magnifier driver

hi all,
         im currently building my maggie and have a few questions.
how much gap should i leave between primary and secondary due to tight
coupling?
i have a 21" primary so i was thinking the driver secondary could be 16"
heavily wrapped in poly or shrink wrap(saran wrap)
i thought 2.5" would be plenty clearance all round as the driver is only low
frequency.
am i correct with this?
cheers
