John,
Having heard your system in your room, and reflecting on time spent working with similar woofers in similar cabinets, my guess is the box/port is tuned too high for your room.
The two easiest ways to tune the systme lower are to either decrease the port diameter, or increase the port length, or some combination of both.
The easiest way to tune the system lower is the straw trick that someone mentioned. First though, cut the straws to the length of the port (you should be able to easily measure by hooking a tape measure on the inside lip). First put them all of the way in, by default the area that the straws take up will slightly lower the tuning frequency, but you can slide them in and out to alter the tuning frequency. 1/8 of an inch at a time will probably be adequite. But based on what I heard in your room, the port should be 1/2 to 3/4" longer than it is, possibly more depending on your tastes. This should hopefully give you a sound somewhere between sealed and vented, and slightly deeper bass. When lengthening the port, I recomend moving the straws outward, away from the inside of the cabinet. This way, you will not end up getting too close to anything inside of the cabinet like a wall or crossover components. This will prevent any turbulence noises from happening during lower bass notes.
This should really help things quite a bit as the tuning of the Lorelis in your room really seemed to react with some room resonance. Most ported speakers need to be 'tuned' to fit the room anyhow.
I still have your CD, I forgot to bring it when I came over the second time.
Have a good one John,
