One pair of Millbank Speakers.
for wall mounting, dimensions approx three feet tall by nine inches wide and seven deep.
each box contains four seven inch mid-range speakers ( i always meant to change two in each for a woofer and tweeter, but never got round to it) damn good stereo sound anyway. the boxes are a mahogany colour with blackcloth mesh detachable fronts.
cost £25 in 1978. my browser wont post pictures buyer has to collect as post would be prohibitive to size/cost
