Again, despite the low impedance at 80Hz or so, the speaker is easy to drive. We got walloping bass using our MA-1 amplifier which is an OTL, which are not known for driving low impedance loads.
So if you have 100 watts of good quality, tube or solid state, you'll be able to make this work, unless you have a large room. It is sensitive to speaker cables though, so you may have to audition them to find a combination that works.
