Comparison of designs

More or less.

The cabinets will have different diffraction signatures (all the way down thru the transition from 2π to 4π (that actually doesn’t happen on Poplar), and will load the room differently. That is much the case across all speakers.

The box primarily shapes the response at the bottom. With its heavily damped response, and the room gain it assumes, Poplar should dgo lower.

Poplar, and Aspen its sibling (P11), where designed to fill a specific role. The person that needs the speaker to hug the wall.

I do need a speaker that is a "wall hugger"...WAF.

I see from the teaser plans that the Alpair 10P or the 10.3 are spec'ed for the plans. Which one would is best suited for this cabinet?

And how are the plans purchased? There doesn't seem to be a "store front".

They are both fitment for Poplar. The 2 drivers have different voicing, some like one, some the other, 6 of one, half dozen of the other.

One might say the A10p is somewhat more romajic with a vintage top end (not that that is likely to help), the A10.3 more analytical. A10p is a bit more sensitive, the SE tube guys really like it.

If it means anything i did about twice as many A10p as A10.3. Chris ended up with 3 x A10.3eN across the front of his system.
