Yes!! it is!!! It is a Mundorf supreme, and it is by definition a FIXED!! resistor a variable resistor is a potentiometer or rheostat. I did not study the photo until now and I see they do indeed have a clamp on the resistor to change the value this is common practice with these types of resistors.
If you look at the resistor you can see the wire windings through the outer protective coating speaker designers would sand off the coating and use a clamp around the resistor to tap the wire and create the value needed. You can also see in the picture a dimple or depression in the clamp that is the exact contact point. This is also popular with other British speakers manufactures.
So, to answer the question yes this is a Mondorf supreme resistor and yes, it is 100% indeed a fixed resistor that has been modified by the installer to obtain a certain value and it is still by definition a fixed resistor. A variable resistor like a potentiometer you would just turn the knob to increase or decrease resistance. Or on a rheostat resistor you would have to slide the contact on the bar attached to the resistor to change the value making both the potentiometer and rheostat resistor variable.
Do a google image search for a rheostat resistor and you will quickly see were the idea of modifying these types of fixed resistors come from. I hope this clears up any confusion on the subject.
