You'll find that Volt drivers are also expensive. Good bass drivers
*are* both large and expensive. They're also *necessary*, if you want
clean bass at high levels.

At no point did I say I wanted clean bass at high levels. In an earlier
thread, about bi-amping, I said that I rarely use my 20Wpc amp over half
volume for full program material. I gather an isobaric enclosure needs more
power than one using a single driver, but I don't think my needs would
dictate something in the multiple hundreds of Watts category - maybe
30-40Wpc?

Nope. If you look at the volume of air you need to shift at 20Hz to
obtain even 100dB (not a particularly loud peak level), then you need
a *lot* of power! This is why decent commercial subs invariably have
several hundred watt amps, some go up to a kilowatt!.
