@tuberist , correct, They port out the bottom through a secondary enclosure into a 360 degree slot. I believe this is a method of tuning the port to work over a broader band. Not totally sure on that. It might also dampen port noise. Regardless, in todays world you can make any sealed design do whatever you want in a distortionless manner with DSP and enough power. This really applies to subwoofers which this speaker really needs anyway to lower distortion in the midrange/woofer and to keep the tweeter from frying not to mention low bass. I would plug the port with expanding foam and get subwoofers. (with a 2 way crossover)
Having to satisfy the wife is not compatible with decent sound. First of all, there is no satisfying them. There is always going to be something wrong with everything. To you blossoming audiophiles out there, you have to make a deal before you get married. You get X and I get my HiFi and my own room. You can get them involved by letting them design the room around your HiFi gear.
