I've got two Kef B139 that I wish to build a Tapped Horn or T-TQWT with.
I've got a design, attached, which I'm trying to improve on. It'll be used for movies so needs to go as low as possible. Dimensions I wish to limit to 2440cm (8ft) length (so I can just sheet sizes of MDF/PLY) and roughly 60cm x 60cm-these can be smaller but ideally no bigger-again down to sheet size. I'm going to build some floor standers to pair with it, thye should reach down to 60Hz with no trouble-so that's where the upper cut off will be.
With bassboxpro I'm a whiz, with HR I'm a muppet!
I'd like to keep the build reasonably simple and a single fold design appeals on that front.
Anyone care to lend a hand?
