[QUOTE="Kevin McDonough, post: 212423, member: 10402"] Adding some screen grabs and data, first the hornresp input screens. I'm way less experienced at horn design than all you guys, so of course feel free to point out any obvious mistakes I've made, always happy to learn how to be better. Normal horn with bigger shelf port..... [ATTACH type="full" width="500px" alt="208881"]208881[/ATTACH] Same horn with the 4 smaller round ports.... [ATTACH type="full" width="500px" alt="208882"]208882[/ATTACH] The response from these two......(round ports in black) [ATTACH type="full" alt="208883"]208883[/ATTACH] Cone displacement and port velocities from Bass Box Pro, firstly at 1700w (red obviously being the smaller round ports) [ATTACH type="full" alt="208884"]208884[/ATTACH] And at 3500w, where BBP just begins to consider port velocity a problem.... [ATTACH type="full" alt="208885"]208885[/ATTACH] And as a comparison, Art's suggestion of an offset horn that has about similar volume and similar response..... [ATTACH type="full" alt="208886"]208886[/ATTACH] and the two types of horns compared (offset horn in black this time....) [ATTACH type="full" alt="208887"]208887[/ATTACH] [/QUOTE]
