ScaMo 15 is a monitor with scan speak chassis. The woofer is a Scan Speak driver of the Discovery series.
Bernd Timmermanns used a simple housing for ScaMo 15 which is easy to rebuild. The crossover consists of a second-order high-pass filter and a second-order low-pass filter. A resistor in series to the tweeter adjusts the level of the tweeter to the level of the woofer. A resistor divider was not chosen because the tweeters 4 Ohms impedance should be adapted to 8 Ohms.
In Parallel to the resistor a small capacitor is used, which raises the highest frequencies, so that the speaker reaches almost 40 000 Hz in frequency response.
The frequency response of the speaker-system is very flat; the decay spectrum is excellent and the non-linear distortions remain almost consistently below 0.3% at 90 dB SPL. These are excellent characteristics.
