I think the Megalines might be overkill for your room size (although I did like their sound)... Maybe a better choice from Dali for your needs is to look at their Helicon800s. I liked those too, and they are more practical, IMO.
I concur with the Tyler recommendation by the way, but the Linbrook Signature Monitors are rear ported, so I would not recommend that particular model for your needs. That said, Tyler has a Linbrook Signature System 1 piece model that is front ported, and goes down to 25hz cleanly for about 5K new (for disclosure purposes, I own the two piece, rear ported version of these that sells for the same price and has the exact same specs). Also from Tyler in your range are their top-of-the-line Woodmeres at 10.2K new that would also work nicely (also front ported)... They go down to 22hz, and are amazing speakers in every way.
Other contenders I can easily recommend are the McIntosh XRT-28s (at about 9K used, a fabulous speaker that goes down to 18hz with ease -- these sound great with rock and female vocals in particular), the VonSchweikert DB99SEs (6-7K used -- great all-arounder, that does not take up a lot of floor space), and the Ayon Butterflies at $5.5K new (hard to find, and bass extension to only 38 hz, but *very* clean).
