It's a bit tough to select a "quality brand" from manufacturers that haven't made products suitable for bass guitar in DECADES. All 4 of the brands mentioned above have not manufactured or sold bass guitar drivers in over 20 years, Gauss has been gone entirely for over 30 years, Cerwin Vega, JBL and EV got out of the MI driver industry between 20 and 30 years ago.
Yes, details matter including choosing suitable AND AVAILABLE drivers.
But you can still get the Jensen P15N out of the Ampeg B15
