Here is a Lowther TP-1 system that was for sale several years ago in St. Petersburg, FL. The cones and surrounds had been replaced and the systems were working like new.
Corner placement was necessary. The walls and floor were an extension of the horn loading
The driver was located in the box at the top of the enclosure and faced downwards.
View with the side and top cover removed. Low
frequencies exited through a rectangular
area in the side of the driver casting.
Here is the PM 3 driver with plaster stabilizer and
short whizzer cone. The massive magnet
structure can be seen in the bottom right picture.
