Alpair 10.2 "Castle" ?

cogitech · 01:44 AM

Scott, Dave, Chris, et. al.

The thought occurred to me, since I appreciate so much about my EL70 microTower "Castles" and I am completely blown away by my Pensil 10.2s...

Have any of you ever considered a "Castle" design for the Alpair 10.2?

It would be a large speaker, to be sure, but I can only imagine the dynamics and power!!! The extra upfiring driver would assist the A10.2 with dispersion as well...

If this has not occurred to any of you, then I suggest designing and naming it the "megaTower."

I volunteer to do an Alpha build!

Twin Ma-Ken10.2 can be configured as a castle.

Hmmm.... Two Mar-Ken10.2, duct-taped together, balanced on a speaker stand.

Not sure what would be lower; stability or WAF.

But seriously, what physical arrangement do you have in mind?

The referenced enclosure is part of a paid plan-set for the Alpair 10.2 - two drivers mounted on face of approx 30L (?) typical MarKen style ( side mounted narrow slots, etc). Overall height of working enclosure is 730mm, which clearly need some type of short base, or void cavity (as seen on photo of FE167 version of several years back) . Second photo is veneered cabinet awaiting finish booth.

While these enclosures don't rely on 1/4 w/l action as do MLTLs, the length of port slots on the whole "Ken" series is a critical part of the tuning, and massaging CSA to maintain volume and increase height wouldn't be benign. It would require a complete recalculation, which doesn't follow conventional methods / modeling software.

Mount front facing driver centered approx 130mm from top, you should be able to squeeze the second one on the top.

How deep are those, Chris?

Please note the photos are for an approx 4 year old design for the now discontinued FE167E - there is document with detailed plans and build photos available from Dave. While the overall topology will be the same for Alpair10.2, the dimensions will be different.

That said, the rough dimensions on the enclosures shown above are 299mm W x 286 mm D - my builds were 960mm H less the plinth seen below the reveal strip in photo below. After the first build, they all had input terminal cups mounted on bottom resulting in a clean back panel, and the lower voids were filled with glass blasting media; heavy MFs they turned out to be - my chiropractor loves it when I move them .

Thanks for the info, Chris.

At the risk of offending Dave (I really hope I don't) I have to be honest and say that the "Kens" have never really appealed to me visually. On top of that, they look considerably more difficult to build than many others.

My only conclusion is; they must sound amazing!

You can start with single Alpair 10.2 MLTL designs. When doubled together you can attain a bipolar or a castle as you please. I've done several bipolar MLTLs with both drivers in the same volume and one design (offset arrangement) with a common shared panel between the two MLTLs.

MLTL designs are somewhat more forgiving/easier in tuning than other approaches.

That's an interesting perspective regarding volume flexibility, Jim.

This is really more of a brain-storming session for me than anything, but some day I might just get the urge to buy another pair of Alpair 10.2 and do some experimentation.

How is the alp10 for baffle step? Can it use a little help or is it pretty "full" already. My memory of it, is that it's pretty full sounding.
