Custom conversion for KEF loudspeakers Constructor_Series_Model_CS9, by Jan

Kef loudspeaker boxes (2 times) Constructor Series Model CS9 according to original KEF construction drawings. I built these boxes in 1992 from chipboard, now made from 18 mm MDF .

I bought this KEF Constructor Series Model CS9 in 1992 as a construction kit. I was faced with the choice of buying new boxes of the same quality or upgrading this KEF kit, it has become an upgrade. The 18 mm MDF used is of a hard pressing much better than the chipboard from 1992. The supplied panels, cut at an angle of 45 degrees, fit perfectly. There is one adjustment in the execution of the construction of these boxes. To upgrade the sound of this kit I replaced the capacitors of the crossover filter with better quality than those supplied in 1992 and installed an extra treble tweeter. The result in processing of the delivered panels and sound is perfect. The next project (also loudspeaker boxes) is already ready.

The outside dimensions are: height 73.2 cm width 40.2 cm depth 36.1 cm
