If you are not happy with low end then it might be a placement or room issue. Assuming this is not the problem, then I am not sure the low end performance will be that different - it is the same TL design. I have not made a direct comparison - so I can't say much more.
FWIW: Many prefer ported or TL designs whilst a few prefer a sealed box type bass. If you want bass resolution and speed (very articulate and will give different sound on each track and such that you can discern the slightest subtleties between pressure on the hits on a kick drum) then really I'd go sealed box (in a critically damped or overdamped design) rather than TL. Many large ported monitors are designed that way - the port is not used to increase bass extension - it is just used for efficiency (allows bigger woofer motor in same size box).
