Marchman,
The Meadowlark Herons apparently have some way of adjusting them for a smaller room, could be a possibility. But I gotta tell ya, my Shearwaters mate beautifully with the sli80 and they go way down, definitely enough bass for me, but then again I'm not listening to very loud rock. The Shearwaters do a perfect job on acoustic bass, even Charlie Haden's super huge bottom end, no problem. If there's somewhere you can listen to them, I'd give 'em a try. Soundstaging is also top notch.
