Hello Forum. First time DIY subwoofer builder taking a crack at a full Marty, thought this would be a good place to ask about the gaps. Looking to spend $500-800 for a noob woodworking project that will give me something to look forward to after a long day at the keyboard. So far... From what I've read the UM18-22 is a solid driver for the price. Likely go that route. The iNuke 6000DSP doesn't seem to be available anymore and I was hoping you folks could recommend a comparable. Also looking for actual cut plans for the cabinet. Apparently the AVS member "chalugadp" has retired from offering flatpacks, so I'm looking for an alternative. Complete cut plans would be great, I've people with the tools and are willing to train me. If a full flatpack is available that's cool too. All suggestions welcome and thank you in advance.
