Advantages
The Dynaudio 21w54 is a great performing, versatile 210mm woofer that is discontinued now, but it is so good it is still in demand, can often be found used, and well worth refoaming. The driver is known for low distortion, clean 1000w impulse response, can be used in 2 or 3-way configuration, and had been used in some high end speakers like the Wilson Watt. I have been using the 21w54 in a 3-way configuration, with aperiodic damping in a single 60 liter box, and I am now considering using the 21w54 in a 2 box per channel project similar to the Watt/Puppy.
Disadvantages
The Dynaudio 21w54 is discontinued now for many years, so availability is limited, however used drivers are often up for sale. Used drivers may require refoaming if not already reconditioned, however refoam kits are readily available for the DIY-er, or can be done by your local speaker repair shop for less than the cost of a comparable new driver.
