I bought a pair of diy'd speakers a few years ago consisting of vintage goodmans 15" and their ARU vents, must say I was impressed at the time
The sound of a big box, better transients, and lack of the reflex sound, what's not to like ?

I think I've got a similar type of sound with my red semi OBs... which is sort of a similar type of path for the rear sound wave.?
The tube manual is quite like a telephone book. The number of it perfect. It is useful to make it possible to speak with a girl. But we can't see her beautiful face from the telephone number

Thats the nice bit steve, that they dont seem to sound like a reflex box at all
The intrinsic characteristics are the same, but the sound is more 'complete' for want of a better word.

Yes,
I was telling Ant while I was at his place, that the up-firing APR vent he’d made was producing a similar effect to that from the ones on your speakers. The improvement in air and space, was immediately apparent as soon as I walked in.
Because he had made the tops as decorative end caps, like the Gale 401, it was easy to quickly A/B the speakers, with and without the vent in operation.
Emma said it was like putting the performers back in their boxes when the tops were on and blocking the vents, which I thought was a perfect description.
On my 12in speakers, I put the APR vent in the bottom, so as to get a bit more extension at the bass end, so I don’t get the height and space effect, but the tonal balance and freedom of Ant’s speakers is strikingly similar to mine, now he has done the aperiodic conversion.

That's nice to hear, my view is that the big vent gets the speaker closer to the open baffle sound, but without the open baffle compromised bass.
It's all compromises, but that's the best one in my view..
