Warm speakers?

Hello, in my current system I'm listening to a pair of Meadowlark Audio Kestrel Hot Rods in a very small room. We are preparing to move into a new house where I'll get a larger listening room (13X14). I would like to get larger speakers but maintain the Kestrel's sonic characteristics. If asked to decribe the Kestrels in one word I'd say "warm" without hesitation. Anyone have a suggestion for similar sounding speakers that go lower than Kestrel's 38HZ in the $1K to $1.5K range used? I have a feeling when the Kestrels will be too small for the new room.
Rest of system is NAD C-541i and Portal Panache. Thanks.
