These are truly superb woofers, with a 4" diameter phase plug for cooling. They also have a T-cut pole piece with a shorting ring beneath, so the inductance linearity between that and the aluminum phase plug should be excellent.
As a bonus, these are some of the coolest looking woofers around. Volt probably gets the nod from me with the front motors, but the magnums live up to their dirty harry namesake with cojones to spare.

Yup, cabs are from 4648a, unaltered.
I stuff a port for 28hz tuning instead of stock 40hz.
I measure 25.5" wide x 39" tall x 17.75" deep.
