Default 1/4 wave length vs 1/2 wave length?

How would building a 'transmission line' as a 1/2 wave in length
versus the traditional 1/4 wave in length effect the outcome of the

Would it still sound the same?

Thanks for any and all responses in advance

Yes it would change the resonant frequency of the cabinet. You have to design things with the laws of physics in account. However, you are free to go crazy and experiment but the results still depend on natural laws.

If the terminus is open, it's still a quarter-wave pipe. A closed terminus would be a half-wave resonator.

All have a 1/4 WL fundamental, but the 1/2 WL resonators [open, closed cone pipes] have both even and odd order harmonics whereas the 1/4 WL resonators only have odd order harmonics, so no, they won't sound the same: Resonances of open air columns
