I want to try myself to build my bass reflex housing for my Woofer (if it doesn’t work, I can still go to a specialist), but have a few questions about it. 1. I read that you still need an active softness or something at Bandpass. What do I need this or what brings it? 2. I can also take over the terminal from my Emphaser bandpass box, right? This is a plug-in connection, as it is probably common with Emphaser. 3. I have to enter the partition d I can then simply seal it with Sikaflex or something like that? 4. How thick should the cables be inside the case? So I mean those to connect the two coils as well as the two chassis (are 2 SPL Pro 12″ to a DLS A6)? 5. Do I need anything else? So I have to buy something else so that I can build it properly? Thank you, Diddy
