Good morning @mijostyn
- plywood
- the “port” is just a rectangular hole about 2.5” or 3” x 12” cut into the baffle in front, below the driver. A wooden block is affixed inside the cabinet that I slide up and down to open or close the port, or place in between.
- the Altec crossover is 1600
- The Mastering Lab crossover that I use is 2000. It’s shelved (I’m not sure what the term means, but I know what they are for, 😆) at 8000 also.
- the novel cabinet shape that you use sounds like an interesting approach but it begs the question: all that weight being supported so high off the floor must be supported by something that will have its own resonance issues. ? Might be a bridge too far for me 😬
- I would send pictures but this forum does not seem to allow for attachments.
- I have noticed that some cabinets have a piece of wood at an angle inside the cabinet. This does not. ?
@timlub thanks for that link. I see that this topic has a history here!
As always, thanks again. I’m really learning something here.
