The first version of the Grenadier XII was equipped with four US made Oxford 12K5-9 12" gold frame speakers (also known by Thomas Vox p/n 33-5084-6). A Vox sticker was added to the back of the ferrite magnet. Fender installed a similar 12" Oxford ferrite magnet speaker in their popular "Deluxe Reverb" amp. The individual speakers were rated at 20 watts RMS each. This meant that a single Gremadier XII could handle about 80 watts RMS. At that power rating, the Grenadier XII was designed for use exclusively as a vocal PA, so no miking the kick drum, please.
A later version of the Grenadier XII, model V1211, appeared in the 1969 Vox catalog. This new, shorter Grenadier XII had three Oxford 12K5-9 12" gold frame speakers plus a small Celestion high frequency horn and silver plastic grill as used in the Vox Series 90 amps. This horn was similar to the Goodmans Midax horns used in Beatle and Royal Guardsman amps.
The slender cabinet for the Grenadier XII was designed to be no larger than necessary. A chrome plated tubular "kick back" swivel stand allowed the Grenadier XII to be tilted for better sound dispersion.
A three pin male XLR jack was provided for connection of the speaker to the power amplifier. A recessed slide switch, mounted directly above the speaker jack, allowed for impedance selection of 4 or 16 ohms. A 1/4" jack, mounted near the top of the back, was used to connect the optional Vox V826 high frequency horn to the Grenadier XII. The V826 was a Goodmans Midax horn mounted to a plated pedestal (see image below).
