From the Selmer Website:

A sophisticated bore, made from specially selected and worked ebony, has made possible the genesis of a particular tone; as a noble and living matter, the wood itself gives the “Recital” its warm, rich and round tone, with an exceptional presence (the diameter of the joints is bigger than on a traditional model, by two millimetres). A significant reserve of power and dense tonal material favour a generous playing style. A very expressive instrument for those who are looking for “a sound”. An original design for an acoustic result of rare quality.

This Selmer ‘A’ Recital Clarinet comes with 2 Backun Barrels and a Backun Bell.
