Does a subwoofer amplifer exist?

I am in the process of building a sealed subwoofer and I am in the middle of searching for an appropriate subwoofer amplifier. I would prefer not to get a subwoofer plate. I have searched for a subwoofer amplifer with a built in crossover, but so far I have not been successful.

Does such a thing exist?

I thought a subwoofer plate was just a term used to describe what you are looking for, an amplifier with a crosover built in. What are you looking for that a plate amp doesn't provide? A conventional case?

Visit the Hsu Research website and check out Hsu's 500A (500 watt) subwoofer
amp. I believe that the owner's manual is available as a download. I'm using one
to power the second voice coils on my Gallo Reference 3 speakers and like it a
lot. Cost me $749 direct from Hsu. Many crossover modules are available. This
is a really serious subwoofer amp.

If you really can't find a stand alone amplifier for your sub, take a look at the ones that manufacturers send with their subs. For example, I know that Velodyne used to have a model that came with an external amplifier. You can sometimes find them for sale on ebay, more so than on audiogon. Also, you could use a regular two channel amplifier in bridge mode, and buy the Paradigm X-30 crossover to go with it?
