Celestion FTX1225 Co-axial full range

12" cast aluminium chassis full range speaker with common motor co-axial HF
Celestion's FTX series common motor co-axials offer significant advantages over conventional 2 way designs as well as over other co-axial drivers whilst retaining the improved off axis response expected in a co-axial system.

Some co-axial systems mount a separate HF unit in front of the LF cone which causes "shading' of midrange output as well as reflections back onto the cone.  Other designs place a compression driver behind the main magnet assembly and use the LF cone as a conical horn thereby eliminating the shading and reflection problems of the simple co-ax system.  Celestion have taken this one step further by utilising the main LF magnet to drive the compression driver diaphragm as well as the LF system.  This ensures accurate time alignment across the frequency range whilst maintaining excellent off axis response and compact cabinet design.

With features such as a cast chassis, edgewound voice coils, sound castle diaphragm clamping and a demodulation ring the FTX1225 offers the best of Celestion design and manufacture.
