Orwell MK2 is a high quality two-and-a-half-way PA speaker with HiFi sound quality.
The kit provides a Celestion CDX20-3020 driver with a P-Audio PH-2380 horn as tweeter. Two Celestion FTR15-4080F are used for the bass range.
Orwell MK2 is developed by Daniel Gattig and Dennis Frank.
The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter. A 2nd order low pass filter (12 dB per octave slope) is connected to the lower woofer and has a cut-off frequency of 300 Hz. The upper woofer is connected to a 2nd. order low pass filter with a cut off frequency of 1000 Hz. In the bassrange below 300 Hz both woofers are working in parallel.
The frequency response of this speaker nearly linear. The decay spectrum shows some little horn typical artefacts. At medium volume, i.e. 95 dB at 1 m, the nonlinear distortions are lower than 1% between 150 and 5000 Hz; at a level of 105 dB at 1 m the distortion is below 1.5%.

If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).
