I am getting ready to build a "little" BIB project. These will be used nearfield as desktop speakers. I have a couple of questions but this is what the spreadsheet spits out:

Questions:
At what height do I mount the driver (remembering that these will be sitting on a desk, I read somewhere lower is best)?

How much stuffing is used?

How low will these go?

Thanks,
Ed

The measurement to mount the driver is "zdriver." Measured from the top, you should mount your driver 14.609 inches down. I believe the stuffing should be placed in the section of the line above the driver, but you can try different amounts and locations to see what you like. Sorry, but I can't answer your question about how low it can go.
