Best subwoofer match for Meadowlark Swifts?


Trying to expand to a 5.1 system from my current setup. I'm using a NAD T752 with the Meadowlark Swifts, but planning to upgrade to separates eventually. I thought Meadowlark made a sub, but can't find it anywhere. Thanks for the help.

Love to have the Tegmentum, but it is out of my range. When I have that kind of cash I'll put it into separates first. Any suggestions that are more in the range of REL Q100e used... max $600?

Thanks for the responses, and sorry for not putting the price range in the initial query.

I am strongly considering the Swifts to be the first stage of a total HT upgrade. One sub I was thinking about was the Hsu 1220... seems to have gotten raves for years for both HT and music. The REL would be a great choice... I may have to add that one to my list.

btw, could you share a few thoughts about the Swifts?
rb- The swifts are awesome! I don't have the ear or experience that some on this site do, but even I can tell that they present an excellent soundstage. Overall I would say they were neutral to a little bright- but that just being shocked by good clean sound after years with a pair of Klipschs. The bass could be a little more expansive (especially for HT purposes without a sub,) but again that's me coming off the bloated Klipschs. I listened to some B&W 602's and 603's, as well as Vandersteen 1C's when I was shopping around and ended up buying the Swifts without hearing them. (the reviews were that good!) I didn't make a mistake. The Vandy's outdid the B&W's fairly easily, but they are huge and somewhat delicate without a cabinet (an oversized scratching post for the cats.) The Swifts soundstage isn't quite what the Vandersteen's was, but I think they are actually cleaner sounding than the Vandys (which seemed a little muted) and had more bass.

Thanks for the suggestion,
