Those are interesting ideas. They were level matched, and we achieved the best results while slightly angling them towards the center of the dancefloor they they sounded really good, but as soon we put them straight there was a cancellation on the dancefloor. Vs rephex subs worked in any position

Im no genious but rephlex sub works through the port that acts like a spring mostly and a bare cone whereas horns work by amplifiing and creating the low end spectrum acoustically and it takes a longer way until the sound exits the horn. Also sitting very close to the horn there is less bass then if sitting right next to the port. Correct me if Im wrong

The fundamental acoustic properties of radiation remain the same. What you need to consider is the complex acoustic impedance and the dimensions of all of the radiating elements, including the physical distances to mirror image sources, room modes, and so on, all the way back into the horn or cabinet. It's not as simple as the massive generalisations you're making. For ‘pure’ horns — which a tapped horn is not — these papers are a good start: https://www.aes.org/e-lib/browse.cfm?elib=19427 https://www.aes.org/e-lib/browse.cfm?elib=17969 https://www.aes.org/e-lib/browse.cfm?elib=20265
But you're going to have to dig into serious acoustic texts to look deeper into it. Try Sound Intensity and other books by Frank J. Fahy. Edited by toastyghost - 24 December 2022 at 3:12pm |
