Bear in mind these are older paper cone/metal center BW's. Lots of smack your face mids - a little too potent for my tastes now. This really shows on open back combos (like the Mace) but the 4-12 enclosures help soften them a bit. Also, the older widows are not very strong when you crank the bass. I've had to re-cone 4 of the baskets (they tear out near the voice coil). The fact the voice coil/magnet can be removed (allen wrench) makes basket replacement a snap however.
I think the new BW cones are much smoother with greater power handling. Have considered switching out all the baskets to the new ones, but.....$$$$
I once thought a "Sweeping Arpeggio" was an Italian janitor.
