Westminster Specification 9a differs from Specification 9 only in the fact that the Trumpet is separately available, i.e. that it can be played against the other pipes of the module. This will usually mean that it is available on two different manuals.


Our pipe modules can be installed in Westminster casework designed to accommodate them. They can also be installed in existing organ chambers if appropriately designed or in custom designed "window box" display.

Antiphonal divisions

Westminster pipe modules are well suited for usage as antiphonal divisions. Such divisions are sometimes helpful when the main organ is not well situated to propagate sound to the  far reaches of the nave. When so used, appropriate pedal resources need to be provided.
