el`Ol, Unless I'm missing something, the Fs of 41.8 of the 10" is identical to the 15". The drop in Spl of 1.6Db would seem almost irrelevant....no?? Of course being a HT guy as well as 2 channel, I have a little knob that makes up for small Spl differences. But even so, 1.6 shouldn't be too big of a worry.
BTW I have a pair of the tens for rear surround duty.

I am glad to have put you on this track, excellent paper as usual !
By chance I just got a pair of 15" from Germany for a similar design, A&D 1524, Fs 44, Qts .7 and Cast Frame Basket that will be paired with
Monacor 130X/8 fullrangers passively. All simulated with your Math Cad model and with on paper very similar results. We will see when they are finished. 

Erling,

Thanks for the positive feedback, it is greatly appreciated.

When you are done with your OB design and build the speakers, send a picture of them for my gallery. I don't have many OB designs shown in the gallery.

Martin-

Good work! It's always interesting to see what the "gurus" of the hobby come up with.My next project will be a pair of Alpha 15's and a pair of Neo 8's I have sitting around.Your paper will aid in my design.


Bob-Sic Em!!! good to see you over here at AC standing up for the cause!

Thanks Steve, but I think el`Ol would kick my butt in an all-out debate, he's much more knowledgable.
I'm treading lightly.  Real glad he's had no rebuttal (as of yet) 
I just know how good my rig sounds and have to defend it.
