Infinity Kappa 63.1i 's in search of an idea

[jackinnj]

One of the young men of the household sold his 1988 BMW 3xx -- he had planned to install these infinity Kappa 63.1i's (6.5", 4 ohm) but with the car gone they now sit in my possesion.

Fms = 71Hz, Qt = 0.71, Vas = 3.28, BL = 2.1; Re = 3.2 ohms

Happy to hear your ideas.

A sealed alignment is best if no sub or high pass filter if it has adequate low distortion excursion for whatever Qtc alignment/power limit you choose, otherwise a ~max flat impedance TL is a viable alternative, as is OB. Assuming Vas is in liters:

TL:

L = 30.45"
CSA = 23.86"^2
zdriver = 10.68"

If Vas is in ft^3:

CSA = 675.61"^2
zdriver = 16.21"

All dims I.d. and approximate. Stuff to suit.
