I did a comparison of various combinations of bass amps and speakers for a recent bass recording session. The clear winner by a country mile was my Hartke 2000 amp into a Trace Elliot 4x10. Both from the Eighties, and in keeping with bass technology of that era, the rig weighs a ton. But nothing else offered the depth AND clarity of this combination. Just goes to show, that when it comes to bass, weight matters!
