It was in the "old" Super Pensil box, in fact they took the A12s out so I could listen to the A12Ps. Probably this box was not optimal for the A12P yet it was already very, very good.
Much, much better than most of the Fostex speakers in my opinion.
And I heard more details than with my quite ok Beyma coaxial-based speakers.

I wonder if the small bookshelf designs that I saw in other threads would need a baffle step filter. The sound in the wider Super Pensil was very good and balanced without extra filters.

As an aside, they had Lowther TP1s playing as well, and they were very nice too, without the "shout" that I feared. But inpractical speakers !

Not really -not, at least, the one I did, unless they're well out into the room, in which case you presumably wouldn't want a standmount in the first place. They're not going to shift air like an Altec 604, but within the constraints of a smallish standmount & a 6 1/2in wideband driver, they do a solid job in the kind of small - medium spaces they were intended for.

Hi all,

I have some bass reflex (rear ported) here that have damaged drivers and wondering how the Alpair 12P would fare in them.

I don't have details on internals but they are:

Dimensions: 23"H x 11.5"W x 11"D

Port you can easily fit adult fist through. 30 pounds each.

I was going to post something like "Wouldn't that be like retrofitting a V-12 Ferrari engine into a trash collection truck?" but I won't.

Silverhair + tricorder + inane post. Yup. Time to turn in the towel.

I wouldn't call a 92db/w driver a Ferrari either...

Assumming 3/4" material, twice the volume i'd be comfortable using for A12.2p

Ok, volume in the low 30's, a little big for the A12p in a BR, but not the end of the world bad.

So roughly a 4" dia. port? Somewhere around 8-8.5" long would do it. If it's a lot shorter, you may want to retrofit a smaller dia. longer port into the box. Would work as a "break-in" box while you build something better.
