[QUOTE="066, post: 8823976, member: 687517"] Hi my name is Dylan. Thanks for looking at my thread. Like the title says, I’m working on a center console. I have some probably basic questions but I haven’t been able to find what I’m looking for on Google. I am using WinISD btw. Vehicle : 06 F250 Crew Cab Location in the vehicle: center console w/ subs firing into rear passenger footwells Space available (Length x Width x Height): ~15x15x47 outer Subwoofer make and model:NVX VCW122 Subwoofer Size:12” Number of Subwoofers:2 Type of Port (Kerfed, Slot, Aero, etc.): diy aero What type of music do you like?: everything except country Is your goal SPL or Everyday Music?: 90% everyday listening Tuning Freq (Hz): 20-25 hz Volume : mid to high Questions 1) What would be the preferred port location in a situation like this? Would it be bad to face it towards the dash? 2) My plan is to integrate either 4” or 6” PVC into the 3/4” MDF box and roundover the ends. Is 1/2” roundover enough? 3) Tuning to 25 hz, port velo is peaking at 31ms. Is this acceptable with the flare? I hear 36ms is the number, just double checking what the consensus here is. It peaks at 25ms when tuned to 20hz. 4) I also hear that when tuning in WinISD, you generally end up with lower tuning than what you expected. Is this still true? I’m sure I have more questions but I’ll leave it there for now. I appreciate any help. [/QUOTE]
