Ha ha, told you I'm new to all this hence the confusion. I'd rather ask and look silly than build wrongly.
Ok, it is a 'normal' boxed enclosure with a rear vent at the bottom with the internal dimensions of 135cm x 29.1cm x 29.1cm. How big should the vent be, is it 29.1com x 29.1cm? Are there any internal folds within the enclosure? Thanks.
If it were me and I had another pair I would really like to hear them OB with a helper woofer. Back when I had those, OB didn't make sense, plate amps weren't yet invented and I no-could afford extra woofer anyway, so I just stuck them in a box. Never did like them.
If you plan on a box, GM's your man to get the best from them.
EDIT: They were my first pieces of Altec. Didn't know what all the fuss was about back then.

It's my bedroom.
OK, I just don't equate 'bedroom' with such a complex, wide BW system since I only do two things there and listening to music isn't one of them
, but whatever 'floats yer boat'. Not knocking it, just surprised. I guess if I'd had bigger bedrooms over the years I might have put bigger ones in though. I did have A7s wedged in mine the last summer I lived at home, but that was a parental mandate.
Greets!
No, as I originally stated, I recommended it be on the rear for WAF reasons. I mean a big opening stuffed with insulation wouldn't be acceptable looking to most folks, though of course you could cover it with grill cloth.
No, a MLTL would have a smaller vent to mass load the pipe (TL) to a lower Fp (tuning). With such a high Qts though, this isn't considered the way to best pipe performance, but if you want to experiment with a smaller vent opening you can to see if it sounds subjectively better, though I wouldn't make it < ~52 cm^2.
