So for a change it was not rain all day in Denmark yesterday, adn we could go outside and make a couple of shots of the cabinets we put the Alpair 6.2p in, please see below.

It is a 4.5 l hybrid bass reflex and TL tuned to around 50 Hz with internal TL damping.

The Alpair 6.2P continues to impress, in the ongoing test we did come about a couple of tracks that we not good. Ryan Adams Firecracker has a very aggressive mouth harp, that just was a torture for the ears. The Alpair 7's did not sound so aggressive, strange normally the Alpair 7 would reveal even more detail. Maybe Ryan Adams ment it to be torture , take a look.

It had to come, yes it is a pre-manufactured box, that we have used. It happens to fit the Alpair6 beautifully acoustically, no black hole mystery here :-)

It kind of looks like an existing port on the front was sealed and that a vent was put in the back manually with a router.

Well the box was originally built for a two way system, but fitted with budget drivers, to us a polite term. The woofer slot fits the Alpair 6 nicely, the tweeter cutout is covered with "the black thing". This is a prototype, it is actually cheaper to buy these speakers and yank out the drivers than it is to have boxes built. The rear vent and channel inside is actually quite well designed. Still looking for a better way to patch up the tweeter cutout.

isnt flush mounted important?

i've made henkjan's tl with alpair 5 no flush mounted, but still perform well, and then i made alpair10&5 with flush mounted, which a little difficult since the cutout of the 5 is too small radius of my router trimmer, so need to do it manually.
