Such perfect advice, money withstanding. How many of us have done it in reverse? Wow, look, 4 drivers for 300 quid. Bought, collected, sat at home with software and Internet trying to design something useful! |

Sub is going to be taking considerably more punishment than kicks. Think of cone area and excursion, plus larger cabinet size so there's more surface area to resonate. Honestly I think for kicks so long as you've got several braces directly connecting with the baffle you can get away with 18mm by itself. You can double baffle if you want to be uncompromising, but if you want to extend those standards to the sub that will need to be a fair bit thicker. 50mm is definitely overkill. The actual surface area of the baffle isn't that large since it's mostly cutout, and if what isn't cut out is also well braced you should be fine. Extremely thick baffles are sometimes used as a substitute for designs where bracing the baffle is impractical, but anything more than 36mm feels like it's for bragging rights more than practicality - small extra cost and weight for maximum perceived strength, but I reckon most designs with baffles like that have their weak spot elsewhere. That's really what you want to think about before going OTT on any one point - would this wood/weight be more effectively used in another area? Edited by Hemisphere - 03 December 2017 at 5:22pm |

My thoughts exactly. Ill stick to 12 and 18. There will be 8 braces attached to the baffle on both sub and kicks. So should be sound. Nearly finished drafting the braces then onto the ports. Changed them too only thing that is the same is the outer cab haha.

I figured this is probably the strongest way. There are quite a few examples of bracing like this on google. At least this way its just square and rectangle pieces mainly with holes routered out. As for the ports i will just put 1 rectangle one in the space in the center exposed with 2 separate grills over each driver, that way i can do something pretty with the port once i have figured the size and depth for tuning and not just a full grill covering the entire front :) What do you think?? i might just start a new progress thread in new projects and contain everything within there?? |
