I do agree Jeff. The majority of available programs can not take cabin gain, driver and port placement, distance, etc into account. Most will use the...

Looks like a fun project. You're torn between:
1. keeping the woofer and mid close to each other for phase reasons, and
2. putting the woofer...

option 2 I think would be just fine. I like the shelf idea and might do something like this Unger one of the cabinets in our new kitchen.

Read the stickies at the top and go from there.
These are really not two drivers that are going to mate up well. The woofer is pretty much done...

Dustin, I doubt dad is going to let go of the Ultimax. The DVC is still a great sub by its own right. The amp that Johnny has is a great match for...

Yes, you can add inductors in series. Yes, you still need to observe the rules for inductor orientation. The best thing would be to unwind a 0.10mH...

It LOOKS like there maybe a rear entrance by the stage. Hope so, trying to move 125xlb woofer cabinets will not be fun on those stairs!
