Hellooo
A few years ago I built a minirig for the house/BBQs and the park (although never got round to that bit) I originally built some mini scoops and a reflex kick bin more for the aesthetics rather than a practical reason. The scoops were based on a scaled down eminence design and sound decent but are mainly higher bass than much useful sub. The kick bin I tuned quite high to make it more suited to kick when now I'm thinking this would have been better as Sub. Both are loaded with Beyma 8BR40/N I'm now planning to go with a single design to play the full sub/bass range but am I looking to maximise SPL as I finally plan on making it mobile and taking it out and about while the sun is still here . Does anyone have any suggestions on a design that I could use? Driver specs - https://www.beyma.com/getpdf.php?pid=8BR40/N Current setup: |

I'm not too familiar with transmission line designs if i'm honest, is there a way to model predicted response with them similar to winisd etc... the little bit of reading i've just done says they're more a trail and error kind of job

Hornresp has that capability, there's even a wizard where you can set up the basic layout, under Help>Input Wizard (or just F7)

They are not trial and error... Theres a nice paper I read up on and had a blast at myself using a pair of 10" drivers. Can't find it at the moment but we'll worth a read

The front could look the same... if you made those "scoops" deeper and tucked a long transmission line into them with the final leg of the pipe opening up to LOOK like the front of your nano-scoops... that should increase your bandwidth a little enough to get some half decent bass without pushing the driver into meltdown... bolt them together as they are and stick wheels on the back and it SHOULD be easy to transport! |

I like that idea as it will keep the interesting look as well, going to have a play around this weekend and see what I can come up with
