I just have one transducer, though I have considered adding a second for a little extra impact and more even coverage. I have a B&K 2 channel amp for my fronts and a B&K AV6000 Series 2 6-channel amp for my center, side & back surrounds and tactile transducer.

You could consider picking up used Marantz MA500
mono amps. They are small and unobtrusive. I see a number available on eBay right now. You could also check the classifieds here, Audiogon, Craigslist, etc.
MA500 is 125 watts/ch @ 8 Ohms. MA700 is 200 watts/ch @ 8 Ohms.
If you want something new and very affordable, this Audio Source 2 channel amp seems to be a very popular suggestion around here for people looking to add Atmos amplification. Should work well for transducers, too.

Those are just a couple of suggestions. Any quality amp will do the job.
Edit: Actually that Audio Source amp is only 50 watts/ch. You'll probably want more than that. I'd say 100 minimum with Clark Synthesis.
I've never auditioned Buttkickers so I can't vouch for them, but they have a kit that includes a wireless transmitter and 300 watt amp.

Also, you need sturdily built furniture for them to work properly. You may need to add some lumber on the bottom to tie everything together solidly. And if you are thinking about mounting them below a floor or in a platform instead of directly attached to furniture then you'll want at least two but probably four transducers and a lot of power. With multiple transducers powered by a single high power amp you'd need to do the right combination of series and parallel wiring to present the amp with a load it can handle. But we're veering way off topic for this thread. I'm sure there must be a thread on this topic here somewhere.
