‘Best’ is a ‘moving target’ dependent on many variables, but a simple tower floor-standing vented alignment [aka MLTL] seems a good choice:

52” H
50”^2 WxD
driver down 15.25”
vent down 41.625”
vent diameter 2”
vent length 0.75”


Thanks GM, that seems like a tall bad boy!
Could you run the width and depth dimensions for me again... is it 5" for W & D?

Wonder why no Mac software...very odd. Maybe I need to buy a cheap PC

GM, can you fold/taper that MLTL and get comparable results?

You’re welcome!

50"^2 = 50^0.5 = ~7.07" W x ~7.07" D, but you can change either or both just so long as they sum to ~50"^2.

Using the Golden, or an acoustic ratio is normally a good plan to average out its internal eigenmodes [standing waves] to keep damping to a minimum, but again, this cab is small enough that damping will be sufficient regardless of its WxD dimensions.

I guess Mac users prefer to buy B0$3 or similar concept speaker systems rather than DIY.

Sure, though tapered [TQWT] would require a redesign. If you just want tapered to make the internal baffle/brace be offset, then make the closed end ~34.66”^2 and the vent end ~75”^2 or some mean value between the two.

This theoretically yields a slightly more efficient vent gain, so you might want to try a 1” or longer vent.

Still trying to figure out what I want to do. The more I read, the more boggled I get.
Wondering now if I should wait til the Alpair 10.2 is in stock ( somewhere) or wait for the 10.3. The more reading on the Tang Band I do, the more I think the 10.2's are a better choice, quality/sound wise... although more dough.

I guess a cheaper driver would be good to practice with.

If there are any people on the forum who live in the Vancouver area, I wanted to ask the best place to get baltic birch from ( the good stuff). I only know of Windsor Plywood.

TIA

Hello from across the Patullo. Can't help with Baltic Birch nor can I make a suggestion about the Alpair but maybe planet10 will chime in and help with your decisions.

Hi Cal, boy are you correct, I am a stones throw from the Patullo! If I was any closer I'd be sitting on the bridge deck.

I'm just thinking the the MA drivers are better quality and there is more info/plans for them. Couldn't find too much on those TB's I was lookin at.

So with that said, I wonder when the 10.2/3's will arrive... July? Aug.
Hurry up and wait....

lols* Its kinda true...

Ive installed Winebottler with Wine + X11 to run Hornresp and Akabak. Couple of years back on an iBook I managed to get Mathcad going with X11 so I guess MJKs mathcad sheets is a probability

Theres issues with import/export functions with Winebottler and my swedish keyboard setup doesnt allow me to input decimal points in Hornresp. Other than that its running fine

I have the W5-1611 and Im learning to run sims for it. Definitely gonna try out your suggestion for a cabinet. Thanks

Regards /Bo

Thx Bjorn, that looks interesting also.

What is your listening review of these TB?
Do you have any pictures of your project you could share?
I'd like to see it finished !
