I'm thinking of building my first diy speaker. I'm looking at the Mark Audio CHR-120 with Scotts large classic vented box plans. If the dimensions were changed but the volume stayed the same would the port size need recalculating?
I've got an old radiogram in my lounge that no longer works. I would like to strip it and reinforce it for a large cabinet network/bluetooth speaker project. It's a trade-off that the drivers will be too close together and too low but the size of the cabinet is much larger than what I could get away with in terms of conventional speakers in the lounge so I would like to give it a try.
Best to pencil in the HxWxD, driver location dims you want on the plans and post it [of course block out original dims if a 'for fee' design].

In general yes, but if the box ratios start to become large the box transitions from BR to MLTL and the venting wil need to be lower.

As Greg & Dave said. No big deal, they're a free design, so if you can post the dimensions, I (or Greg or Dave) will be able to confirm. If it's an old radiogram, I doubt we'll have any issues with one dimension growing sufficiently to shift the tuning through a longitudinal eigenmode, but it's worth checking.
Thank you guys. Looking at it further while measuring the dimensions I'm wondering if it's going to be worth the effort, to be honest. It seems a lot of work for my first project.
The dimensions are 112 x 37.5 x 35cm cabinet. With the legs, it's 60cm off the floor. Walls are currently just 1.5cm on the sides and 1cm front!

What does the box look like?
One dimension is significantly larger than the others, it may already be an ML-TL.

- Would changing the dimensions of a cabinet but not the volume change the port tuning?
