Well regarded driver, Seaton even used them in some of his subs. It's been a while but a memory says that size box is not optimal for a sealed box (but would work well).
I'm not a fan of plate amps, I use pro amps (Crown XLS in my case, supported by miniDSP 2x4 for dsp). Fan noise can be a consideration (the XLS are very quiet, tho), but something like the Behringer iNuke DSP series amp has it all in one box for a great price and used by quite a few DIYers, but has noisy fans and fan mods have been somewhat an issue for some.
Note that for a sealed box the dsp is more about eq capabilities, but even Audyssey can do a decent job; if its a ported box you may also need a high pass filter to protect the driver. That bundle without amp is $385 if you didn't see that.
