Looking for a great front ported bookshelp speaker recommendation

I have same setup. I tried Mirages. Good. Guru's better. Linn Sara Isobarik, good as well. But the best I found and still use are Audio Note K. I have them horizontal on iso puck minis.

NHT Hifi sells their C1 and C3 acoustic suspension speakers (no ports) that are designed for book shelf and wall mount use.  These speakers sound good and are reasonably priced. You might want to consider adding a subwoofer if you have to use speakers that are on the smaller end of the spectrum.

Why don't you just get some Sonos or other type of wireless speakers if you're going to stick them in a cabinet?  

There are, of course, many great bookshelf speakers.  However, some of those great speakers will never perform well in a cabinet.  Some, however, do seem to excel in this suboptimal location.  THAT is where you need to focus your research.  I do recall reading about several speakers years ago that do exactly that.  The Madisound Loki Mk3 is one such speaker.  Check it out.  All kind of upgrade options.  Another kit they carry that might perform well in your large room and still fit on a bookshelf in their Seas A26 kit.  

If you have room adding a sub would really help.  Maybe keep this in mind with your speaker budget .
