If you look at speaker driver's data, you find 8" to 10" bass speakers perform the best in the right cabinet. An 8" in a transmission line cabinet may be better than a 10".
Cone speed is as important as frequency response; the greater the mass of the speaker cone, the higher the risk of latency. If speaker cones (tweeter/mid/bass) have different latency, sound gets out of phase.
Martin Logan's electrostatics are classic examples of this where they struggle to get bass and panel phasing correct.....personally I never liked the sound of them for this reason. Quads had poor bass, but the phasing was lovely, sorry, getting off topic.
