones & spiders.
Motors variable in strength(Gauss), and or?

With the basket with your clamping assy for the spyder & some style clamping for the outer edge of the surround?????????? All "standardized"

So very many versions would be possible........testing all the combinations would be sheer fun.????????????

Modular = great idea Mark.

@Rick; I suspect this is what Mark ultimately has in mind.

+1.

Mark, great to see this concept getting closer to reality. Tweaker's delight.

Scott - probably more cabinet work for you sir, as driver parameters are likely to change with different components?

That they will. Not necessarily more work for me, since I can't churn out box design after box design for every possible combination (depends how many options there are); no doubt I'll do a couple for the A8, but realistically, I'll probably have to aim for whatever the default / most popular component combinations turn out to be rather than trying to cover all angles.

Yes Rick, Scott, Zman (Guys)
You've got the idea.

Hopefully we'll get more feedback as to what combo's members/diyers would like, (no worries chaps I am improving so please feel free to make comments).

This driver is important, the thinking and sentiment behind this design is to give "you"...the user more choice, more control over the build and help get the sounds that you want.

Cheers
Mark.

Mark - glad to have you back

now that this is finally on the table get ready for a flood of advice and requests for cone materials among other things - such a experimenting with different formulations of paper -

Any idea what sized frame will be used for this? Will it be the same as the Alpair 7? 10? 12?

I would anticipate none of the above. It's an Alpair 8, so as a matter of extrapolation, the frame dimensions will likely fall somewhere between those of the Alpair 7 and the Alpair 10. The former has a bezel of 135mm with the cover, the latter 165mm, so something around the 150mm point seems probable.

Since you're asking for what people want Mark, here's my initial suggestion: the arrestor should be carried over in the new unit's suspension options if possible.
