what is the best driver for wbin box?
I would like as low as possible.
the parameters can I be these?
qts = 027
mms = max 150gr
bl = min 24
xmax =? it's important?
power = min 900W?
fs?
thank you

I have 2 candidates, different from them:
-RCF LF18G401
Mms 182 gr
Le 1.8 mH
Re 4.8 ohm
BL 24.6 T.m
Fs 33 Hz
Qes 0.3
Qms 7.6
Qts 0.29
Vas 268 L
-Faital 18FH510
Mms 139 gr
Le 1.06 mH
Re 5.1 ohm
BL 21 T.m
Fs 30 Hz
Qes 0.29
Qms 13.6
Qts 0.3
Vas 411.9

There are literally thousands of "Wbin" designs, no one size fits all "best".
Then look for the biggest designs with the longest horn path possible. The JBL 4818 drops off below 60Hz like a rock.
The 35Hz Fb (port tuning) is mainly just to vent hot air.
Every doubling of Xmax results in potentially +6dB more maximum output, but also requires +6dB more power.
For an 18" to be stiff enough to handle high power and high excursion in a FLH (front loaded horn) without the cone shredding, it will require more than 182 grams mms.
