A cello endpin consists of the turned barrel and the rod, which passes through the barrel into the body and stands on the floor below. Inside, the barrel is lined with cork so that the rod slides smoothly. The rod material shapes the sound measurably: in a series of measurements at AGH Kraków (2023) a rod of reinforcing steel gave the darkest sound in the low-frequency range, a hollow aluminium tube the brightest, with beech in between. Between the two extreme materials the spectral centroid differed by 102.6 hertz on the A string and by 30.1 hertz on the C string. Our titanium lies between steel and aluminium in density, closer to aluminium.
Our 3S-509 and 3S-515/516 cello endpins come with an ebony or rosewood barrel and a steel, carbon or titanium rod. The carbon models 509E-C and 515E-C are identical in construction and differ only in their fittings, nickel-plated on the 509 and gold-plated on the 515. With a replacement rod the diameter must suit the barrel: our cello barrels for steel take 8 millimetres, our carbon rods are 10 millimetres.
Our experience: the lighter the rod material, titanium for instance, the brighter the instrument sounds; the standard is a wooden barrel with a steel rod. The Kraków study did not measure titanium or carbon; this part rests on our workshop practice. A carbon rod makes the endpin lighter and wears with time.
If you want barrel and rod together, you will find them in our 3S-509 and 3S-515/516 cello endpins; if you only want to change the sound through the rod, in our replacement rods in steel, carbon and titanium.
Yes. In the study by Gorazd and Pochel (2023), of three materials tested a reinforcing-steel rod sounded darkest in the low-frequency range and a hollow aluminium tube brightest.
The rod must suit the barrel. Our cello barrels for steel rods take 8 millimetres, our carbon rods are 10 millimetres.
On the carbon model only in the fittings: nickel-plated on the 509E-C, gold-plated on the 515E-C.
